SAFETY INFORMATION
RULES FOR SAFE OPERATION
Warning
To avoid possible electric shock or personal injury, and to avoid possible damage to the
Meter or to the equipment under test, adhere to the following rules:
● Before using the Meter inspect the case. Do not use the Meter if it is damaged or the
case (or part of the case) is removed. Look for cracks or missing plastic. Pay attention
to the insulation around the connectors.
● Inspect the test leads for damaged insulation or exposed metal. Check the test
leads for continuity. Replace damaged test leads with identical model number or electri-
cal specifications before using the Meter.
● Do not apply more than the rated voltage, as marked on the Meter, between the
terminals or between any terminal and grounding. If the value to be measured is
unknown, use the maximum measurement position and reduce the range step by step
until a satisfactory reading is obtained.
● When measurement has been completed, disconnect the connection between the
test leads and the circuit under test, remove the testing leads away from the input
terminals of the Meter and turn the Meter power off.
● The rotary switch should be placed in the right position and no any changeover of
range shall be made during measurement is conducted to prevent damage of the
Meter.
