OPERATIN INSTRUCTIONS

The DVM-80UVM requires one 9V lithium or alkaline battery, which powers

the unit and activates the backlight. The meter will shut off automatically a

few minutes after the display reads zero, but not while voltage measurements

are being made. The DVM-80UVM includes an elbow test point reading feature,

which is displayed by a blinking decimal point ( . ) and a Peak Hold feature which

is indicated by all decimal points flashing.

To activate the Peak Hold feature, press the Peak Hold button. The display will hold

the highest reading while Peak Hold is activated. To deactivate the Peak Hold and

clear the display, press the Peak Hold button again.

NOTE: The meter will not shut off while a peak reading is displayed.

The backlight is always on when the unit is powered on. The low battery feature will

simply shut off or will not turn on the meter when the battery is low. The unit has a 0.4”

LCD display that indicates 3-1/2 digits. The DVM-80UVM measures RMS AC and DC.

To take readings above 40kV, attach one R-80 resistor stick on each meter stick,

and then multiply the reading on the display by two (for example, if the display

reads 30kV with add-on resistor sticks installed, multiply 30 times 2 = 60.0kV).

Do not exceed 80kV with the R-80 resistor sticks attached.

PRE-USE INSPECTION

WARNING: Before using the instrument be sure to test and inspect the equipment

to ensure that it is functioning properly and is in safe, working condition. Failure to do

so may cause serious injury or death and may result in erroneous test measurements.

Before making any high voltage measurements, test and inspect the

voltmeter/phaser as follows:

1) Make certain the instrument is clean, dry and waxed to a clear shiny surface.

2) Inspect the cord for cracked insulation.

3) Be sure that you are using hot sticks of the appropriate length, and examine each

hot stick to ensure that it is clean, dry and waxed to a clear shiny surface.

4) Attach the appropriate probes for overhead or underground applications (see page 9)

and ensure that the probes are properly installed and tightened (do not overtighten).

5) Install add-on resistor sticks if necessary for the range being tested.

6) Test the voltmeter/phaser with a proof tester such as the HD Electric PT-5000B

Proof Tester Voltmeter Tester (see page 10).

Voltage and Phasing Measurements – Line-to-Line

We recommend that two person crews perform all line-to-line voltage measurements

and phasing operations. Since the operation is occurring near two energized conductors,

OPERATIN INSTRUCTIONS continued

the use of two person crews allows each person to operate one meter stick and maintain

high safety standards.

In order to make line-to-line measurements, each probe must contact an energized line.

Be sure that only those probes intended for the particular application are used (see page

9). Always keep the connecting cord free and clear of energized phases and ground.

For phasing applications, the probes will be placed on opposite sides of an open point,

typically a switch. The phasing operation will indicate if two sides of a line are in-phase

before closing a switch.

To check all phases, proceed as follows:

1) Measure voltage on each phase from line-to-ground to verify all phases are

live and at the same voltage.

2) Place one of the probes on a conductor on one side of the switch.

3) Place the other probe on one of the three phases on the other side of the switch.

4) If the conductors are out-of-phase, the meter will read line-to-line voltage.

If they are in-phase, the meter will read near zero but may read up to 15% of

the line-to-line voltage.

5) Continue this procedure with all three phases on both sides of the switch.

If an intermediate reading is found, the phasing cannot be determined by this

method and the switch should not be closed until other means are used for phasing.

Voltage Measurements – Line-to-Ground

Keep the connecting cord free and clear while testing.

To use this two-stick voltmeter/phaser, first connect one of the probes to either

a ground or system neutral making sure the resistor stick is making contact at all

times during measurement. The other probe should be connected to the energized

source to be measured.

Maintain contact only long enough to read the meter. Always remove the probe

from the energized source first before removing the ground connection.

