The mA/µA measurement input is equipped with a maintenance-free self-resetting
PTC fuse and one ceramic tube fuse, which can be used in the case of conventional
overload mis-operation of less than about 5A, the current is limited and the meter
is well protected. When the meter is being used for mA/µA measurement, but the
meter is mistakenly connected to a high-energy high-voltage power supply, then the
ceramic tube fuse will work and probably blow to protect the meter. In such case, the
blown ceramic tube fuse is required to be replaced by a new one.
The multimeter is powered by standard 3x AAA 1.5 V batteries. The current clamp
requires two standard micro batteries (AAA, LR3 or equivalent). The device may
only be operated with the specified batteries. Due to their low capacity and partly
lower cell voltage, rechargeable batteries should not be used.
The device switches off automatically after 15 minutes if no buttons are pressed.
This prevents the battery from draining. The automatic shut-off function can be disa-
bled.
There is a fold-out stand on the rear of the device. This allows the multimeter to be
positioned for optimum readability.
Do not use the multimeter and current clamp when the battery compartment is open
or when the battery compartment cover is missing.
Do not take measurements in potentially explosive areas, damp rooms or adverse
conditions. Adverse conditions include: Moisture or high humidity, dust and flam
-
mable gases, vapours or solvents, thunderstorms and strong electromagnetic fields.
For safety reasons, only use test leads or accessories that match the multimeter’s
specifications.
The multimeter may only be used by people who are familiar with the relevant regu-
lations and understand the potential hazards. The use of personal protective equip-
ment is recommended.
