Resistance Test Equipment
-
Check calibration date, inspect test probes, connect probes
- Fluke 85 Multimeter
- 1) Turn rotary switch four times to enable resistance testing
- 2) Check that display includes: "Auto", "0.L", and MΩ
- 3) Test resistance of material with probes
- Fluke is NOT SAFE for use around hazards
- Biddle Ohmmeter
- 1) Turn rotary switch to desired resistance range
- 2) Power on unit
- 3) Check condition of display battery by moving BAT.TEST toggle to DISPLAY
- 4) Check condition of measuring battery by moving BAT.TEST toggle to MEAS
- 5) Test resistance of material with probes
- Biddle is NOT SAFE for use around hazards
- Avtron T477W Ohmmeter
- 1) Push Test Pushbutton to turn unit on and set desired range
- 2) Test resistance of material with probes
- Avtron is safe for use except around EEDs
- HP 4328A Milliohmmeter
- 1) Check Condition of Battery by pushing and holding BATT.TEST pushbutton
- 2) Turn rotary switch to desired resistance range
- 3) Power ON unit with LINE toggle switch
- 4) Test resistance of material with probes
- HP is safe for use everywhere
- BCD M1 Ohmmeter
- 1) Power on meter with power button
- 2) Test resistance of material with probes
- BCD in NOT SAFE for use around hazards
-
Safety
- First, Turn off circuit power before measuring, Inspect probes for wear, Check meter for calibration date, Keep fingers behind finger guards
- Then, Which Ohmmeters are safe where?
- Around Electro-explosive devices (EED's)
- Hewlett Packard 4328A
- Around Fire, Combustion or Explosion hazards
- Avtron T477W, Hewlett Packard 4328A
- NOT safe around hazards
- Fluke 85, Biddle, BCD M1
