3.1. MEASUREMENT OF A VERY LOW VALUE
Reverse the direction of the current by pressing the ±I
key and the instrument displays the average:
R(+I) + R(-I)
2
This serves to eliminate any thermoelectric effect.
To display the values R(+I) and
R(-I), press the DISPLAY key.
R
AVG
=
In both cases, the last measurement
made is displayed, along with the
HOLD
symbol.
If the measurement is stopped by the
disconnection of a clip, simply connecting
it to another object starts another
measurement, with no need to press the
START/STOP key.
To display the voltage on the terminals of the resistance
instead of the measurement current, press the DISPLAY
key.
The energy accumulated in an inductive component when a measurement is made on it must be released.
You must never in any circumstances touch or disconnect the measurement leads until you have stopped making
the measurement and waited at least ten seconds for all of the energy in the item tested to be dissipated. Failure to observe
this precaution may result in the production of an arc, potentially hazardous for both the instrument and the operator.
