 Change Settings
Example: When the temperature is measured by two instruments
When the measured values (PV) are as shown in the following:
Main unit = 198 °C
Recorder = 200 °C
If a PV bias correction value of +2 °C is added to the measured value the
main unit, the displayed value become:
Displayed value = Measured value (PV) + PV bias
= 198 °C + 2 °C = 200 °C
The setting procedures is described in the following.
1. Press the SET key at “Pb” is displayed.
2. Press the UP key to change the number to 2.
3. Press the SET key to store the new set value.
The display goes to the next parameter.
7.8 ON/OFF Action Differential Gap (oH)
Setting range: Temperature input: 0 to 100 °C [°F] or
0.0 to 100.0 °C [°F]
Voltage/current inputs: −199.9 to +200.0 %
Factory set value: Temperature input: 2 °C [°F] or 2.0 °C [°F]
Voltage/current inputs: 0.2 % of span
 Change Settings
Example: Change the On/Off Action differential gap from “2 °C” to “4 °C”
1. Press the SET key at “oH” is displayed.
2. Press the UP key to change the number to 4.
3. Press the SET key to store the new set value. The display goes to the
next parameter.
7.9 Alarm 1 Differential Gap (AH1)
Alarm 2 Differential Gap (AH2)
Setting range: Temperature input: 0 to 100 °C [°F] or
0.0 to 100.0 °C [°F]
Voltage/current inputs: 0.0 to 10.0 %
Factory set value: Temperature input: 2 °C [°F] or 2.0 °C [°F]
Voltage/current inputs: 0.2 % of span
 Change Settings
Example: Change the Alarm 1 differential gap from “2 °C” to “4 °C”
1. Press the SET key at “AH1” is displayed.
2. Press the UP key to change the number to 4.
3. Press the SET key to store the new set value. The display goes to the
next parameter.
7.10 Setting Limiter [High] (SLH)
Setting Limiter [Low] (SLL)
For voltage or current input, set scaling within the input range.
See 9. INPUT RANGE TABLE.
Factory set value varies depending on the instrument specification.

RTD Pt100 −199.9 to +649.0 °C −199.9 to 999.9 °F
JPt100 −199.9 to +649.0 °C
* Limit setting becomes SLH ≥ SLL.
When changing the high-limit (SLH) and the low-limit (SLL) limiter
settings, always set the set-value (SV) within the limiter range.
 Change Settings
Example: The input range (input scale range) is from 0.0 to 100.0 °C,
the setting limiter (high) is 80.0 °C.
1. Press the SET key at “SLH” is displayed.
2. Press the shift key to high-light the tens digit.
3. Press the DOWN key to change the number to 8.
4. Press the SET key to store the new set value.
The display goes to the next parameter.
8. ERROR DISPLAYS
 Error display
RAM failure (Incorrect
set data write, etc.)
Turn off the power once. If an
error occurs after the power is
turned on again, please contact
RKC sales office or the agent.
 Overscale and Underscale
Measured value (PV)
[Flashing]
PV is outside of input
range.
[Flashing]
Overscale:
PV is above the high
input display range limit.
[Flashing]
Underscale:
PV is below the low
input display range limit.
Check input type, input range,
sensor and sensor connection.
