general technology conditions, GB4793.1-1995 (IEC
61010-1, IEC 61010-2-032) electronic measurement
instrument safety requirements with secondary
pollution and over-voltage standard of CAT IV 600V
and CAT III 1000V.
Please follow the safety guidelines to ensure safe
usage of the meter. The meter will provide satisfactory
services to you if you use and protect it appropriately.
Warning
1.1 Preliminary
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 Please check for damage during transportation
after receiving the meter.
1.1.3 If the meter is stored and shipped under hard
conditions, please confirm if the meter is damaged.
1.1.4 Probe should be in good condition. Before use,
please check whether the probe insulation is
damaged and if the metal wire is bare.
1.2 Usage
1.2.1 When using, select the right function and
measuring range.
1.2.2 Don't measure by exceeding indication value
stated in each measuring range.
1.2.3 When measuring a circuit with the meter
connected, do not contact with 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 finger protection device
1.2.5 Do not measure voltage greater than AC 750V.
1.2.6 In the manual measuring range mode, when
measuring an unknown value, select the highest
measuring range first.
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 resistor, capacitor, diode and
circuit connected to power.
1.2.9 During the test of currents, resistors, capacitors,
diodes and circuit connections, be careful to avoid
connecting the meter to a voltage source.
1.2.10 Do not measure capacitance before capacitor is
discharged completely.
1.2.11 Do not use the meter in explosive gas, vapor or
dusty environments.
1.2.12 If you find any abnormal phenomena or failure
on the meter, stop using the meter.
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
level of performance.
