(1) Transformer Jaws
Pick up the AC current or DC current flowing through the
conductor. The "-" marking on the jaw indicates direction of
DC current existing on the conductor being tested which
follows forward and vertically with jaws, the reading shown
on display is positive.
(2) Barrier
Provide a protective distance from hands to conductor.
(3) Jaw Trigger
Press the lever to open the transformer jaws.
When the lever is released, the jaws will close again.
(4) Function selector rotary switch
The rotary switch selects the function.
(5) LCD Display
The LCD display indicates the function mode, bar graph,
annunciator, and measured value of a signal. Field effects
3¾ digit LCD with maximum reading of 3999.
(6) Volt/Ohm/Frequency Terminal
This is positive input terminal for voltage / ohm /
frequency measurement. Use the RED test lead to connect.
(7) COM Terminal
This is the ground input terminal. Use the BLACK test lead
to connect.
