PMT-872A Wrist Strap/Footwear Auditor
E. TESTING THE HIGH END OF THE WRIST STRAPS “PASS” RANGE
Confi rm the toggle posi on is in the “Wrist Straps” posi on. Set the Variable Resistance Refer-
ence to 9.0x10 6 ohms. Using the metal banana plug end of the second reference lead, press the
PMT-872A’s “Push to Test” bu on and observe the instrument’s indica on LED lights. The following
PMT-872A indica ons should occur within approximately 1 second:
1. Ini ally, the HIGH FAIL and LOW BATT. LED’s should light briefl y.
2. The HIGH FAIL LED goes off , the PASS LED comes on and the LOW BATT. LED remains on.
3. The PASS LED remains on and the LOW BATT. LED goes off .
4. The audible BEEP begins to sound indica ng an acceptable resistance range.
F. TESTING THE WRIST STRAPS “ HIGH FAIL ” POINT
Confi rm the toggle posi on is in the “Wrist Straps” posi-
on. Set the Variable Resistance Reference to 1.05x10 7
ohms. Using the metal banana plug end of the second
reference lead, press the PMT-872A’s “Push to Test” but-
ton and observe the instrument’s indica on LED lights.
The following PMT-872A indica ons should occur within
approximately 1 second:
1. Ini ally, the HIGH FAIL and LOW BATT. LED’s should
light briefl y.
2. The HIGH FAIL LED remains on and the LOW BATT. LED goes off .
G. TESTING THE FOOTWEAR “LOW FAIL” POINT
Posi on the toggle switch DOWN , to the “Footwear: posi-
on, and set the Variable Resistance Reference to 7.75x10 5
Ohms. Using the metal banana plug end of the second
reference lead, press the PMT-872A’s “Push to Test” but-
ton and observe the instrument’s indica on LED lights.
The following three indica ons should take place within
approximately 1 second:
1. The PASS LED and the LOW BATT. LED come on.
2. The PASS LED goes off , the LOW FAIL LED comes on
and the LOW BATT. LED remains on.
3. The LOW FAIL LED remains on and the LOW BATT. LED goes off .
H. TESTING THE LOW END OF THE FOOTWEAR “PASS” RANGE
Set the Variable Resistance Reference to 1.1x10 6 ohms. Using the metal banana plug end of the
second reference lead, press the PMT-872A’s “Push to Test” bu on and observe the instrument’s
indica on LED lights. The following PMT-872A indica ons should occur within approximately 1
second:
