• The instrument may only be connected to a 230 V or 120 V
electrical system (depending on the country-specific design)
which is protected with a fuse or circuit breaker with a maximum nominal current rating of 16 A.
• Be prepared for the occurrence of unexpected voltages at devices under test (for example, capacitors may be dangerously
charged).
• Make sure that connector, measurement and test cables are
not damaged (i.e. broken insulation, kinks, interruptions etc.).
• Impulse withstand voltage of up to 2.5 kV may occur in
measurement category II systems with 230/400 V.
• If only the batteries are to be charged (instrument is ready for
operation in SETUP position), please ensure that the test instrument cannot be used by unauthorized personnel during
the charging process.
GMC-I Messtechnik GmbH9
• Measurement may only be performed on voltage-free equipment and devices.
• Measurements may not be performed under moist ambient
conditions, where condensation has occurred, or in explosive
atmospheres.
• Do not disconnect the measurement cables until the device
under test has been fully discharged.
• Observe accident prevention regulation (Health and Safety Policy DGUV regulation 3), “Electrical Systems and Equipment”.
• Do not perform measurements alone: always have a second
person help if possible.
• Make sure that measurement cables are connected correctly.
• Do not touch the test probes at any point beyond the finger
guard.
The METRISO PRIME+ may notbe used:
• If visible damage is apparent
• With damaged connector, measuring or test cables (test cables may not, under any circumstances, be mechanically damaged or kinked, because impaired insulation characteristics
may otherwise result)
• If these no longer function flawlessly
In such cases, the devices must be removed from service and
secured against any possible inadvertent use.
Send the instrument to our Repair and Replacement Parts service
department in such cases (see chapter 12 on page 54).
Opening of Equipment / Repair
Attention!
!
The equipment may be opened only by authorized service personnel to ensure the safe and correct operation of the equipment
and to keep the warranty valid. Even original spare parts may be
installed only by authorized service personnel.
In case the equipment was opened by unauthorized personnel,

2.1Checklist for High-Voltage Tests
Measurements may not be performed under moist ambient conditions, where condensation has occurred or in
explosive atmospheres.
Personnel Safety
➭ Turn the machine under test off and lock it in the off position.
➭ Perform insulation resistance measurement.
➭ Make sure that the system is grounded.
➭ Secure the danger zone with barriers, closing even narrow en-
trance ways.
➭ Set up warning signs such that they are plainly visible.
➭ Set up warning lamps such that they are plainly visible.
➭ Attach the emergency stop button in a plainly visible fashion.
➭ Warn personnel working in the area of possible danger.
➭ Always turn the test instrument off with the key switch and re-
move the key before leaving the work area.
10GMC-I Messtechnik GmbH
Safety Precautions for the Machine Under Test (recommended)
➭
Review the circuit diagrams and make a note of all electrical circuits.
➭ Disconnect the neutral conductor from the mains.
➭ Short circuit each electrical circuit to itself.
➭ Disconnect control circuits with overvoltage arresters, if the ar-
resters would be triggered by utilized test voltage.
➭ Disconnect PELV circuits (no high-voltage testing is required
for these circuits).
➭ Test insulation at each circuit with 1000 V.
(If insulation resistance is OK at 1000 V, no failures should
occur during the high-voltage test.)
➭ Disconnect frequency converters.
➭ Caution in TN systems!
The protective conductor is connected to the neutral conductor in the junction box. High-voltage is thus applied between
the phase conductors and the neutral conductor.
The neutral conductor must be cut if necessary, because it is
not disconnected from the mains by means of fuses.
Setting Up the Test Instrument
High-Voltage Test
➭
Test all circuits (conductors) against the protective conductor (all
switches in the mains circuit must be turned on, and testing must be
performed upstream and downstream from all relays and contactors).
➭ Remove all shorting devices after testing has been completed.
Testing Without Short-Circuiting
➭ Separately test all conductors from all circuits against the pro-
tective conductor (the machine could be damaged in the case
of arc-over).
Functions Test
➭ The machine must be tested for correct functioning after the
high-voltage test, especially as regards safety functions.

