RESISTANCE / CONTINUITYMEASUREMENT
CAUTION: Make sure that power is removed and all
capacitors have been discharged before measuring.
1) Set the rotary switch to "TEMP.

2) Insert the black test lead to "COM" terminal and red test lead to
" V -

3) Short the test leads together and momentarily press the ZERO button to subtract
test lead resistance from measurement.
4) Touch the test leads to the circuit (Fuse Cartridge or other) and read resistance
value in the display.
5) Press

.
7) OL (overload) is displayed if the resistance across the input terminals is greater
than the full-scale rating on the range setting of the instrument. Be sure that the
contact between the probes and the circuit is clean. Dirt, oil, paint, rust or other for-
eign matter can seriously effect resistance measurements.
