DC Current Measurements
OBSERVE ALL SAFETY PRECAUTIONS AND WARNINGS
Operating Procedure
1. Turn the rotary selection switch to the current measurement function
A . Selection is confirmed with a short beep when exiting OFF.
2. Push and hold/DC zero.* Selection is confirmed with a short beep.
After 3 seconds, a second beep will confirm (ZERO). The display will
indicate dc 0.
3. Squeeze the trigger to open the jaws. Clamp the jaws around the con-
ductor. The most accurate readings are obtained with the conductor cen-
tered within the jaws.
4. Take the reading from the display. DC current measurements are pos-
sible from 300 mA to 1500.0 A.
*DC zero compensates for temperature variations and residual magnet-
ism in the transformer core. A beep will verify selection of DC zero. A sec-
ond confirmation beep will be heard when the display indicates dc 0.
