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 connector 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 4digits), users must press ENTER button to indi-

cate the end of entry. If users enter 5 or more digits, calibrator

will automatically end the entry and output specified value cur-

rent.

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 mcde. 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 symboI

wili be displayed in the LCD.

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 mV directly.

5. Using the test leads or alligator clips, touch or clip on

the teminals to be calibrated.

Note : Always wait until STBY (standby) synbol in the 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 of more digits, calibrator will

automatically end the entry and output specified value voltage.

333 : 28-09-2012

2b. Select 0 -1V or 0-12V

The default setting for mV, V function is 0 - 100.00mV. Users

can select 0 - 1.0000V or 0 -12.000V by pressing the SHIFT

button to enter SHIFT mode. Then press the NUMBER 4

button repeatedly to select desired DC voltage range. After

desired range is selected, press the SHIFT button again to

exit the SHIFT mode. Corresponding voltage range symbol

will be displayed in the LCD.

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 atways larger or equal to users input.

Note : The resolution of Hz funcfion 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 0C, 0F

4a. General Operation

1. Turn the power on, and wait until the STBY symbol

disappears (about1 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 0C, 0F position

4. Press the keypad (including the minus - button) to

enter the value of Temperature directly.

333 : 28-09-2012

4b. Select 0C or 0F

User can select 0C or 0F 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 temperature 0C or 0F symbol will be displayed in

the LCD.

17

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 0C and 0F 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.

4c. Select K, J, E, or T type Themocouple

Users can select K, J, E or T type Themocouple by pressing the

shift button to enter SHIFT mode. Then press the number 6 button

repeatedly to select desired type of themocouple. After desired

type is selected, press the shift button again to exit the SHIFT

mode. Corresponding thhemocouple type (K, J, E or T) symbol

will be displayd in the LCD.

333 : 28-09-2012

4d. Enter a Negative Temperature

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.

21

5. % Output in the mA, mV, V function

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-output mode, press the SHIFT

button again.

6. After the SHIFT button is pressed, the upper LCD will

become blank, while the lower LCD remains its last value.

6. Easy Step in the mA, mV, and V Functions

While the percentage is entered and calibrator is still in the SHIFT

mode, users can step up or down by the percentage entered.

The maximum percentage is 100% while the minimum percentage

is 0%. If the next step up or down exceeds the maximum or

minimum percentage, the percentage will stay in the previous step.

Example 1 : Step Up and Down (25%) :

25% -> 50% -> 75% -> 100% -> 75% -> 50% -> 25% -> 0% ->

25%

Example 2 : Step Up and Down (30%) :

30% -> 60% -> 90% -> 60% -> 30% -> 0% -> 30%

7. Auto Ramp in the mA, mV, and V functions

In the mA, mV, and V function, auto ramp function is available to

the users. To start the ramp function :

1. Press the SHIFT button to enter the SHIFT mode.

2. Press the NUMBER 7 key to starl

3. Ramp function increment from 0% to 100%, then

decrements from 100% to 0% repeatedly. The resolution

of each step is 1% (with respect the range selected) at

an interval of 0.08 seconds. So it takes 8 seconds to

ramp from 0 to 100%.

4. To temporarily stop the ramp function, press the

NUMBER 7 key, and the output will stay at the value

when the NUMBER 7 key is pressed. These features

will facilitate the checking of trigger point of tested device,

such as valve controller.

5. To restart again, press the NUMBER 7 button again.

6. To return to the regular output mode, press the SHIFT

button again when ramp function is stopped.

Note : Do not press any button while the calibrator is performing

the ramp function (except NUMBER 7 button to stop the ramp

function).

8. How to Get Negative Output

If negative output (mA, mV, or V) is needed, users can achieve

it by interchange the connectian of test leads.
