Safety Warnings
The design, manufacturing and test of this meter all meet

-2-
the safety standard requirements of IEC61010-1. The manual
contains the warnings and safety rules that users must comply
with to ensure the safe use of the meter and its safe status. Please
read the following instructions before use.
Warning
Do not use a damaged meter. Before using the meter,
please check its enclosure to see if there is any crack,
missing plastic part or if its outer protective cover is in
place. Please pay special attention to the insulation layer of
the joints.
Please make sure that the battery cover is locked tightly
before using the meter.
Please remove the test leads from the meter before opening
the battery cover.
Check the test lead to see if its insulation has any damage
or it has any exposed part. Check the connectivity of the
test leads. If the lead is damaged, please replace it before
using the meter.
If the meter malfunctions, it means that the protection
could have been damaged, so please do not use it. If there
is any doubt, the meter should be sent for maintenance.
Do not use the meter near explosive gases, steam or dust.
The meter only uses LR03/AAA batteries, so please make
sure the battery is correctly installed.
When using a test probe, the finger should hold the back of
the probe's protective layer.
When connecting wires, connect the common test leads
first, and then connect the live test leads. When
dismantling, remove the live test lead first.
Please carefully read and understand the manual before
using the meter.
The requirements of the manual must be complied with at
any time, and the manual should be well kept to ensure it

-3-
available for reference at any time.
During the meter test, incorrect operation may lead to
accident and damage to the meter.
Cautions
To prevent damage to the meter caused by the tested
equipment :
The knob switch must be turned to the correct position of
measurement range when conducting a measurement. The
test lead and the tested circuit must be disconnected before
turning the knob switch. It is strictly prohibited to switch
the range during a measurement, to prevent damage to the
meter.
When the screen shows " " signal, do not use the
meter.
Do not store or use the meter in a high temperature, high
humidity, combustible, explosive, or strong
electromagnetic environment, or a place with excessive dew
or direct exposure to sunlight.
Do not use abrasives or solvents to clean the meter; please
use a damp cloth or neutral detergent.
When the meter is dampened, please dry it up before
storing it.

To switch on the meter, please turn the knob switch to any
of the function positions.
When the power is turned on, the meter starts an internal
self-diagnosis with a full screen display before corresponding
operations can be conducted.
To ensure correct live operation of the meter, the meter
must be powered off for 5 seconds before restarting it.
Automatic Power Off
The factory setting of the meter: If the user does not
perform any operation on the meter within 15 minutes, it will
automatically turn off the power.
Once the meter automatically powers off, to restart it,
please turn the knob switch to OFF position and then turn it on.
Users can set on their own whether to use the automatic
power off function (Refer to Chapter IV "Setting Function").
Note: The meter will still consume about 1 mA current after
it automatically turns off power, so it is recommended to turn the
knob switch to the OFF position when not using it.
Turn on Back Light
Press the button to turn on the back light, and press the
button again to turn it off.
Automatic Back Light off
The factory setting of the meter: If the user does not turn off
the meter's back light within 30 seconds, the meter will
automatically turn off the back light.
Users can set on their own whether to use the automatic
back light off function (Refer to Chapter IV "Setting Function").
Turn on Flash Light
Press the button continuously for more than 2 seconds
to turn on the flash light, and press the button continuously
for more than 2 seconds again to turn it off.
Automatic Flash Light off
The factory setting of the meter: If the user does not turn off
the meter's back light within 30 seconds, the meter will
automatically turn off the flash light.
Users can set on their own whether to use the automatic
flash light off function (Refer to Chapter IV "Setting Function").

2. Insert the black probe into "COM" plughole and the red probe
into "INPUT" plughole;
3. Connect the probes to the circuit to be measured and read the
measured value after stabilization.

Figure 4
This function can be used to measure the flowing current
when 24V constant DC is applied.
The 24V circuit measurement function can be used to
measure the transmitter circuit.
(The meter can be connected to the transmitter instead of the
signal regulator. )
Warning
The typical value of circuit power supply is 24VDC. The
voltage between terminals may exceed 24V, as the case may be,
such as circuit current value, and the existence of internal series
resistance, and others.
1. Turn the knob switch to the " " position;
2 Insert the black probe into "INPUT" plughole and red probe
into "OUTPUT" plughole;
3. Connect the probes to the circuit to be measured and read the
measured value after stabilization.
Test of Switching Value
1. Turn the knob switch to " " position;
2. Insert the black probe into "COM" plughole and red probe
into "INPUT" plughole;
3. Connect the probes to the contacts on the switch to be tested.
And display "OFF" (open) or "ON" (close) according to the
status of the switch. When the test result is "ON", the buzzer
will tweet. When the switch resistance exceeds 20kΩ, it is
considered to be in an "OFF" status.
Measurement of Thermocouple
1. Turn the knob switch to white " ”" position and select
the corresponding scale division of thermocouple (TC).
2. Insert the thermocouple into "COM" and "INPUT" plugholes.
Ensure that the thermocouple plug with + symbol is
inserted into "INPUT" plughole of the meter.
3. Read the measurement result from the display.
The main display area shows the temperature value and the
auxiliary display area shows the cold junction temperature value.
Users can select automatic compensation (screen display ,
automatic compensation once every 10 seconds) or manual
