INSTRUMENT CHARACTERISTICS
Universal meter with TRUE RMS function and automatic range for each measurement. The meter not only
automatically selects the measuring range, but also independently recognises whether resistance, circuit
continuity, or DC or AC voltage is being tested at any given time. This makes the meter very easy to use.
With standard meters, the user needs to correct measuring range and type of measurement before the
measurement. With this meter, once switched on, all that needs to be done is apply the measurement probes
to the battery terminals, for example, and then read the result.
Before using the meter, read the instruction manual in its entirety and keep it for later use.
The meter has a plastic housing, liquid crystal display, and function keys. The housing is fi tted with measurement
jacks and an LED light. The meter is equipped with measurement cables.
The meter is sold without the batteries.
NOTE! This meter is not a measuring instrument within the meaning of the Trade Metrology Act.