Each of the following tests is automatically assigned to one currently available object number. Any given test which is saved to
memory with the “STORE” key is stored with reference to this
number. The object number can be entered in the “DUT data”
menu (see chapter 5.1 on page 36).
Measuring mode operation is always carried out according to the following sequence:
• Select the desired test.
• Enter test parameters (if required).
• Start the measurement or return to the initial menu.
• Save measured values to memory and enter a description
(if desired).
Observe the following for all tests:
• Safety features and precautions, see chapter 2.
• Disconnect the device under test from all sources of voltage
first.
• Test for absence of voltage.
• Do not disconnect the measurement cables until the device
under test has been fully discharged.
4.1Insulation (resistance) Test
Test voltage can be set between 100 V and 5,000 V for this test.
This voltage, as well as the allowable limit value for insulation
resistance, can be selected as a test parameter.
Voltage at the device under test appears at the LCD in addition to
measured insulation resistance.
Discharge
After the measurement has been completed, the device under
test is discharged automatically in order to assure zero voltage.
The falling voltage value can be observed at the display during the
discharging process. The measured insulation resistance value
remains in memory during this period of time.
Interference Voltage
If voltage is present at the test probes after measurement is started, an “external voltage” warning
appears at the display. The level of the interference
voltage is shown at the display. The insulation test is aborted after
the test probes have been removed from the DUT. The test has to
be conducted again on the de-energized DUT.

2 minutes. This makes data logger operation possible for measuring durations between 2 and 60 minutes. In this case, the residual
time of the current measurement is not indicated in seconds, but
in minutes. While the test is being performed, icon “Stored” is
briefly shown in the display and the yellow signal lamp “Testing ...”
disappears briefly each time a measured value is being stored. If
the signal generator is activated, an acoustic signal sounds additionally.
In this function, the current test time is stored for each measurement instead of the parameter for the test duration to ensure the
temporal correlation between measured value and time of measurement.
Before the start of each test with data logger as
described in chapter 5.1, select a new device under test
to avoid the measured values being stored successively
within the same DUT.
This considerably facilitates the subsequent evaluation of
the stored measured values.

4.1.5 Measurements with the Guard Cable (feature G1)
Note
+Measurement Cable
–Measurement Cable
Guard Cable
Conductor
Insulation
Material
Guard Rings
Contact Ring
The measurement of very high resistances necessitates extremely
minimal 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
100 G (10 G) 1T, in order to prevent surface current from
distorting measurement results. The guard rings prevent current
at the surface of the insulation material from flowing from the
+measurement cable to the –measurement cable, instead of
through the insulation material itself.
➭ Insert the plug from the guard cable into the appropriate jack in
the test instrument.
➭ Plug the alligator clip onto the guard cable test probe.
➭ Connect the alligator clip to the guard ring between the two
measuring points at the insulation material under test.
➭ Refer to chapter 4.1.2 on page 25 regarding the measuring se-
quence
GMC-I Messtechnik GmbH27
The following materials can be used as guard rings: aluminum foil, copper foil or metallic hose clamps.
4.2Polarization Index Measurement
TEST
MENU
A polarization index test is recommended for electrical machines.
This procedure involves expanded testing of insulation resistance.
DC measuring voltage from the METRISO PRIME+ is applied to
the insulation for a duration of 10 minutes. Measured values are
documented after one minute, and after ten minutes. If the insulation is good, the value measured after ten minutes is higher than
the value measured after one minute. The relationship between
the two measurement values is the polarization index. Charged
material within the insulation is aligned due to the application of
measuring voltage over a long period of time, resulting in polarization. The polarization index indicates whether or not the charged
material contained in the insulation can still be moved, thus allowing for polarization. This, in turn, is an indication of the condition of
the insulation.
The following rules apply in general:
PI values < 1Troubleshooting is required.
PI values = 1 2Maintenance is recommended.
PI values = 2 4DUT is OK, no immediate action is
required. Preventive maintenance can be
planned according to the number of tests to
be performed.
PI values > 4DUT is in flawless condition.

