1.2 During use
1.2.1 Never exceed the protection limit values indicated in
specifications for each range of measurement.
1.2.2 When the meter is linked to a measurement circuit, do
not touch unused terminals.
1.2.3 Do not measure voltage if the voltage on the
terminals exceeds 600V above earth ground.
1.2.4 Always be careful when working with voltages above
60V DC or 30V AC rms, keep fingers behind the probe
barriers while measuring.
1.2.5 Never connect the meter leads across a voltage
source while the function switch is in the current,
resistance, diode or continuity mode. Doing so can
damage the meter.
1.2.6 Before stir the transform switch to change functions,
disconnect test leads from the circuit under test.
1.2.7 When carrying out measurements on TV or
switching power circuits always remember that there
may be high amplitude voltages pulses at test points,
which can damage the meter.
1.2.8 Never perform resistance measurements on live
circuits.
1.2.9 If any faults or abnormalities are observed, the
meter can not be used any more and it has to be
checked out.
1.2.10 Never use the meter unless the rear case is in
place and fastened fully.
1.2.11 Please do not store or use meter in areas
exposed to direct sunlight, high temperature,
humidity or condensation.

Operating instruction
4.1 Data hold(HOLD)
If you need data hold when measuring, you can put on
“HOLD”; it will hold the reading; if you put the button again,
data hold is not continue.
4.2 Manual range(RANGE)
Press this key to switch the range to manual state.
Long press this key to restore the automatic range
state
4.3 Switch function(SELECT)
Press this key to achieve ac and dc current switching and
resistance - diode - short circuit/break function switching
4.4 Auto power off
If no operation within fifteen minutes after power is on,
meter will auto power off with five short sounds and one
long.
After auto power off, if stir the transform switch or
putdown any button of "HOLD”, “RANGE”, “SELECT”,
meter will recover the working condition.

4.5 Preparation for measurement
4.
5.1 Stir the transform switch. If the battery voltage is less
than 2.4V, display will show “ ”, the battery should be
changed at this time.
4.5.2 The “ ” besides the input lead shows that the input
voltage or current should be less than specification on the
sticker of the meter to protect the inner circuit from
damaging.
4.5.3 Select a transform switch accordingly for the item to
be measured.
4.6 Measuring ac voltage
4.6.1 Set the transform switch at the AC V range position.
4.6.2 Connect test leads across the source or load under
measurement.
4.6.3 You can get reading from LCD.
NOTE:
“ ” means you can’t input the voltage which more
than 600V DC or 600V rms AC, it’s possible to show
higher voltage, but it’s may destroy the inner circuit.
Pay attention not to get an electric shock when
measuring high voltage.

Operating instruction
4.1 Data hold(HOLD)
If you need data hold when measuring, you can put on
“HOLD”; it will hold the reading; if you put the button again,
data hold is not continue.
4.2 Manual range(RANGE)
Press this key to switch the range to manual state.
Long press this key to restore the automatic range
state
4.3 Switch function(SELECT)
Press this key to achieve ac and dc current switching and
resistance - diode - short circuit/break function switching
4.4 Auto power off
If no operation within fifteen minutes after power is on,
meter will auto power off with five short sounds and one
long.
After auto power off, if stir the transform switch or
putdown any button of "HOLD”, “RANGE”, “SELECT”,
meter will recover the working condition.

than 2.4V, display will show “ ”, the battery should be
changed at this time.
4.5.2 The “ ” besides the input lead shows that the input
voltage or current should be less than specification on the
sticker of the meter to protect the inner circuit from
damaging.
4.5.3 Select a transform switch accordingly for the item to
be measured.

NOTE:
“ ” means you can’t input the voltage which more
than 600V DC or 600V rms AC, it’s possible to show
higher voltage, but it’s may destroy the inner circuit.
Pay attention not to get an electric shock when
measuring high voltage.
4.7 Measuring dc voltage
4. 7.1 Set the transform switch at the DC V range position.
4.7.2 Connect test leads across the source or load under

4.8 Measuring resistance
4.8.1 Set the transform switch at the desired range.
4.8.2 Connect test leads across the resistance under
measurement.
4.8.3 You can get reading from LCD.
NOTE:
For measuring resistance above 1M, the meter may
take a few seconds to get stable reading.
When the input is not connected, i.e. at open circuit, the
figure ‘OL’ will be displayed for the overrange condition.
When checking in-circuit resistance, be sure the
circuit under test has all power removed and that all
capacitors have been discharged fully.
4.9 Measuring capacitance(for 9216)
4.9.1 Set the transform switch at the range position.
4.9.2 Connect test leads across the capacitance under
measurement.
4.9.3 You can get reading from LCD.
Warning
To avoid electric shock, be sure the capacitors have been
discharged fully before measuring the capacitance of a
capacitor.

NOTE:
It takes certain time (200μF range 30 seconds) to
steady the reading when measuring high capacity.
4.10 Measuring frequency
4.10.1 Set the transform switch at the Hz range position
4.10.2 Connect test leads across the source or load
under measurement.
4.10.3 You can get reading from LCD.
4.11 Testing diode
4.11.1 Set the transform switch at the range position.
4.11.2 Connect the red lead to the anode, the black lead to
the cathode of the diode under testing.
4.11.3 You can get reading from LCD.
NOTE:
1.The meter will show the approximate forward voltage
drop of the diode.
2.If the lead connection is reversed, only figure‘0L’will be
displayed.
4.12 Continuity test
4.12.1 Set the transform switch at the range position.
4.12.2 Connect test leads across two points of the
circuit under testing.
4.12.3 If continuity exists（i.e., resistance less than
about 50Ω）, built-in buzzer will sound.
4.12.4 You can get reading from LCD.
NOTE:
If the input open circuit(or the circuit resistance measured
is higher than 400Ω), then the figure‘0L’ will be displayed.
