5. Measurement operation
5-1 DC & AC voltage measurement
Warning:
To avoid harms to you or damage to the meter from
electric shock. Please do not attempt to measure
voltage higher than DC/AC 1000V although readings
may be obtained.
The DC voltage range are 200.0mV, 2.000V, 20.00V ,
9
Page 12
200.0V and 600V and then. The AC voltage ranges are
2.000V, 20.00V, 200.0V and 600V.
To measure DC or AC voltage:
④ Insert the red test lead into the ‡ VΩ· input terminal
and the black test lead into the COM terminal.
⑤ Set the rotary switch to DC or AC range.
⑥ Connect the test lead across with the object under
testing.
The measured value will be show on the LCD
display.
Note:
When DC or AC voltage measurement has been completed,
disconnect the connection between the testing lead and the
circuit under testing.
5-2. Resistance measurement
The resistance range are: 200.0έ , 2.000Kέ ,20.00Kέ ,
200.0Kέ , 2.000Mέ .20.00Mέ .
To measure resistance, connect the meter as follows:
④ Insert the red test lead into the · VΩ· terminal and
the black test lead into the COM terminal.
⑤ Set the rotary switch to proper resistance range..
⑥ Connect the test lead across with the object under
testing.
The measured value will be show on the LCD display.
Note:
◤ The test lead can add 0.1 έ to 0.2 έ of error to
resistance measurement. To obtain precision reading
in low-resistance measurement, that is the range of
200.0έ , short the input terminal before measuring.
In this time, the contact resistance displayed on the
LCD. You can subtract the contact resistance value
from the measured value.
Page 13
◤ For high-resistance measurement (>10M έ ), it is
normal taking several second to obtain stable
reading.
◤ The LCD display ‡ OL· indicating open-circuit for the
tested resistor or the resistor value is higher than the
maximum range of the meter.
5-3. Diode/Continuity check
5.3.1. Diode
④ Set the rotary switch to ‡ · position. First time,
default mode is diode check mode. You can enter the
continuity check mode by the ‡ FUNC· Key.
⑤ insert the red test lead into the “VΩ” terminal and the
black test lead into the ‡ COM· terminal.
⑥ Use the diode test mode to check diodes, transistors
and other semiconductor device. In the diode test
mode sends a current through the semiconductor
junction, and the measure the voltage drop across the
junction. A good silicon junction drop between 0.5V
and 0.8V.
⑦ For forward voltage drop reading on any
semiconductor component, place the red test lead on
the component anode and place the black test lead on
the component cathode. The measured value show on
the display.
⑧ Reverse the test lead and measure the voltage across
the diode again.
◤ If diode is good, the display shows ‡ OL· .
◤ If diode is shorted, the display shows 0 in both
direction.
◤ If display shows ‡ OL· in both direction, the diode
is open.
5.3.2. Continuity Check:
10
Page 14
④ Press the ‡ FUNC· key to enter to the continuity mode.
⑤ The buzzer sound if the resistance of a circuit under
test is less than 100έ .
5-4. DC/AC µA or mA measurement
DC Current range is 200.0¸ A/2000¸ A and
20.00mA,/200.0mA and then 10A range.
AC Current range is 200.0¸ A/2000¸ A and
20.00mA,/200.0mA and then 10A range.
④ Turn off power to the circuit. Set the rotary switch
to the proper DC/AC ¸ A or DC/AC mA position.
⑤ Break the current path to be tested. Connect the
red test lead to the more positive side of the break
and the black test lead to the more negative side of
the break.
⑥ Turn on power to the circuit. The measured value
show on the display.
5-5. DC/AC 10A measurement
④ Insert the red test lead into the input terminal
marked as ‡ 10A· .
⑤ The measuring procedure is same as that of 5-4
section..
Note:
◤ For safety”s sake, the measuring time for high current
should be ≧ 10 second for each measurement and the
interval time between two measurement should be
greater than 5 minutes.
◤ When current measurement has been completed,
disconnect the connection between the testing lead and
the circuit under test.
5-6. Temperature measurement
To measuring temperature should be use the K-type
11
Page 15
probe :P3400.
④ Set the rotary switch to the ‡ TEMP· range. In this
time, The environment temperature value displayed
on the LCD.
⑤ Insert the K-type probe to the two ‡ COM· and
‡ TEMP· terminals. The two ‡ +· and ‡ -‡ pins of
temperature probe(P3400) must be direct at the
‡ COM· & ‡ ₤ · terminal respectively.
⑥ The measured temperature value will be displayed on
the LCD.
6. Maintenance
6-1. Replacing the battery
When meter display the battery must be replace
to maintain normal operation.
④ Disconnect and remove all test probes from any live
source and meter.
⑤ Open the battery cover on the bottom case by
screwdriver.
⑥ Remove old battery and snap new one into battery
holder
6-2. Fuse replacement
Replacing the defective fuse should the done
according to the following procedure.
④ To avoid electrical shock, remove the test lead and
any input signal before opening the bottom case.
⑤ Open the button case and then remove the
defective fuse and insert a new fuse of the same size
and rating.
⑥ Replace the bottom case and reinstall all the screw.
6-3.Cleaning and Decontamination
The meter can be cleaned with soft clean cloth to remove
1213

any oil, grease or grim. Do not use liquid solvent or
detergent.
