1.1. Preliminary
WARNING
Be extremely careful when using this meter. Improper use of this device can result in electric
shock or destruction of the meter. Take all normal safety precautions and follow the safeguards
suggested in this manual. To exploit full functionality of the meter and ensure safe operation,
please read carefully and follow the indications in this manual. If the equipment is used in a
manner not specified by the manufacturer, the protection provided by the equipment may be
impaired.
This meter is designed and manufactured according to safety requirements of EN 61010-1, EN
61010-2-032, EN 61010-2-033 concerning electronic measuring instruments with a measurement
CAT III 1000V, CAT IV 600V and pollution degree 2 and safety requirements for hand-held clamps
for electrical measurement and test.
• When using the meter, the user should comply with standards safety rules:
-
General shock protection
-
Prevent misusing the meter
• Please check for damage during the transportation after receiving the meter.
• If the meter is stored and shipped under hard conditions, please confirm if the meter is damaged.
• Probe shuld be in good conditions. Before use, please check whether the probe insulation is
damaged and if the metal wire is bare.
• 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.
1.2. Usage
• When using, select the right function and measuring range.
• Don´t measure by exceeding indication value stated in each measuring range.
• When measuring a circuit with the meter connected, do not contact with probe tip (metal part).
• When measuring, if the voltage to be measured is more than 60VDC or 30VAC (TRMS), always
keep your fingers behind finger protection device
• Do not measure voltage greater than AC 750.
• In the manual measuring range mode, when measuring an unknown value, select the highest
measuring range first.
• Before rotating conversion switch to change measuring function, remove probe from the circuit to
be measured.
• Don´t mesure resistor, diode and circuit connected to power.
• During the test of currents, resistors, diodes and circuit continuity, be careful to avoid connecting
the meter to a voltage source.
• Do not use the meter in explosive gas, vapor or dusty enviroments.
• If you find any abnormal phenomena or failure on the meter, stop using the meter.
• Unless the meter bottom case and the battery cover are completely fastened, do not use the meter.
