1.2 Precautions
This product has been designed with your safety in mind, but please
pay attention to the following warnings and cautions before use.
Warnings
In order to avoid the danger of electrical shock, it is important that
proper safety measures are taken when working with voltages
exceeding 30V AC rms, 42V AC peak or 60V DC.
Before use check the unit for cracks or any other damage. Make
sure the unit is free from dust, grease and moisture. Also check any
associated accessories for damage. Do not use if damaged.
Do not use if the battery cover is not fitted.
Cautions
Avoid severe mechanical shock or vibration and extreme
temperature.
To avoid corrosion from leaking batteries, remove the batteries
when the unit is not in use for an extended period.
Do not short the output terminals.

2. INTRODUCTION
2.1 Inspection
Examine the shipping carton for any sign of damage. Inspect the unit
and any accessories for damage. If there is any damage then consult
your distributor immediately.
2.2 Description
PD440SX
The PD440SX is a portable battery powered proving unit for the
testing of contact type voltage detectors up to 440V.
PD690SX
The PD690SX is a portable battery powered proving unit for the
testing of contact type voltage detectors up to 690V.
Both the PD440SX and the PD690SX ramp output voltage down in a
sequence lasting for a duration of 10s, before reducing output voltage
to zero.

3. OPERATION
Caution
Always make sure the precautions and limitations of the unit being
tested are observed. If necessary refer to the specification of the unit
being tested.
Also refer to the graph of typical output voltage under various load
conditions at the rear of these instructions.
3.1 Proving Unit LED indications
LED Proving unit model No. LED illumination indicates
High Voltage All models High voltage output at proving
unit terminals
Low Battery All models Proving unit batteries are low
Replace batteries
3.2 Proving a Test Lamp, Voltage Tester/Indicator, DMM etc.
Place one probe of the unit under test into the left hand socket of the
proving unit until it makes contact with the terminal. Place the other probe
into the right hand terminal of the proving unit and gently press down.
Observe that the required indicators on the unit under test illuminate,
then withdraw the probe from the right hand terminal first, and then
the left.
The voltage LEDs will illuminate according to the output voltage. This
will start at the maximum voltage for about 4s and then ramp down to
50V over about 4s. The voltage will be held at 50V for about 2s after
which the output voltage will fall to zero and a low resistance will
appear across the terminals verifying the continuity function on two
pole testers.
PD440SX PD690SX instruct V1.indd 11 02/09/2019 13:11:59

During the sequence, the LEDs will indicate the actual output
voltage level as affected by load, not the no load output. Refer to the
graph of typical output voltage under various load conditions at the
rear of these instructions.
If none of the proving unit LED’s illuminate when performing the
above tests check the condition of the proving unit batteries and
replace them if required (see section 4.1).
3.3 Test Lamp, Voltage Tester/Indicator Cables
During the above tests, emphasis should also be placed upon the
flexing of the UUT cable along its length, and particularly at the
entry points to the hand held elements, to confirm that the cable has
not fractured.
It may be necessary to perform this test a number of times as the
proving unit times cut out after 10s.
3.4 CALCHECK
The CALCHECK feature may be used to check that a multifunction
tester, insulation tester or continuity tester is maintaining ongoing
accuracy between calibrations. There are two insulation test
resistance values, 0.5M Ω and 1M Ω. There are also two continuity test
resistance values,
0.5 Ω and 1 Ω.
One probe of the tester being checked should be placed on the
desired resistance value and the other probe should be placed on
the COM terminal, following the instruction manual for the tester
being used.
The CALCHECK feature is not designed to be used to check loop
testers, where the high test current will damage the proving device.
PD440SX PD690SX instruct V1.indd 14 02/09/2019 13:11:59

The CALCHECK feature can be used as a regular check that
instruments are not drifting between calibrations. Records can be
kept using the CALCHECK Verification Measurement sheet at the
back of this manual. An initial measurement can be taken soon after
calibration and the results recorded. Further checks can be made
periodically, e.g. every month, and the results also recorded on the
sheet. Further copies of the sheet can be downloaded from the
Martindale Electric Co Ltd website.

4. MAINTENANCE
4.1 Battery Replacement
Remove the rear battery cover by turning the quarter turn screw 90°
anti-clockwise and then lifting the cover. Observing correct polarity
fit 6 new 1.5V, AA alkaline batteries (IEC LR6, NEDA 15A). Replace
the battery cover by positioning the top onto the rear casing slots,
lowering the cover and then locking by turning the quarter turn
screw 90° clockwise.
Note: Do not mix old and new batteries.
4.2 Cleaning
If contamination is found, clean with a damp soft cloth and if
necessary a mild detergent or alcohol. Do not use abrasives,
abrasive solvents, or detergents which can cause damage to the
unit. If a mild detergent is used, the unit should subsequently
be thoroughly cleaned with a water dampened soft cloth. After
cleaning, dry and allow to remain in a dry environment for 2 hours
before use.
4.3 Repair and Service
There are no user serviceable parts in this unit other than those that
may be described in section 4. Return to Martindale Electric if faulty.
Our service department will quote promptly to repair any fault that
occurs outside the guarantee period.
Before the unit is returned, please ensure that you have checked
the unit and batteries.
4.4 Storage Conditions
The instrument should be kept in cool, dry conditions and not
subjected to shock, scratching or other damage, prolonged direct

harsh sunlight, extremes of temperature and in such a manner as
to preserve the working life of the unit. It is strongly advised that the
unit is not kept in a tool box where other tools may damage it.
