2.1 Battery Installation
Before changing batteries: set the switch to OFF and remove the clamp
from the circuit under measurement.
1.
Using a screwdriver, remove the battery compartment cover (1) from the
back of the housing (see Figure 3).
2.
Connect the battery to the snap-on connector (2), observing polarity.
3.
Place the battery into the battery compartment (3).
4.
Replace the battery compartment cover and screw it onto the housing.
2.2 External Power (Optional)
For long‑term measurements, you can connect the clamp to external power via any
micro‑USB adapter that delivers 100mA or more. If external power is disconnected,
the clamp automatically switches to battery operation.
The insulation between the type B micro‑USB connector and the measurement
output is 600V CAT III. This enables you to safely connect the clamp to measuring
instruments with uninsulated inputs. The type B micro‑USB connector must not be
in contact with conductors or uninsulated parts at dangerous voltage.
When operating on external power, the Auto Standby feature is disabled. The color
of the ON indicator shows whether automatic standby is enabled (green) or
disabled (yellow).