4.5Voltage Measurement (protection against residual voltage)
Note
TEST
MENU
EN 60204 requires that voltages in excess of 60 V occurring at all
accessible machine components during operation must drop to a
residual voltage value of 60 V or less within a period of 5 seconds
after supply power has been switched off.
Testing for the absence of voltage is performed by means of a
voltage measurement which involves measuring discharge time
with the METRISO PRIME+. Elapsed time as of disconnection
from supply power is displayed continuously at the LCD during
discharge, until the limit value of 60 is reached.
In addition to voltage type (AC, DC or AC+DC), frequency is measured and displayed as well. The mean value is always read out.
In addition to voltage and frequency, voltage type (AC, DC or
AC+DC) appears at the symbol field in the display.
If voltage drops by more than 5% of the measured value during a
single measuring period (approx. 0.7 sec.) while performing a voltage measurement which results in a value of greater than 60 V, a
time measurement is started automatically in order to test protection against residual voltage. This time measurement can be
observed at the display in the symbol field. Time measurement is
stopped after voltage drops to below the limit value of 60 V. Time
required to discharge down to 60 V then appears at the display in
seconds. Voltage measurement continues until maximum allowable discharge time has elapsed (normally 5 seconds). The results
of the voltage measurement are then “frozen”, and the
DATA HOLD symbol appears at the display. If the 60 V limit value
is not reached before allowable discharge time has elapsed, the
voltage value is “frozen” and time measurement continues until
the 10 second time limit has elapsed. If voltage is still greater than
60 V after 10 seconds, the test is aborted and the instrument
restarts voltage measurement.
When the display is “frozen”, voltage measurement is not started
again until:
• The START key is pressed.
• The measured value is saved to memory by pressing the
i/Store key.
• Voltage measurement is restarted from the menu.
• Or voltage at the test probes climbs back up to a value of
greater than 60 V, or if the next measured value after a measurement of greater than 60 V is even higher, i.e. if a climbing
tendency can be observed.
Both elapsed time and the prevailing voltage value after allowable
discharge time has elapsed are saved to memory by pressing the
i/Store key. If no discharge takes place, only the voltage value is
saved.
If, for example, conductors are exposed when a machine
is switched off – e.g. if plug connectors are disengaged –
and if these are not protected against direct contact,
maximum allowable discharge time is 1 second!

48GMC-I Messtechnik GmbH
10.3Housing and Test Probes
No special maintenance is required. Keep outside surfaces clean
anddry. Use a slightly dampened cloth for cleaning. Avoid the use
of solvents, cleansers and abrasives.
Measurements may not be performed under moist ambient conditions, where condensation has occurred or in explosive atmospheres.
Prior to lengthy periods of rest (e. g. holiday), we recommend removing the (rechargeable) batteries. This helps to
prevent excessive depletion or leakage of batteries,
which, under unfavourable circumstances, may cause
damage to the instrument.
No condensation may be permitted to occur at the test
instrument, the test cables or the device under test,
because high-voltage may otherwise cause leakage current at the surfaces. Insulated components may also
conduct high-voltage in this case.
10.4Measurement Cables

10.6Recalibration
Pb Cd Hg
The respective measuring task and the stress to which your measuring instrument is subjected affect the ageing of the components and may result in deviations from the guaranteed accuracy.
If high measuring accuracy is required and the instrument is frequently used in field applications, combined with transport stress
and great temperature fluctuations, we recommend a relatively
short calibration interval of 1 year. If your measuring instrument is
mainly used in the laboratory and indoors without being exposed
to any major climatic or mechanical stress, a calibration interval of
2-3 years is usually sufficient.
During recalibration* in an accredited calibration laboratory
(DIN EN ISO/IEC 17025) the deviations of your instrument in relation to traceable standards are measured and documented. The
deviations determined in the process are used for correction of
the readings during subsequent application.
We are pleased to perform DAkkS or factory calibrations for you in
our calibration laboratory. Please visit our website at
www.gossenmetrawatt.com ( Company DAkkS Calibration
Center or FAQs Calibration questions and answers).
By having your measuring instrument calibrated regularly, you fulfill the requirements of a quality management system per
DINENISO9001.
* Verification of specifications or adjustment services are not part of the calibration.
For products from our factory, however, any necessary adjustment is frequently
performed and the observance of the relevant specification is confirmed.
