1 Applications
The METRISO 3000 measuring and test instrument allows quick
and efficient testing and documentation of ESD protective mea-
sures in the EPA (electrostatic protected area).
The test instrument is suitable for:
• The selection of ESD materials
• Installation of selected protective measures
• Periodic inspection of protective measures
With the help of the METRISO 3000, you can perform all relevant ESD
measurements in accordance with IEC 61340-4-1, IEC 61340-2-3 and
IEC 61340-4-5.
Thanks to the USB data interface integrated into the
METRISO 3000, stored measured values can be transmitted to a
PC, where they can then be printed and archived. This is of spe-
cial significance where product liability is concerned.
The following measurements and tests can be performed with the
METRISO 3000:
• Resistance to ground, point-to-point and surface resistance,
as well as volume resistance (with special measuring probes)
• Temperature and atmospheric humidity (with special sensor
included in METRISO 3000 Measuring Kit no. 7100.3000.MK)

2 Safety Features and Precautions
The electronic measuring and test instrument is manufactured
and tested in accordance with safety regulations IEC/EN 61010-
1/VDE 0411-1 and EN 61557. When used for its intended pur-
pose, safety of the operator, as well as that of the instrument, is
assured.
Read the operating instructions thoroughly and carefully before
using your instrument. Follow all instructions contained therein.
The measuring and test instrument may not be placed into
service:
• If the battery compartment lid has been removed
• If external damage is apparent
• If connector cable or measuring adapters are damaged
•Iftheinstrumentnolonger functions flawlessly
• After extraordinary stressing due to transport
• After a long period of storage under unfavorable conditions
(e.g. humidity, dust or extreme temperature)
Data Backup
We advise you to regularly transfer your stored data to a PC in
order to prevent potential loss of data in the test instrument.
We assume no responsibility for any data loss.
We recommend ETC software (Electric Testing Center) for back-
ing up, processing and managing data.

charger)
Attention!
Only rechargeable batteries may be inserted when the char-
ger is connected.
EC mark of conformity
The device and included batteries may not be dis-
posed of with the trash.
3 Initial Start-Up
3.1 Battery Test
Four different battery symbols, ranging from fully depleted to fully
charged, continuously indicate the momentary charge level in the
upper left-hand corner of the display
If battery voltage has fallen below the allowable lower
limit, the pictograph shown at the right appears. The
instrument does not function if the batteries have been depleted
excessively, and no display appears.
3.2 Installing or Replacing Batteries
New batteries must be inserted for initial start-up, or if only 1 filled
segment remains in the battery symbol.
Attention!
!
Before opening the battery compartment (see page 5 for
location), disconnect the instrument from the measuring
circuit (mains) at all poles.
Eight 1.5 V size AA batteries in accordance with IEC LR 6 are
required for operation of the high-impedance measuring instru-
ment. Use new alkaline manganese batteries only.
Rechargeable NiCd or NiMH batteries may also be used. These
can be charged externally or by connecting the Z502R charger to
the test instrument. We recommend rechargeable NiMH batteries.
Always replace batteries in complete sets.
Dispose of batteries in an environmentally sound fashion.
➭Loosen both slotted screws for the battery compartment lid
on the back, and remove the lid.
➭Remove the battery holder and insert eight 1.5 V size AA bat-
teries with correct polarity in accordance with the symbols.
Attention!
!
Make sure that all of the batteries are inserted with correct
polarity. If just one battery is inserted with reversed polar-
ity, it will not be recognized by the instrument and may
result in leakage from the batteries.
➭Push the battery holder into the battery compartment such
that the battery holder’s contacts touch the contact springs at
the bottom of the battery compartment (see drawing on
page 3).
If the battery holder is not inserted as specified, the instrument
cannot be supplied with power.
➭Replace the battery compartment lid and retighten the
screws.
Attention!
!
The instrument may only be placed into service if the
battery compartment lid is securely fastened!
3.3 Charging the Batteries in the Tester
Attention!
!
Use only the Z502R charger (available as an accessory)
to charge batteries which have already been inserted into
the test instrument.
Make sure that the following conditions have been fulfilled be-
fore connecting the charger to the charging socket:
– Rechargeable batteries have been installed with
correct polarity (not standard batteries)
– The test instrument has been disconnected from the
measuring circuit at all poles
– The instrument must remain off during charging.
Refer to section 12.2.1 with regard to charging batteries which
have been inserted into the tester.
If the batteries or the battery pack have not been used or
recharged for a lengthy period of time (> 1 month), thus resulting
in excessive depletion:
Observe the charging sequence (indicated by the LED at the
charger) and initiate a second charging sequence if necessary
(disconnect the charger from the mains and from the test instru-
ment to this end, and then reconnect it).

