9 Product description
The digital multimeter (DMM) displays measurements on a digital 4000-count dis-
play (count = smallest display value). The display shows the correct terminal assign-
ment for each measurement mode. The multimeter beeps and displays a warning
when the terminals are not assigned correctly. This is a built-in safety feature to
protect the user.
The display also indicates the correct measurement terminals to use for each meas-
urement range.
The DMM can be used to take measurements up to CAT III 600 V. It is suitable for
use in hobby and professional applications.
It is not necessary to replace a triggered fuse for mA/µA current measurements.
The built-in PTC fuse restricts the current flow in the event of an overflow to protect
the multimeter and the circuit. The PTC fuse resets itself automatically after a short
cool-down phase, meaning that the current measurement circuit is only briefly inter
-
rupted.
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 battery and fuse compartment can only be opened when all test leads have
been disconnected from the multimeter. It is not possible to insert the test leads
into the terminals when the battery and fuse compartment is open. This is a built-in
safety feature designed to protect the user.
