CLAMP INSPECTION and MAINTANENCE
IMPORTANT: Both jaws of each clamp must rmly engage terminals.
The copper jaw contains
the smaller gauge wire that
reads the voltage and the
silver jaw contains the larger
conducting wire that draws
the load in each test. Jaw
insulation is necessary for
accurate readings. Damaged
clamps or loose wires will
affect the readings. Keep
clamps clean and in good
repair.
CHECK OFTEN FOR LOOSE JAWS
OR DAMAGED INTERNAL PLASTIC
SHOULDER INSULATORS