TEST POINT EASURE ENTS

The DVM-80UVM includes a Test Point feature for measuring voltage from elbow test

points. To activate Test Point mode simply push the ON button again. Test Point mode

is indicated by a blinking decimal point. To turn Test Point mode off, simply push the ON

button once again and the decimal point will stop blinking. When using a voltmeter/phasing

set to phase between test points, the important measurement is whether high voltage is

present or not. The proper procedure for phasing between elbow test points is as follows:

1) Both elbows must be energized. Follow the proper safety practices for removing

the test point protective caps and exposing the live test points. Treat all exposed

electrodes as energized high voltage. Measure from both elbow test points to

ground. These measurements should show that both elbows are energized and,

if both elbows are of the same type and manufacture, should measure the

approximate line voltage.

OPERATIN INSTRUCTIONS continued

2) Measure from one elbow test point to the other. This reading will show either a

high voltage reading indicating the elbows are out-of-phase or a zero or low voltage

reading indicating the elbows are connected to the same phase. The out-of-

phase measurement will likely not show the higher voltage expected from

a phase-to-phase measurement but will be closer to the line-to-ground

voltage. The in-phase voltage measurement can be between zero and 15%

of the nominal line-to-ground voltage. If both elbows are of different type and

manufacture, then a higher reading may occur.

PEAK HOLD

The DVM-80UVM includes a Peak Hold feature. To activate the Peak Hold feature

press the Peak Hold button. Peak Hold is indicated by all decimal points flashing.

The display will hold the highest reading while Peak Hold is activated. To deactivate

the Peak Hold and clear the display, press the Peak Hold button again.

Note: The meter will not shut off while a peak reading is displayed.

CARE AND AINTENANCE

Periodic regular maintenance is required to keep the voltmeter in proper operating condition.

Keep the voltmeter clean and dry and always store it in its case. The fiberglass sticks

should be kept clean and free of dirt, contamination and marking. Examine the cord for

cracking or other damage prior to each use. Although we don’t specify a calibration cycle,

we recommend you test, measure and calibrate your instrument annually. The Calibration

and Maintenance Log provided on page 15 can be used to record these events.

Contact HD Electric Company for details.

CLEANING INSTRUCTIONS: To clean the DVM-80UVM wipe with a damp cloth with water.

Do not use harsh chemicals or solvents.

PROBES AND ACCESSORIES

WARNING: ALWAYS use probes appropriate to your application. NEVER use overhead

probes in underground applications. Failure to use the correct probe can result in arcing

or electrical contact and may cause serious injury or death. If you are not trained in the

particular operation or are not sure about the appropriate probe for your application

DO NOT PROCEED.

The DVM-80UVM comes standard with two overhead hook probes (025-OLPS-5), a

PROOF TESTER®

VOLT ETER TESTER

The PT-5000B Proof Tester

Voltmeter Tester will produce

5kVDC at the test leads to

confirm proper operation of

voltmeters and phasers. This

tester should be used only with

voltmeters/phasers that measure

DC voltage. It will not confirm

operation of voltmeters/

phasers that measure AC

voltage only. The PT-5000B

operates from one 9V lithium

or alkaline battery and

produces approximately

5kVDC at the connecting

leads. To use:

1) Connect both tester leads

to the voltmeter/

phaser probes.

2) Press and hold both

TEST buttons.

3) Confirm a good battery

by checking the red light

on the Tester. If the red light

does not come on, replace

the battery with a 9V lithium or alkaline only.

4) Verify the voltmeter/phaser reads approximately 5kV.

5) Release the TEST buttons and disconnect the Tester from the voltmeter/phaser.

WARNING: Do not use the voltmeter/phaser if proper operation is not confirmed.

WARNING: Do not use this tester except as directed. Do not use to test equipment

other than voltmeters/phasers. Do not apply to energized circuits or equipment. Refer

all servicing to the factory. Failure to follow these instructions may lead to electric

shock, severe injury or death.

CABLE FAULT TESTER

The CFT-35 Cable Fault Tester is for

use only with two stick voltmeters

for testing leakage

current in underground

primary voltage cables.

The CFT-35 can be used

on underground cables with grounded neutrals with a maximum line-to-ground voltage of

21.1kV or maximum line-to-line voltage of 36.6kV. Operation at higher voltages may

damage the CFT-35 and provide erroneous test results.

