II. Operating Instruction
1. mA Output
1a. General Operation 4 - 20mA
1 Turn the power on, and wait until the STBY symbol disappears (about 1 min.)
2 Plug the test leads into the output connectors of calibrator accordingly
(Black to black, red to red). Attach alligator clip if necessary.
3 Move the sliding switch to mA position
4 Press the keypad (including the decimal point) to enter the value of mA
directly.
5 Using the test leads or alligator clips, touch or clip on the terminals to be calibrated.
Note: Always waits until STBY (standby) symbol in the LCD disappears before
any operation.
Note: Maximum 5 digits can be entered. If users enter less than 5 digits (1 to 4 digits), users
must press ENTER button to indicate the end of entry. If users enter 5 or more digits,
calibrator will automatically end the entry and output specified value current.

10
1b. Select 0 - 20mA or 0 - 24mA
The default setting for mA function is 4 - 20mA. But users can select 0 - 20mA or 0-24 mA by
pressing the SHIFT button to enter the SHIFT mode. Then press the NUMBER 2 or
NUMBER 3 button to select desired DC current range. After desired range is selected, press
the shift button to exit the SHIFT mode. Corresponding current range symbol will be
displayed in the LCD.

11
1c. Enter a value less than 1
In the mA functions, the standard way to enter a value less than 1 is to press leading
0 before pressing the decimal point. Though the decimal point can be entered, the
decimal point will not be shown in the LCD.

2. mV,V Output
2a. General Operation 0 - 100mV
1. Turn the power on, and wait until the STBY symbol disappears (about 2
min.).
2. Plug the test leads into the output connectors of calibrator accordingly
(Black to black, red to red). Attach alligator clip if necessary.
3. Move the sliding switch to mV, V position
4. Press the keypad (including the decimal point) to enter the value of mA
directly.
5. Using the test leads or alligator clips, touch or clip on the terminals to be calibrated.
Note: Always wait until STBY (standby) symbol in the LCD to disappear before
any operation.
Note: Maximum 5 digits can be entered. If users enter less than 5 digits (1 to 4 digits), users
must press ENTER button to indicate the end of entry. If users enter 5 or more digits,
calibrator will automatically end the entry and output specified value current.

2b. Select 0 - 1V or 0 - 12V
The default setting for mV, V function is 0 - 100.00mV. Users can select 0 -

14
2c. Enter a value less than 1
In the mV/V functions, the standard way to enter a value less than 1 is to press the leading 0
before pressing the decimal point. Though the decimal point can be entered first, the decimal
point will not be shown in the LCD.
3. Hz, Frequency Output
1. Turn the power on, then plug the test leads into the output connectors of calibrator
accordingly (Black to black, red to red). Attach alligator clip if necessary.
2. Move the sliding switch to Hz position
3. Press the keypad (excluding the decimal point) to enter the value of Hz directly.
4. Using the test leads or alligator clips, touch or clip on the terminals to be calibrated.
5.Because not all the frequencies are available between 126 to 62500Hz, calibrator will
automatically adjust and display the users input value to a frequency, which is available and
always larger or equal to users input.
Note: The resolution of Hz function is 1 Hz. For the range 1-125Hz, all the frequencies in
between are available. But for the range 126 - 62500Hz, not all the frequencies are available
(total 604 frequencies available). Please refer to section III Electrical Specifications for available
frequencies.

4. Thermocouple Calibration of ºC, ºF.
4a. General Operation
1.Turn the power on, and wait until the STBY symbol disappears (about 1 min.).
2.Plug the corresponding connector (K-type connector for K-type thermocouple, J-
type connector for J-type thermocouple, ...) into TC terminals of calibrator and
thermometer to be calibrated.
3.Move the sliding switch to º C, ºF position
4.Press the keypad (including the minus - button) to enter the value of Temperature
directly.

16
Note: Users can plug the connector into the TC terminals of calibrator even
before the power is turned on for better thermal equilibrium between the TC
terminal and thermocouple connector.
Note: Only in the ºC and ºF functions, the negative values are allowed to be entered. To enter
negative temperature, press the minus"-" button first.
Note: Maximum 4 digits (including the "-" sign) can be entered.
If users enter less than 4 digits (1 to 3 digits), users must press ENTER button to indicate the
end of entry. If users enter 4 or more digits, calibrator will automatically end the entry and
output specified value of temperature.

4b. Select ºC, or ºF
Users can select ºC or ºF by pressing the shift button to enter SHIFT mode. Then press
the NUMBER 5 button repeatedly to select desired temperature unit. After desired unit is
selected, press the SHIFT button again to exit the SHIFT mode. Corresponding voltage
ºC or ºF symbol will be displayed in the LCD.

18
4c. Select K, J, E, or T type Thermocouple
Users can select K, J, E, or T type Thermocouple by pressing the shift button to enter
SHIFT mode. Then press the number 6 button repeatedly to select desired type of
thermocouple. After desired type is selected, press the shift button again to exit the SHIFT
mode. Corresponding thermocouple type (K, J, E, or T) symbol will be displayed in the LCD.

19
4d. Enter a Negative Temperatura
The resolution of temperature is 1 degree, so the decimal point is used a minus "-" sign.
To enter a negative temperature, press the "-" button first.
5. % input in the mA, mV, V functions
In the mA, mV, or V function, users can enter percentage. To enter percentage (%)
1. Users press the shift button first, then SHIFT symbol will be displayed in the LCD.
2 Press % button first, then press the number (no decimal number, the %
resolution is 1%).
3 After percentage is entered, the percentage will be displayed in the upper
LCD, and the corresponding value will be displayed in the lower LCD.
4. The corresponding value is calculated based upon the range selected.
4-20mA: 1% = 0.16mA
0-20mA: 1% = 0.2mA
0-24mA: 1% = 0.24mA
0-100mV: 1% = 1mV
0-1V: 1% = 0.01V
0-12V: 1% = 0.12V
5. To exit the percentage-input mode, press the SHIFT button again.
6. After the SHIFT button is pressed, the upper LCD will become blank, while the lower
LCD retains its last value.
