Mastech MS2016A Operation Manual page 3

Probe should be in good condition. Before use, please
1.1.4
check whether the probe insulation is damaged and if
the metal wire is bare.
Use the probe table provided with the meter to ensure
1.1.5
safety. If necessary, replace the probe with another
identical probe or one with the same level ofperformance.
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 VAC (RMS), always keep
your fingers behind finger protection device.
1.2.5 Do not measure voltage greater than 600V DC or
AC(RMS).
1.2.6 In the manual measuring range mode, when measur-
ing 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.
During the test of currents, resistors, capacitors, diodes
1.2.9
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.
