7.1.5 Difference Computation Setting (DELT Setting)
To obtain the difference between the measured values of two channels, proceed as
follows. Note that this setting can only be applied if the reference channel is of the
VOLT, TC or RTD type.
MENU:
SETTING PROCEDURE:
Press the MENU-key for three seconds to enter the SET mode.
Select the ‘SET=RANGE’ display by using the UP/DOWN-keys.
Then press the ENT-key.
Use the UP/DOWN-keys to select the desired channel.
Note that channel No.1 cannot be of the ‘DELT’ type.
Then press the ENT-key.
Use the UP/DOWN-keys to select ‘DELT’.
Then press the ENT-key.
Enter the reference channel number using the UP/DOWN-keys.
Note that the reference channel number must be lower than that of
the channel being set. Therefore channel No.1 cannot be of the
‘DELT’ type.
Then press the ENT-key.
The display which appears will show the same minimum value of
the recording span as of the reference channel.
Use the UP/DOWN and RIGHT-keys to set the minimum value.
Press the ENT-key.
Note that in case of VOLT, the input range of the DELT-channel
must be within the range of the reference channel. The difference
in measured value from the reference channel will be recorded on
the DELT-channel.
The display which appears will show the same maximum value of
the recording span as of the reference channel.
Use the UP/DOWN and RIGHT-keys to set the maximum value.
Note that LEFT cannot be equal to RIGHT.
Press the ENT-key.
Note that in case of TC, RTD, the maximum span values can be
found by taking the ±value of the input range width. E.g. input
range of TC type L = –200 to 900°C: maximum span values will
be at ±1100°C.
The setting is completed.
Press the ENT-key to return to the ‘02:MODE=DELT’ display, or
press the ESC-key to go to the ‘SET=RANGE’ display; or press
the MENU-key for three seconds to return to the Operation mode.
