Operating Instructions

Power ON/OFF

Press the POWER button to turn the instrument on. Press and hold the
POWER button to turn the instrument off. When the instrument is on, it
will begin an internal self-diagnosis at which time the full screen will be
displayed. When complete, the instrument is ready to take measurements.

Auto Power-Off

As a default the instrument will automatically turn off after 15 minutes of
inactivity. To turn off this feature:

1. Turn the meter off.

2. Press the POWER button (to display the full screen).

3. Quickly press the RANG button when the instrument is in the
maintenance state as indicated by "1.8.8.888".

4. "AP-XX" will now appear on the display.

5. Press the button to toggle between "AP-ON" & "AP-OF". "AP-OF"
indicates that the no automatic power-off function is disabled, while
"AP-ON" indicates the automatic power-off function is enabled.

6. Press the ZERO button to save the required setting.

7. Press and hold the POWER button to exit the maintenance state and
turn the instrument off.

Output Function

• The output terminal of the instrument can produce DC voltages set by

the user or can simulate resistance.

Do not apply any voltage to the output terminal during the operation.

If any improper voltage is applied to the output terminal, it will cause

damage to the internal circuit.

Simulating Output from DC Voltage

1. Insert one end of the test lead into
the output (TC/mV) jack of the
meter and connect the other end
to the input of the instrument under
test, as shown in the diagram to
the right.

2. Press the FUNC button to select
"DC Voltage Output". "V" will
appear on the display.

www.GlobalTestSupply.com

continued...

3. Press the RANG button to select the range of 1.0000V or 100.00mV.
"V" or "mV" will appear on the display.

4. Press the and buttons to move the on-screen cursor in order to
select the desired digit on the display.

5. Press the and buttons to change the numerical value of each
digit. (Numerical value cannot be changed beyond range maximum.)

6. Press the ZERO button and the output will be set to 00.00mV
or 0.0000V.

Simulating Output from Thermocouple (TC)

1. Insert one end of the test lead into the output (TC/mV) jack of the
meter and connect the other end to the input of the instrument under
test, as shown in the above diagram.

2.

Press the FUNC button to select "Thermocouple Output". "R" and
"°C" will appear on the display.

3. Press the RANG button to select the type of thermocouple.

4. Press the and buttons to move the on-screen cursor in order to
select the desired digit on the display.

5. Press the and buttons to change the numerical value of each
digit. (Numerical value cannot be changed beyond range maximum.)

6. Automatic compensation for reference-junction temperature.

7. Press the ZERO button and the output will be directly set to 0000°C
(R or S type), 400°C (B type) or 0000.0°C (other type).

8. Press the °C/°F button to select the unit °C or °F.

Note: During the direct calibration of an instrument with reference-junction
temperature compensation, it is recommended to press the RJ-ON button
so that the instrument can start the function of automatic reference­junction compensation. Thus providing the required thermo-electromotive
force for output followed by displaying the symbol "RJ-ON" where:

Output thermoelectric force = corresponding emf of set
temperature – emf of room temperature

•

It takes two seconds for the instrument to start its internal referencejunction
temperature. After this, each automatic compensation occurs at
10 second intervals.

• If there is a change in the operating ambient temperature, do not start

the operation until the built-in compensating sensor has become stable
(approx. 10 minutes).

• If there is no need for the simulator to perform the function of automatic

reference-junction compensation, press the RJ-ON button and the
symbol "RJ-ON" will no longer appear in the display.

Simulating output from thermal resistance or RTD

1. Insert one end of the test lead
into the output (RTD/Ω) jack
of the meter and connect
the other end to the input of
the instrument under test as
shown in the diagram to the
right. The dedicated test leads
supplied with the simulator are
intended for a 2-wire system
for testing output according to

RTD

2w

user's requirement.

Note: An additional set of test leads are required for 3-wire or
4-wire systems.

2. The display of the symbol "OUTPUT" denotes the instrument is in an
output state.

3. Press the FUNC button to select thermal resistance output or RTD
output as indicated by "Ω" or "°C" and "Cu10" (Copper 10 ohm RTD)
on the LCD display.

4. While RTD function is selected, press the RANG button to select the
type of RTD.

5. Press the

and buttons to move the on-screen cursor in order to

select the desired digit on the display.

6. Press the and buttons to change the numerical value of each
digit. (Numerical value cannot be changed beyond range maximum.)

7. Press the ZERO button and the output will be directly set to 000.0°C.

8. Press the °C/°F button to select the unit °C or °F.

Note: The instrument produces a simulation resistance up to 400Ω at
its output terminal (RTD /Ω). The method of simulating resistance output
is to send out an appropriate voltage 'Vx' according to the excitation
current 'Ix' produced by the calibrated instrument. Because R (set
resistance) = Vx (output voltage) / Ix (excitation current), the calibrated
device must provide an excitation current tothe simulator. The excitation
current should range from 0.5mA to 2mA.

Note:

When testing the resistance output of a 4-wire system while
employing a 2-wire connection, you should take into consideration the
error (approx. 0.1Ω) arising from the lead resistance of the test leads. If
the capacitance between the resistance output terminal of the simulator
and the tested instrument is more than 0.1μf, the simulator will produce
improper resistance.

Battery Replacement

When the battery symbol, , appears on the display, the battery needs to
be replaced. In order to replace the battery, proceed with the following steps.

1. Ensure that the meter is turned OFF
and remove any test leads from the
meter's terminals.

2. Lift the tilt stand on the back of the unit
to access the battery compartment
door which can be removed using a
Phillips head screwdriver.

3. Replace the 2 x AA batteries in the lid
of the battery compartment.

4. Reinstall the compartment lid by ensuring that battery terminals
touch the unit's contact points and snap into place.

5. Tighten the screw to secure the battery compartment cover.

Note: Ensure battery door is closed and secured in place before using
the meter. To ensure proper operation, please wait 5 seconds before
turning meter on after changing batteries.
