7.2.3 Channel Offset
For channel offset setting, set the value to be added to an actual process variable.
The input value can be set from -19999 to 99999.
Example: Adding the value (3.0) to Channel 2
Enter engineering mode (See the Key Operation to Enter
Engineering Mode on page 76). Use the
key to
display "
", and press the “ENT” key.
Use the
key to select "
", and press the “ENT”
key.
Use the
key to alter a sign/numerical value or shift a
decimal point. Use the
key to shift a digit. Once the
numerical value is determined, press the “ENT” key.
7.2.4 Reference Junction Compensation
The following describes how to set the method for compensating an electromotive force generated
between a thermocouple wire or compensation lead wire and a terminal. There are three
compensating methods as follows:
• A method of compensation using the built-in temperature sensing element (INT: Internal
compensation).
• A method of compensation by keeping an external compensator’s temperature constant (EXT:
External compensation). For external reference junction compensation voltage, -19999 to 19999 V
can be set as an input.
• By connecting the terminal of the external junction box to one input of the recorder, compensates the
input of the other channel. (CH: Channel input compensation)
For this recorder, internal compensation (INT) default value has been set.
Example: Setting the external compensator’s temperature constant voltage for Ch2 to 391 V
(Thermocouple T input, external compensator’s compensating temperature 10
,
Electromotive force input 391 V)
Enter engineering mode (See the Key Operation to Enter
Engineering Mode on page 76). Use the

Use the
key to select "
", and press the “ENT”
key.
Use the
key to select "
", and press the “ENT”
key.
Use the
key to alter a numerical value, and the
key to shift a digit. Once the numerical value is
determined, press the “ENT” key.
Once setting is completed, the recorder will return to
channel setting mode.