The CFT-35 is used with a voltmeter/phaser for testing installed or repaired underground

cable prior to energizing it. Only cable with extruded dielectric such as rubber or polyethylene

can be tested with the CFT-35. Using the CFT-35 on paper insulated cable may provide

erroneous test results caused by higher leakage currents typical for this type of cable.

The CFT-35 contains a high voltage rectifier and is connected to test underground

primary cable as shown in this circuit:

In practice, the CFT-35 rectifies the high voltage from the source, usually a transformer

primary, and charges up the cable, shown as a capacitor above. When a connection is

first made, the DC from the CFT-35 will charge up the cable capacitance through the

resistors in the meter sticks. If the cable is good, current will stop flowing when the

cable is charged up. If the cable is not good, the cable will not charge and current will

continue to flow, as indicated by a higher meter indication.

The following equipment is required for testing cable with a CFT-35:

1) An HD Electric two-stick voltmeter/phaser.

2) The CFT-35 Cable Fault Tester.

3) For deadfront applications, ASP bushing probe(s) or, for live front

applications, CP-1 probe(s). An EA-15/25 elbow probe may also

be used for deadfront applications.

4) For deadfront applications, a feed-through bushing may also be used.

PROBES AND ACCESSORIES continued

CFT-35

PROBES AND ACCESSORIES continued

Shown here is a typical application

of the CFT-35 and associated equipment

for testing underground cable from

a pad-mount dead front transformer:

Before using the

CFT-35, read and

understand all of

the instructions and

precautions for live

testing with voltmeters/phasers

(pages 7 & 8). In addition, be

sure to consult your company’s work

practices and any information provided

by the manufacturers of the apparatus

that you are testing.

Testing using the CFT-35 should

be performed as follows:

1)Test the cable with the HDE voltmeter/phaser to ensure

that it is not energized and that it is discharged.

2)Ensure that the cable to be tested is completely

isolated; that both ends have no other connection

to voltage or to a transformer winding

and are properly terminated.

3)Assemble the CFT-35

with appropriate

probe on the

voltmeter/phaser

stick with the meter.

4)Assemble the appropriate probe on the voltmeter/phaser stick without the meter.

5)Connect the voltmeter/phaser stick without the meter to the cable to be tested.

5)Connect the voltmeter/phaser stick with the CFT-35 to the voltage source.

6)Read the display on the voltmeter/phaser. The reading will be initially high.

For a short cable, the reading should return quickly to near zero.

For a longer cable, it may take a few seconds for the reading to return to near zero.

8)If the reading does not return to near zero after several seconds, the cable is

leaking or shorted and the test should be discontinued. Remember that all HDE

voltmeters/phasers are intermittent duty devices and should be connected only as

long as necessary to obtain a reading.

9)Discharge the cable by removing the voltmeter/phaser from the line, removing

the CFT-35 from the voltmeter/phaser and connecting the voltmeter/phaser from

cable to ground.

Cable Fault Tester

and Bushing Probe

PROBES AND ACCESSORIES continued

With the DVM-80UVM, if the cable is completely shorted the meter will read the line

voltage times 0.71. For a nominal 7.2kV circuit the meter will read approximately 5.1kV.

Listed here are the actual cable leakage currents for voltage readings on the

DVM-80UVM digital meter: Meter reading of 0.5kV = 8uA

Meter reading of 1.0kV = 16uA

Meter reading of 2.0kV = 31uA

for at the time of delivery. While HDE will use all reasonable commercial efforts to maintain the delivery date(s) acknowledged or quoted by HDE, all shipping dates are approximate and not guaranteed. HDE reserves the

right to make partial shipments. HDE, at its option, shall not be bound to tender delivery of any oods for which Buyer has not provided shipping instructions. If the shipment of the oods is postponed or delayed by Buyer for

any reason, Buyer agrees to reimburse HDE for any and all handling and storage costs and other additional expenses resulting therefrom. All claims for shipping errors, lost shipments or any other discrepancies must be

made within ninety (90) days or they will be disallowed and deemed waived.

