switch the measuring range to the maximum position.
• Input value can’t exceed the input limit specified in each measuring range to
prevent damage to the meter.
•
When the meter is connected to the circuit being measured, do not touch
the unused input end.
• When the voltage to be tested exceeds 60Vdc or 30Vac effective value,
please operate carefully to prevent electric shock.
• When use the test probe to measure, you should place your fingers at the
back of retaining ring.
• When you measure with test probe, first connect the common testing end of
black test probe to the common testing end of circuit to be tested, then con
-
nect red test leads to the test circuit of the test probe to the test end of circuit
to be tested. When the measurement is completed, you should first remove
the red test probe, then remove the black common test probe.
•
Before changing the measuring range, you must ensure that the test probe
is not connected tocircuit to be tested.
• For all DC functions, including manual or automatic measuring range, to
avoid the risk of electric shock due to possible incorrect readings, please use
AC function to verify the existence of any AC voltage.
•
Then, select DC voltage measuring range equal to or greater than the AC
measuring range.
•
Before testing resistance, diode, capacitance measurement or on-off states,
you should first cut off power to the circuit being tested, and discharge all
high voltage capacitors.
• Don’t measure resistance or make on-off tests on a live circuit. .
• Before current measurement, you should firstly check the meter’s fuse. Be
-
fore the meter is connected to the circuit under testing, you should firstly
power off the circuit to be tested.
• When you make TV repairs or measure power conversion circuits, you
should note the high amplitude voltage pulse of circuits being tested.
• The TV filter should be used to weaken these pulses to avoid the meter
damage.
• This meter uses a 9V 6F22 battery. The battery should be properly installed
in the meter’s battery compartment.
