●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.

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.

3.1 Setting method
3.1.1 Display scaling - Offset setting
Offset display can be set to an arbitrary value.
Example: With the rated input 1to 5V, the display at the input 1V is adjusted from 0 to 100.
- Offset display means the
display at 0mV input for the
voltage measuring range, at 1V
input for the 1-5VDC range,
and at 4mA input for 4-20mA
range.
Λswitch:
0→1→2→････→9→0→1
In case of 102-digit:
0→1→2→････→9→-9→-8→
････→-1→-0→0→1
3.1.2 Display scaling - Full scale setting
Full scale display can be set to an arbitrary value.
Example: With the rated input 1 to 5V, the display at the input 5V is adjusted from 999 to 599.
- Full scale display means the
display at maximum value input.
Λswitch:
0→1→2→････→9→0→1
In case of 102-digit:
0→1→2→････→9→-9→-8→
････→-1→-0→0→1
3.1.3 Offset fixing
Display can be fixed to the offset value when the input value is lower than the offset value.
Example: Change the offset fixing function from disable to enable.
- If your meter chooses
the4-20mA range and sets the
display scaling to 100-500,
display shows 100 even though
the input signal is less than
4mA.

3.1.4 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. 400ms.
- In case of moving average, display cycle is approx. 67ms.
3.1.5 Zero set
Reset the input signal electrically to zero.
Example: Change the zero set function from disable to enable.
- If you enable the zero set and
cause short circuit between the
zero set terminal and the COM
terminal, display shows the
offset value (as same as the
setting value at chapter 3.1.1)
Example:
If you execute the zero set at
100 when scaling 0-500,
display would show -100 to
0 to +400.
:Enable the zero set.
:Disable the zero set.

3.2 Adjustment function
3.2.1 Zero adjustment
Fine calibration of the offset displayis available to meet the real input value.
Example: your meter is 1-5V input, and when inputting 1V, displayed value is 5, not 0.
3.2.2 MAX adjustment
Fine calibration of the maximum display is available to meet the real input value.
Supply the input as close as the rated maximum value.
Display shows the input value. (DP1 and DP2 lit up)

CAUTION
● Do not miswiring. Otherwise, the meteris broken.
● To avoid an electrical shock, turn the power off when wiring.
● Do not wire with moistened hands. Locate away from the wet place.
●Do not touch terminals when turning the power on.

●Input terminals (INHi, INLo)
Pay attention to the polarity when wiring. Connect input of higher electric potential to Hi. Input and power line shall lay separately.
Otherwise, display may be unstable.
●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
●Decimal point (DP1, DP2)
Decimal point is programmable.
Connect and short-circuit the desired decimal point terminal,
DP1 or DP2, and the common terminal.
Active “L”, IIL ≦-1ｍA, “L”=0 to 0.8V, “H”=3.5 to 5V
If you duplicate both DP1 and DP2, decimal point does not light up.
●Peak Hold (PH)
Maximum value is displayed by connecting the PH terminal and the Common terminal. “PH” 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 PH terminal and the
Common terminal. “PH” 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
●Zero set (ZS)
Zero set enables by choosing “on” at the rear switch. Zero set value is memorized into EEPROM for approx. 10 years.
Active “L” IIL≦-1mA, “L”=0 to 0.8V, “H”=3.5 to 5V
- Method:
1. Shift the rear switch of the zero set to on side.
2. Input the zero set value, and cause short circuit between the zero set terminal and the COM terminal. Display shows 0 (when you
set the offset value to 0).
3. If you disconnect the zero set terminal and the COM terminal, zero set value is memorized and zero set function starts.
Display value = Input value – Zero set value.
- Release
1. Shift the rear switch of the zero set to off side. But zero set value is still memorized.

●Common (COM)
“COM” terminal is used for Hold and Peak (or Bottom) Hold, Zero set, and Decimal point terminals.
NOTE: Those terminals, COM, DP1, DP2, HOLD, ZS, 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.
Refer to the chapter 3.2 for calibration.
Make a calibration in the ambient condition of 23oC±5oC, 75%RH or less.