4. HDE LI ITED WARRANTY: HDE covers its products with a manufacturer’s warranty against defects in material or workmanship for a period of ten years in the case of Capacitor Controls and in all other circumstances

for a period of one year, unless otherwise stated by HDE in writing. To take advantage of this warranty, the complete product must be delivered prepaid to HDE or any HDE Authorized Service Center. This warranty shall not

apply to any oods including but not limited to products which: (a) Have been repaired or altered outside HDE’s factory (or Authorized Service Center) or in any manner so as, in HDE’s judgment, to affect its serviceability or

proper operation; (b) Have been subjected by persons other than HDE (or Authorized Service Center) to improper handling, operation, maintenance, repair or alteration; and, (c) Have been subjected to normal wear and tear,

misuse, negligence, improper installation or accident. HDE’s obligation under this warranty, and the Buyer’s exclusive remedy for the breach thereof, shall be limited to, at HDE’s option, repair or replacement of any allegedly

defective oods or issuance of credit. HDE requires the return of any allegedly defective oods, transportation prepaid, before honoring any claim. All returned oods are subject to inspection, and if examination does not

disclose any defect covered by this warranty, replacement of such oods or issuance of credit for same will not be approved.

THE FORE OIN CONSTITUTES HDE’S SOLE WARRANTY RESPONSIBILITY AND BUYER’S EXCLUSIVE REMEDY WHETHER SOUNDIN IN TORT, CONTRACT, STRICT LIABILITY OR OTHERWISE, EXCEPT

AS OTHERWISE EXPRESSLY SET FORTH IN THIS A REEMENT. THERE ARE NO OTHER WARRANTIES, EXPRESS OR IMPLIED, WHETHER OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE,

OR OTHERWISE. No employee, agent, dealer, or other person is authorized to give any warranty on behalf of HDE. This warranty extends only to persons or organizations who purchase the oods from HDE for resale.

5. LI ITATION OF RE EDY AND LIABILITY: THE SOLE AND EXCLUSIVE RE EDY FOR BREACH OF ANY WARRANTY HEREUNDER SHALL BE LI ITED TO REPAIR, CORRECTION, REPLACE ENT OR CREDIT

UNDER SECTION 4. HDE SHALL NOT BE LIABLE FOR DA AGES CAUSED BY DELAY IN PERFOR ANCE, AND IN NO EVENT, REGARDLESS OF THE FOR OF THE CLAI OR CAUSE OF ACTION (WHETHER

BASED IN CONTRACT, INFRINGE ENT, NEGLIGENCE, STRICT LIABILITY, OTHER TORT OR OTHERWISE), SHALL HDE’S LIABILITY TO BUYER AND/OR ITS CUSTO ERS EXCEED THE PRICE PAID BY BUYER

FOR THE SPECIFIC GOODS GIVING RISE TO THE CLAI OR CAUSE OF ACTION, AND BUYER SHALL INDE NIFY HDE FOR ANY DA AGES IN EXCESS THEREOF. BUYER AGREES THAT IN NO EVENT

SHALL HDE’S LIABILITY TO BUYER AND/OR ITS CUSTO ERS INCLUDE SPECIAL, INDIRECT, INCIDENTAL, CONSEQUENTIAL OR PUNITIVE DA AGES OF ANY CHARACTER IN CONNECTION WITH THE

SALE, RESALE OR USE OF THE GOODS, WHICH ARE WAIVED BY BUYER AND AS TO WHICH BUYER SHALL INDE NIFY HDE. The term “consequential damages” shall include, but not be limited to, loss of an-

ticipated profits, business interruption, loss of use of revenue, cost of capital or loss of or damage to property, equipment, or data, or loss of reputation. Further, Buyer shall indemnify and hold HDE harmless from any liability

to Buyer, Buyer’s employees, workers, contractors or any other persons arising out of Buyer’s, and any other persons’, use of the oods. All instructions and warnings supplied by HDE will be passed on to those persons who

use the oods. HDE’s oods are to be used in their recommended applications and all warning labels adhered to the oods by HDE shall be left intact. It is impossible to eliminate all risks associated with the use of the

oods. Risks of serious injury or death, including risks associated with electrocution, arcing and thermal burns, are inherent in work in and around energized electrical systems. Such risks arise from the wide variety of elec-

trical systems and equipment to which oods may be applied, the manner of use or application, weather and environmental conditions or other unknown factors, all of which are beyond the control of HDE. HDE does not

agree to be an insurer of these risks, and shall have no liability for any claims arising from such risks. WHEN YOU BUY OR USE THESE PRODUCTS, YOU A REE TO ACCEPT THESE RISKS.

