The meter is powered by two LR6 alkaline batteries (AA).
To avoid electrical shock or personal injury:
Remove test leads from the meter before opening the battery door.
Close and latch the battery door before using the Meter.
The new and old batteries can not be mixed.
Make sure the battery's odes are in accordance with the marks illustrated in
battery pool when replacing them.
Take out the batteries if the meter won't be used for a long time.
Dispose the old batteries in accordance with the local law.
1. Turn the rotary switch to OFF and remove the test leads from the terminals;
2. Take off the support of the meter, remove the battery door by a standard-
blade screwdriver, and then take off the battery case;
3. Replace with two new batteries;
4. Reinstall the battery case, spin the screws and tighten screws.

Section Three Maintenance
This section provides some basic maintenance procedures. Repair, Calibration, and
servicing not covered in this manual must Be performed by qualified personnel. For
maintenance procedures not described in this manual, contact a Service Center.
（1）General maintenance
Periodically wipe the case with a damp cloth and detergent; do not use
abrasives or solvents.
Take out the batteries if the meter won't be used for a long time.
Dirt or moisture in the terminals can affect readings.
Clean the terminals as follows:
1Turn the meter off and remove all test leads.
2Shake out any dirt that may be in terminals.

Press〔power〕key to electrify the meter, and repress〔power〕key for more
than 1 second to cut off the power.
When turning on the power, the meter starts to make inner diagnose and display in
full screen, and then undertakes corresponding operation.
Section Four Power on/Power off the Meter
（1）Turn on/off the meter
Note
To ensure correct electrifying operation, please wait for 5 seconds to turn on the
meter after cutting off the power.
（2）Automatically turn off the power
The default factory value is set as: the meter will automatically turn off if no
operation has been made within 15 minutes. The Users can set by themselves
to choose whether using this function or not (See detailed section).
Section Five Output of the Meter
The Instrument may output resistance or thermal resistance analog signal set by
the User through corresponding terminal (OUTPUT).
Caution
Do not apply any voltage to output terminal; otherwise damage to interior circuit
may occur if the voltage is not proper.
（1）Resistance or thermal resistance(RTD)simulate output
Note
·Resistance simulate： The meter generates a simulate Resistance value
Ranging from 400 to 4000 from the output terminal (RTD/Ω). The output method for
simulate resistance is that the meter output scorresponding voltage “Vx “ according to
incentive current “Ix” generated by the calibrated meter, and for the R(set resistance)
equals to Vx (output voltage)/lx(incentive current), thus the calibrated body should
supply a simulate

Current to this meter. For realizing the correct simulateoutput of 400Ω,the incentive
current should be within ±0.5～±3mA range;for simulate output of 4000Ω,the
incentive current should be within ±0.05～±0.3mA range;
Note
ꞏResistance simulate：
When the output resistance is 4-wired for Calibration, the error generated
by there sistance（approximately 0.1）of test lead should be considered if the
User semploy two wires connection method; The meter may generate incorrect
resistance valueif the capacity between the output terminals and the measured
meter is higher than 0.1 uf.

Section Six Measurement
Warning
Usage: the maximum voltage allowed between the terminals and within the
terminals and the ground is 30V, any exceeding over this voltage may cause
damage to the meter and even make injury to persons.
Caution
Usage: do not apply any voltage exceeding the maximum allowed to the input
terminals, which may cause damage to the meter.
Usage: when connected to the measured meter, please first cut off the electricity
supply. A connection to the measured meter with power may cause damage of
this meter.
Usage: pay particular attention to not to connect the current signal to the input
terminal, incorrect connection may cause damage to this meter and the meter
under measured.

1. When pressing〔OUTPUT/INPUT〕key, symbol 'INPUT' may display on the
screen, indicating that the instrument is on input state.
2. Press〔FUN〕key to select the needed measurement function, corresponding
units and Graduation for thermal resistance will display on the screen.
3. Press〔4/3/2W〕key to select 2-wire, 3-wire or 4-wire measurement methods.
