5.6 Measurement with the GUARD Terminal
The 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 GWto 1 TW, 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 METRISOâ2000 for the measurement of highly
resistive materials.

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 central
position 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 positioned
Adapter Z541A should not be exposed to intensive sunlight to prevent
inadvertent activation via infrared (battery life!).
