Setting Measurement Conditions
Selecting the Measurement Function
Choose from TC (thermocouple), DCV (DC voltage), RTD (resistance temperature
detector), and OHM (resistance). RTD (resistance temperature detector) and OHM
(resistance) can only be selected for the odd-numbered channels between CH1 and
CH15, or the even-numbered channels between CH16 and CH30. Also, if at least one
channel among CH1-CH15 or CH16-CH30 is set to RTD (resistance temperature
detector) or OHM (resistance), measurement on the even-numbered channels from CH1
to CH15 or the odd-numbered channels from CH16 to CH30 will no longer be possible.
Hence, you will not be able to enter measurement function settings on those channels.
Selecting the Type of Thermocouple and Resistance Temperature Detector and the Range
The following is a breakdown by measurement function of the type, range, and
measurement range that can be selected.

NULL
For each channel, you can set whether the null value is applied to measurement values.
When the NULL check box is selected, the measured value is equal to the actual value
minus the null value. Using the NULL value, the residual voltage can be cancelled, for
example when measuring in microvolts.
If the NULL check box is selected during measurement, the value measured immediately
thereafter is used as the null value. If the NULL check box is selected while
measurement is stopped, the value measured immediately after measurement starts is
used as the null value.
If you click the NULL Meas button, the null values of the channels whose NULL check
boxes are selected are measured again.
