W Warning
Due to the high measuring current inductive loads can
cause lethal induced voltages during disconnection from
the measuring circuit.
4. Start measurement with "START TEST" button. First, "R1" with
positive voltage is measured on jack "E". After releasing the "START
TEST" button "R
2
" is measured with negative voltage on jack "E".
The respectively higher measured value is displayed first.
5. The second measured value can be called with "DISPLAY MENU".
If the set limit value (R LIMIT) is exceeded the limit can also be dis-
played.
Evaluation of measured value:
Taking into account the maximum operating error, the diagrams show the
maximum admissable display values to be displayed so not to exceed the re-
quired resistance.
Measuring Range 29, 99 ... 299, 9 ... 2999 Ω

Compensation of Measuring Lead Resistance
1. Call display of R
K
with button "DISPLAY MENU".
2. Short circuit measuring lead according to picture.
3. Press "START TEST" button. Value R
K
is stored after the release of
the "START TEST" button, the display jumps back to voltage meas-
urement. Thereafter, R
K
is subtracted from the actual measured value.
