•
Set the range selector at its highest position if the intensity of the
charge to be measured is unknown beforehand.
•
Disconnect the test leads from the tested circuit before rotating
the range selector in order to change functions.
•
When carrying out measurements on a TV set or switching power
circuits, always remember that the meter may be damaged by
any high amplitude voltage pulses at test points.
•
Always be careful when working with voltages above 60 VDC or
30 VAC rms. Keep your fingers behind the probe barriers at all
times during measurement.
•
Never perform resistance, diode or continuity measurements on
live circuits. Make sure all capacitors in the circuit are depleted.
6. General Description
Refer to the illustration on page 2 of this manual:
1. Illuminated LCD Display
2. /H button: slightly press this button to activate data hold function,
press again to exit data hold function. Hold and press this button to
activate LCD backlight function, press again to exit backlight function.
3. Rotary switch
"10A" jack
4.
Insert the red test lead in this connector in order to measure a max.
current of 10 A.
"VmA" jack
5.
Insert the red (positive) test lead in this connector to measure voltage
and resistance.
"COM" jack
6.
Insert the black (negative) test lead.
7. Overvoltage/Installation Category
DMMs are categorized depending on the risk and severity of transient
overvoltage that might occur at the point of test. Transients are short-lived
bursts of energy induced in a system, e.g. caused by lightning strike on a
power line.
