Prostat PAR-809C - Testing Analog Megohmmeter Performance

3. Rotate the PAR-809C’s Posion Selector knob to Posion 1, the lowest resistance reference.
4. Turn ON the PAR-809C’S posion indicang lights by sliding the  switch located on the
side of the instrument to the ON posion.
5. Insure the Foot Wear device under test is ON and funconal.
6. Using the second PAR-809C test lead with a metal alligator clip installed, press the push to 
 or plate on the Footwear tester.
a. The Foot Wear PASS or  indicaon should actuate upon contact with the PAR-
809C test lead alligator clip to the Foot Wear tester’s push to test buon or plate.
b. Note the reference resistance value and the response of the Foot Wear device under test.
7. Vary the PAR-809C reference resistance by rotang the Posion Selector Knob on the face of
the PAR-809C to the next posion and repeat step 6.
8. The resistance range posions where the device under test indicates PASS are those resistance
values accepted by the Foot Wear tester.
a. Resistance posions below the PASS range should all be rejected by the device under test
as too low.
b. Resistance posions above the PASS range should all be rejected by the device under test
as too high.
C. Conrming Resistance Measurement Performance of analog
Megohmmeters (Prostat PRS-800, 3-M-701 or similar)
1. Check the BATTERY funcon of the meter; replace bat-
teries if indicaon is .
2. Turn the meter to its  posion.
3. Install the meter test leads in the meter lead receptacles.
