§
Cable resistance compensation ( zero) To measure low resistance values, measure the cable resistance first.
-Short-circuit the cables.
- Press and hold the HOLD key until zero appears on the display.The cable resistance value will then be
memorised and subtracted from the value of the resistance measured later.
Note : If the value measured is higher than 2 W , this correction is stopped and the memorised correction value is reset to
zero.
(1) with compensation for measurement cable resistance
MIN/ MAX Mode:
-Accuracy: same as previous table +0.2% L
-Capture time: 100 ms typ.
3.4 Resistance measurements (W , )
1. Connect the measurement cables to the unit terminals.
2. Set the rotary switch to position " " and press once on the yellow key: The symbol is no longer displayed.
3. Connect the unit to the circuit to be tested. Range selection is automatic. To measure low resistance with accuracy,
compensate the cable measurement resistance (see § 3.3). Above 40 W , the display indicates OL .

3.5 Semi-Conductor Test ( )
1. Connect the measurement leads to the instrument’s terminals, complying with the polarities indicated: red lead
on the “+” terminal and black lead on the “COM” terminal.
2. Set the rotary switch to " " position and press twice on the yellow key: The symbol is displayed.
3. Connect the unit to the semi-conductor (junction) to be tested.
The measurement current moves from the “+” terminals to the “COM” terminal. It corresponds to the direct
testing of the semi-conductor junction.
- Short-circuit junction: audio indication for a threshold <0.050V
- Cut or reversed junction (or threshold > 3.2 V) : OL displayed
