NOTE: Before changing the battery, set the switch to OFF and remove the

clamp from the circuit being measured.

Using a screwdriver, remove the battery compartment cover (1) from the

back of the housing (see Figure 3).

Connect the battery to the snap-on connector (2), observing polarity.

Place the battery into the battery compartment (3).

Replace the battery compartment cover and screw it onto the housing.

For long-term measurements, you can connect the clamp to external power via any

micro-USB adapter that delivers 100 mA 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 600 V 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 the automatic standby is enabled (green) or

disabled (yellow).