4 General Operation
4.1 Connecting the Instrument
The test leads are connected to the “+” and “COM” jacks.
When resistance in the G
range is measured, the shielded
cable (included) should be con-
nected to the COM and SHIELD
jacks. Be sure to observe color
coding.
4.2 Switching On,
Monitoring and Switching Off
If supply voltage drops to a value of less than 8.5 V, the
LOW BATT pop-up message appears: No more measurements
can be started.
If battery voltage falls below the allowable limit value of 8.0 V the
instrument cannot be switched on, or it is switched off.
Nor can measurements be started in the resistance measuring
ranges in the event of interference voltage.
The instrument only switches itself off automatically after comple-
tion of an (automatic) measuring sequence, and after the prede-
termined on-time has expired (see page 8). On-time is reset to its
original value as defined in the setup menu, as soon as any key or
the rotary function switch is activated.
If the instrument is switched off automatically with the rotary
switch in any position other than OFF, it can be reactivated by
pressing the ESC key. The instrument is also reactivated if the
rotary switch is activated and turned through the OFF position.
The instrument can be switched off manually by turning the rotary
switch to the OFF position.
4.3 Optical Indicators
1Function testing should be executed at regular intervals (see following
section regarding testing the LEDs).
Testing the LED which Indicates Detection of Interference Voltage
when Switched Off – OFF Switch Position
➭Apply a voltage of greater than 50 V (+ and COM jacks).
➭Turn the rotary switch to the V position.
➭Read the voltage value at the LCD.
➭Turn the rotary switch to the OFF position.
Test results: If applied voltage is unchanged and the LED which
indicates the detection of interference voltage lights up red, the
LED is OK. In this case, the LED reliably indicates interference
voltage even when the instrument is switched off. We recom-
mend executing this test at regular intervals.
METRISO 3000 Measuring Functions, Measuring Ranges and Limit

Note
Checking Measurement Cables Before Measurements
Before performing resistance measurement, the test
probes on the measurement cables should be short-cir-
cuited in order to assure that the instrument displays a
value of less than 1 k(see section entitled “Measuring
Resistance – Function”). In this way, incorrect connec-
tion can be avoided and broken measurement cables
can be detected.
➭Connect the device under test to the +and COM jacks.
Wiring examples for the ESD measurement are included in sec-
tions 7.1 through 7.5.
Resistance can only be measured at voltage-free objects. If mains
voltage or interference voltage is applied to the measurement
inputs, measurement cannot be started.

Measurement Results
6.1 Discharging the Device Under Test
Attention!
!
If measurement is performed at a capacitive object such
as a long cable, it becomes charged with up to approx.
600 V!
Touching such objects is life endangering!
When a resistance measurement has been performed on a
capacitive object it is automatically discharged by the instrument
after measurement has been completed. Contact with the device
under test must be maintained to this end. The falling voltage
value can be observed at the U display.
Do not disconnect the DUT until less than 10 V is displayed for U!

6.6 Measurement with the GUARD Terminal
The measurement of very high resistances leads to extremely low
measuring current and may be rendered problematic as a result
of influences such as electromagnetic fields, humidity or surface
current. An accurate test set-up is thus absolutely essential.
A guard cable must be used for measurements within a range of
10 Gto 1 T, in order to prevent surface current from distorting
measurement results. The GUARD terminal at the measuring
electrode prevents current on the surface of the high-impedance
material to be measured from flowing from the + measurement
cable to the – measurement cable instead of through the high-
impedance material itself.
Ring Electrode according to IEC 61340-2-3
➭Connect the GUARD terminal at the measuring electrode to
the GUARD socket at the METRISO 3000 when measuring very
high-ohmic materials
The measuring sequence is the same as described in the previ-
ous sections.
7 Test Resistor for Resistance Measurement for
Checking the High Resistance Tester
It’s advisable to check the measuring instrument before, and if
necessary after use.
The two outermost jacks on the connection panel must be con-
nected to each other internally via a 10 Mtest resistor to this
end.
The sum of test resistor and cable resistance (for both cables),
including test probes, amounts to 10 M±5%. This value allows
for quick self-testing.
➭Connect the measurement cables to the +and COM jacks.
➭Insert the test probes into the above depicted jacks.
➭Within the RESD measuring function, use the rotary switch to
select desired measuring voltage UM: 10 V, 100 V or 500 V.
➭Press the start key and view the measurement results.

10.1 Creating ESD Control Elements, General
A complete structure with customer, building and ESD control
elements can be created in the METRISO 3000 test instrument. This
structure makes it possible to assign measurements to ESD con-
trol elements in various buildings and customer facilities.
There are two possible procedures:
Create a structure in the
test instrument.
A structure with up to
50,000 ESD control ele-
ments can be created in
the test instrument,
which is saved to the
instrument’s flash mem-
ory.
or
• Create and save an
image of an existing structure at a PC with the help of ETC
report generating software (Electric Testing Center) (see con-
densed operating instructions for ETC report generating soft-
ware). The structure is then transferred to the test instrument.
Note regarding ETC Report Generating Software
The following steps must be completed before using the soft-
ware:
• Install USB device drivers
(required for operation of the METRISO 3000 at a PC)
• Install ETC report generating software:
See information regarding ETC – Electric Testing Center.
(3-349-472-15)
10.2 Transferring Structures
The following data transfer operations are possible:
• Transfer a structure from the PC to the test instrument.
• Transfer a structure including measured values from the test
instrument to the PC.
The test instrument and
the PC must be con-
nected with a USB cable
in order to transfer struc-
tures and data.
The following image
appears at the display
during transfer of struc-
tures and data.
