3. Once the cable and BNC adapter are installed the PRF-922B is ready for con nuity test, veri fi ca-
on and use (Figure 4).
4. To use, connect dual banana converter to wide range, resistance instrument with ¾ inch termi-
nal spacing. Flange side of dual banana should be connected to the Posi ve (+) power terminal.
NOTE
To remove BNC connec ons, apply slight pressure and twist connector counter clockwise
B. Con fi rming Proper BNC Connec ons, Con nuity & High Resistance Tests
The following con fi rms proper connec ons by checking con nuity of the micro probe against a
metal plate, then con fi rms its ability to measure high resistance.
1. To con fi rm general setup and func on of the PRF-922B, place the electrodes against a clean
metal surface. For example, the plated metal side of the Prostat PTB-920, Dual Surface Test
Bed.
a. Hold the PRF-922B ver cally, and apply pressure to slightly compress the electrodes, mak-
ing posi ve contact with the metal surface.
b. Ac vate the wide range, resistance instrument to obtain a measurement.
(1) In the case where the Prostat PRS-801 is the measurement instrument, it should
measure approximately 1.0 ohm, or less.
(2) With other instruments, they should provide a LOW resistance indica on. For
example, <10 3 ohms when using the ESD Check ESI-870 Resistance Indicator, or <10 4
ohms when using the PRS-801 Resistance Meter.
2. Repeat the above procedure using the clean insulated surface (Black, labeled side) of the PTB-
920, or an insulated acrylic plate.
