➭ Select the RESD menu and a test voltage of UM = 10 volts. If a value of less than 100 k� is displayed, the measured value is the result.



5.6 Measurement with the GUARD TerminalThe measurement of high-value resistance necessitates extremely small measuring current and may be rendered problematic by influences such as electromagnetic fields, humidity or surface current. A precise test setup is therefore absolutely essential.For measurements within a range of 10 G� to 1 T�, a guard cable must be used to prevent surface current from distorting measurement results. The GUARD terminal at the measuring probe prevents current at the sur-face of a highly resistive test object from flowing from the + measurement cable to the - measurement cable, instead of through the highly resistive material itself.

Ring Probe in compliance with IEC 61340-5-1 / DIN EN 61340-5-1

➭ Connect the GUARD terminal at the measuring probe to the GUARD jack at the METRISO�2000 for the measurement of highly resistive materials.

8 Measuring Alternating VoltageSinusoidal alternating voltage within a frequency range of 15 to 400 Hz can be measured with the test instrument.

➭ Press the U~/f key.➭ Contact the measuring points with the measuring probes.

Notes• The voltage measuring range has an overload capacity of 1200 V.• The input impedance for the voltage measuring range is 5 M��

9 Measuring Temperature and Humidity with Adapter Z541A

Temperatures within a range of –10.0 C to +50.0 C, as well as relative humidity from 10.0% to 90.0% can be measured with the temper-ature-humidity combination adapter.➭ Connect the temperature-humidity adapter to the IR interface of the

test instrument (see drawing on page 2) by inserting the guide pin of the adapter in the opening provided at the top of the test instrument such that the adapter is located on the two rubber pads in centralposition to the housing. Then push the adapter down to fix it tightly.

➭ Press the T/R.H. key. The adapter is activated via the interface.➭ Select the desired temperature unit of measure, C or F, with the

corresponding key. Temperature and humidity are displayed directly.➭ We recommend moving the test instrument with the adapter for a few

seconds to enable the adapter to adjust to the prevailing room climate more quickly. The air current can thus penetrate through the opening into the adapter housing more quickly. It would otherwise take several minutes to achieve this condition.

➭ When changing to another function, the adapter is deactivated.➭ The measured values are only updated every 5 seconds to extend the

service life of the batteries in the adapter.Display at the Test Instrument

The „— — —“ symbol shown on the display can be attributed to the fol-lowing causes:– Exposure to intense direct sunlight– depleted batteries in adapter Z541A– adapter defective or not properly positionedAdapter Z541A should not be exposed to intensive sunlight to prevent inadvertent activation via infrared (battery life!).

12 Maintenance

12.1 Self-Test

➭ The self-test is started from the main menu with the Test key. The test has a duration of several seconds.

The following information is displayed in the two headers:Type/Cal: Device type / date of last calibrationVersion: Software version and issue date

Self-tests for the items Chksum through LED are performed automatically, one after the other, and are checked off or marked with a horizontal dash if they are not passed.

Chksum1/2: Status display for internal testing (Each test must be completed with a check mark. If not, the measuring and test instrument may no longer be used. Please contact our service center in this case.)

Relays: Each relay is switched twice.LED: The U, LIMIT and NETZ/MAINS lamps each blink twice in red.

The PE lamp cannot be tested automatically!As soon as the tests in the left-hand column have been completed, the following tests must be started manually:


➭ Illum: Press the Test key twice in order to activate and deactivate display illumination.

➭ Display: Press the Test key after each test pattern appears in order to check the display elements.

➭ Keytest: Perform the key test by pressing each of the softkeys once, and by pressing the start key once in each of its three positions. The keys appear filled in at the key pictograph after they have been tested.

Individual tests can be skipped by pressing the skip key before starting the respective test. These tests are then identified with a horizontal dash, as is also the case for tests which have not been passed.

12.2 Battery OperationWhen only one solid segment remains in the battery symbol, the batteries must be replaced, or recharged if rechargeable batteries are used.Check the batteries at short, regular intervals or after lengthy periods of storage to make sure no leakage has occurred. If leakage has occurred, the electrolyte must be carefully and completely removed from the instrument with a damp cloth before new batteries are installed.

Charging the Batteries

Attention!!Use only the NA 0100S battery charger (article no. 7100.2000.MK.Z501D) with safe electrical isolation and a nominal secondary voltage of 9 V DC to recharge the batteries. Before connecting the battery charger to the charging socket at the device, make sure of the following points:– Rechargeable batteries have been installed (not normal batteries).– The instrument has been disconnected from the measuring

circuit at all poles.– The voltage selector at the charger has been set to 9 V.

Connect the NA 0100S battery charger to the charging socket with the 3.5 mm jack plug. Set the voltage selector switch at the NA 0100S to 9 V. Switch the test instrument on.The test instrument recognizes the fact that a battery charger has been connected and starts the charging cycle. The 5 segments of the battery symbol are continuously displayed in a sweeping pattern from left to right for the entire duration of the charging cycle.Depleted batteries require a charging cycle of approximately 14 hours. If the batteries are exhausted to a great enough extent, the test instrument can no longer be switched on. If this is the case, leave the test instrument connected to the activated battery charger for about 30 minutes, and then proceed as described above.

12.3 Changing the Batteries of the Temperature and Humidity MeasuringAdapter Z541A

Separate the bottom part of the housing from the top to change the bat-teries.➭ Untighten the screw at the bottom of the housing and remove the

housing lid.➭ Insert two 1,5 V round cells of type LR1 (size N) in the battery com-

partment according to the indicated polarity symbols.➭ Replace the housing lid (the opening at the bottom of the housing and

the thread of the screw must be on top of each other) and press the lid until it engages. Retighten the screw carefully.

12.4 HousingNo special maintenance is required for the housing. Keep outside surfaces clean. Use a slightly dampened cloth for cleaning. Avoid the use of cleansers, abrasives and solvents.
