3. Setting of Each Function

●Name of each part

●Display

Lit-up display

Blinking display

Turned-off display

●Function of each switch

Functions switch F : Change between the measuring

mode and the setting mode.

Mode switch M : Change parameter item at the setting

mode.

Shift switch ＞: Move to the next action or shift the

value.

Up switch ∧: Scroll or increase the value or figure

●Setting mode

- Changes to the settings are saved to EEPROM when returning to the measuring mode. Display temporally turns off the light

- Once flashing the new setting value in the setting mode, it is saved into the memory, and peak value (or bottom value) goes clear.

- If you do not touch any switch for 5 minutes at the setting mode, it automatically returns to the measuring mode without saving

changes.

3.1 Setting method

3.1.1 Average operation

Average operates the interval average or the moving average.

Example) Changes the non-average operation to the moving average of 8-data.

- Since the interval average operates 6-data, display cycle is approx. 1.2s.

- In case of moving average, display cycle is approx. 200ms.

●Input terminals

[ Thermocouple input ]

Pay attention to the polarity when wiring.

CJS is not compatible.

Make sure that the serial number

of the CJS and the meter must match.

[ RTD input ]

Connect 3-wire of the RTD.

●Hold (HOLD)

Display can be held by connecting the Hold terminal and the Common terminal.

Active “L” IIL≦-1mA, “L”=0 to 0.8V, “H”=3.5 to 5V

●Peak Hold (PH)

Maximum value is displayed by connecting the Peak Hold terminal and the Common terminal. “PH” and LED are lit during the

peak hold function. This function is released by disconnecting the PH terminal.

Active “L” IIL≦-1mA, “L”=0 to 0.8V, “H”=3.5 to 5V

●Bottom Hold (PH)

If your meter code is –A01, PH terminal is for the bottom hold. Minimum value is displayed by connecting the Peak Hold terminal

and the Common terminal. “BH” and LED are lit during the bottom hold function. This function is released by disconnecting the

PH terminal.

Active “L” IIL≦-1mA, “L”=0 to 0.8V, “H”=3.5 to 5V

●Common (COM)

“COM” terminal is used for Hold and Peak (or Bottom) Hold terminals.

NOTE: Those terminals, COM, HOLD and PH, are not isolated to the input.

Use a photo-coupler or switch to insulate.

It is essential when using the input floating.

●Power Supply (P1(-), P2(+))

The power supply voltage is specified on the terminal plate at delivery from our factory.

- AC power supply(3): Use the meter within the range AC85 to 132V.

- AC power supply(5): Use the meter within the range AC170 to 250V.

- DC power supply(9): Use the meter within the range DC20 to 30V.

Connect +24V positive of DC power to P2 (+), and 0V negative side to P1 (-).

CAUTION

●Do not use the product with the voltage out of the rated range as it may cause breakage of the products.

5. Maintenance

Store the meter within the rated storage temperature (from -20 to +70oC). When the front panel or the case is cleaned, use soft cloth

dipped with cleaner liquid. Do not use organic solvent like benzene or paint thinner as they may deform or discolor the case.

6. Calibration

In order to maintain long term accuracy, periodical calibration at an interval of about one year is recommended. Make a calibration in

the ambient condition of 23oC±5oC, 75%RH or less.
