Difference Computation of the Input Between Two Channels
You can assign a channel from other linked 30-CH Fast Digital Thermometer WE7231s
or equivalent modules as the reference channel, and calculate the difference against the
input of the reference channel, select the Delta check box of the channel on which to
calculate the difference.
The Moving Average of the Measured Values
Select the On check box under Average to calculate the moving average of the
measured value. Select the average from 2 to 100.
Fast Scan Mode
If you select the Fast Scan Mode check box, only the odd-numbered channels from
groups 1 (CH1 to CH15) and 2 (CH16 to CH30) are available, thereby allowing a short
sampling interval.
When Fast Scan Mode is OFF (normal scan mode), all channels are enabled.
Sampling Interval
The sampling interval applies to all channels.

Note
• If any channel uses the 200 k

Ω
range, an additional 0.8 s for normal scan or 0.4 s for
fast scan are added.
• If you change the sampling interval after starting measurement, the Time Since the Start of
Measurement display will not be accurate.
Reference Junction Compensation
To carry out reference junction compensation using the internal circuitry, select Internal
from the RJC Source list box. Select External for external reference junction
compensation. Set the reference junction temperature when performing external
reference junction compensation. This setting applies to all channels.
