61010-1, IEC 61010-2-032) electronic measurement
instrument safety requirements with secondary pollution
and over-voltage standard of CAT III 600V.
Please follow the safety operation guidelines to ensure
the safe use of meter.
The meter will provide satisfactory service to you if you
use and protect it appropriately.
Warning
1.1 Preparation
1.1.1 When using the meter, the user should comply with
standard safety rules:
- General shock protection
- Prevent misusing the meter
1.1.2 After receiving the meter, please check for damage
that may have occurred during transportation.
1.1.3 If the meter is stored and shipped under hard
conditions, please confirm that the meter is
undamaged.
1.1.4 Probe should be in good condition. Before use,
please check whether the probe insulation is
damaged, whether metal wire is bare.
1.1.5 Use the probe table provided with the meter to
ensure safety. If necessary, replace the probe
with another identical probe or one with the same
specification.
1.2.1 When using the meter, select the right function
and measuring range.
1.2.2 Don't measure when exceeding the maximum
value in each measuring range.
1.2.3 When measuring a circuit with the meter
connected, do not touch the probe tip (metal part).
1.2.4 When measuring, if the voltage to be measured
is more than 60 V DC or 30 V AC (RMS), always
keep your fingers behind the finger protection
device.
1.2.5 Do not measure voltage greater than AC 600V.
1.2.6 In the manual measuring range, when the value
to be measured is not known in advance, choose
the highest measuring range to begin, and then
gradually select lower ranges until the correct
range is identified.
1.2.7 Before rotating conversion switch to change
measuring function, remove probe from the
circuit to be measured.
1.2.8 Don't measure resistors, capacitors, diodes and
circuits that are energized.
1.2.9 During the test of current, resistors, capacitors,
diodes and circuit connections, do not allow the
meter to connect with voltage source.