HDE’s reasonable control. Deliveries or other performance may be suspended for an appropriate period or cancelled by HDE upon notice to Buyer in the event of any of the foregoing, but the balance of this agreement shall

otherwise remain unaffected. If HDE determines that its ability to supply the total demand for the oods, or to obtain material used directly or indirectly in the manufacture of the oods, is hindered, limited or made impracti-

cable due to causes set forth herein, HDE may allocate its available supply of the oods or such material (without obligation to acquire other supplies of any such oods or materials) among itself and its purchasers on such

basis as HDE determines to be equitable without liability for any failure of performance which may result therefrom.

7. CHANGES: HDE reserves the right to change designs and specifications for standard oods without prior notice to Buyer, but not with respect to custom oods being made for Buyer. HDE shall have no obligation to in-

stall or make such change in any oods manufactured prior to the date of such change.

10. INSPECTION/TESTING: Buyer, at its expense, agrees that it will promptly inspect the oods upon receipt thereof, and in no event later than thirty (30) days from the date of receipt of the oods. Buyer shall deliver to

HDE within fifteen (15) days of inspection, but in no event later than forty-five (45) days from the date of receipt of the oods, written notice of any and all deficiencies, defects, variations from specifications or complaints of

any kind with respect to the quantity, quality, condition, shipment, performance, price or appearance of the oods so received by Buyer. In the event no such written notice is received by HDE, Buyer shall be deemed con-

clusively to have inspected and accepted all such oods unconditionally and to have waived any and all rights and claims, including without limitation any right to reject the oods or to claim damages in respect thereof. Buyer

may not return goods without first advising HDE of the reasons therefore, obtaining from HDE a material authorization number and observing such instructions as HDE may give in authorizing such return. In the event a re-

turn is authorized by HDE, a restocking for any oods requiring repackaging or maintenance a twenty percent (20%) restocking fee shall be assessed to Buyer in the final credit amount.

11. SERVICES: If this agreement requires HDE to perform or provide any services, HDE (including without limitation its successors, assigns, agents or any person or entity acting at HDE’s direction) shall not be responsible

for any damages, claims, liabilities or expenses of any nature arising out of such services.

12. U.S. EXPORT CONTROL LAWS: All oods sold to Buyer by HDE hereunder are subject to U.S. Export Control Laws. Buyer hereby agrees not to re-sell or divert any goods contrary to such laws.

13. CO PLIANCE: Seller/Contractor shall comply with all applicable federal, state or local laws, rules, regulations, or orders. Seller/Contractor shall comply with Executive Order 11246, as amended by Executive Order 11375,

abandonment, or waiver of these terms and conditions shall be binding upon HDE unless made in writing and signed on its behalf by its duly authorized representative. No conditions, usage or trade, course of dealing or per-

formance, understanding or agreement purporting to modify, vary, explain, or supplement these terms and conditions shall be binding unless hereafter made in writing and signed by Seller. No modification shall be effected

by HDE’s receipt or acceptance of Buyer’s purchase orders, shipping instruction forms, of other documentation containing terms at variance with or in addition to those set forth herein, all of which are objected to by HDE. Any

such modifications or additional terms are specifically rejected by HDE. No waiver by HDE with respect to any breach or default of any right or remedy and no course of dealing, shall be deemed to constitute a continuing

waiver of any other breach or default of any other right or remedy, unless such waiver be expressed in writing and signed by HDE. All typographical or clerical errors made by HDE in any quotation, acknowledgment or pub-

lication are subject to correction. Validity and performance relating to the interpretation and effect of this agreement shall be governed by the laws of the state of Illinois without regard to its conflict of law principles.
