(1) Difference(Deviation)
It is available to set when Input Type(input specification) is temperature sensor
(thermocouple, RTD). It displays the deviation of Reference Channel (Reference channel)
measuring value.
(Display value = standard channel measuring value – reference channel measuring value)
 The set channel as analog (current, voltage) of Input Type (Input specification) is not
able to set as Reference Channel (reference channel).

If there is no set reference channel, it displays standard channel measuring value.
 If any one of reference channel, or standard channel is break (BURN), upper limit
value (HHHH), lower limit value(LLLL) status, it displays as correspond value. If you
select the channel which is used Difference function as reference channel, it displays
the value based on calculating actual measuring value, not display value of reference
channel.
(2) Linear
It applies lower limit scale and upper limit scale to lower limit input value and upper limit
input value and displays this values.
In case lower limit input value: -5V, Upper limit input value: +5V and
in case lower limit scale: -1000, upper limit scale: 1000
if current input value is 2V, display value is 400.
Display value =
Input value − Lower limit input value
Upper limit input value − Lower limit input value
× (Upper limit scale − Lower limit scale) +
Lower limit scale

(3) Root
In case voltage, current input type, this mode is used when input value is calculated by Root
(
√ ) for the desired display value. Differential pressure signal of differential pressure flow
meter is calculated Root(
√
) for the to-be measured flux. This function is used to measure
flux by input value.
In case lower limit input value: -5V, upper limit input value: +5V and
in case lower limit scale: -1000, upper limit scale: 1000,
if current input value is 2V, display value is approx. 673.32.
Display value =
