To avoid injury, when using the Clamp, ensure that
your fingers are behind the protective barrier as
shown in Figure 1.
Do not use the Clamp if any part, including the lead
and connector(s), appears to be damaged or if a
malfunction of the instrument is suspected.
Switch On
Switch the Clamp to the required current range, and check that
the LED is lit. The LED starts flashing when the battery voltage is
too low for normal operation and warns the user that it requires
changing. This procedure is described below.

Zero Adjustment

The output zero offset voltage of the Clamp may change due to
thermal shifts and other environmental conditions. To adjust the
output voltage to zero, depress the thumbwheel and rotate.
Ensure that the Clamp is away from the current carrying
conductor whilst the adjustment is made.
