with Green PASS light, Red LOW and HIGH Fail lights, and yellow ba ery
low indicator. Connec ons are provided for an op onal AC/DC Power

pre-set resistance range.
2. PASS (Green LED Light) and an Audible Buzzer indicates the object is within the acceptable pre-
set resistance range.
3. LOW FAIL (Bo om RED LED light) indicates that the object being tested is less than the accept-
able pre-set resistance range.
B. The PMT-872A self-test sequence is ac vated each me the unit is used. Upon comple on of an
acceptable self-test and ba ery check, the unit’s Yellow “Low Ba .” LED Light will go off .
C. The PMT-872A pre-set resistance measurement ranges for wrist straps and footwear are as fol-
