Fluke 1625 Compensation of Measuring Lead Resistance, W Warning, Evaluation of measured value

Users Manual

WWarning

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 "R2" 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 RK with button "DISPLAY MENU".

2.Short circuit measuring lead according to picture.

3.Press "START TEST" button. Value RK is stored after the release of the "START TEST" button, the display jumps back to voltage meas- urement. Thereafter, RK is subtracted from the actual measured value.
