This program reads the digital values of temperature conversions made on CH.1
to CH.4 of the Q64RD.
Sampling process is performed on CH.1 and CH.4, average process on CH.2 per
500 times, and average process on CH.3 per 1000ms. If a write error occurs, the
corresponding error code appears in BCD.
(a) Initial settings
• Temperature conversion enabled channel .......................... CH.1 to CH.4
• Sampling channel.................................................................CH.1, CH.4
• Count-specified average process channel .......................... CH.2
• Time-specified average process channel ............................ CH.3
(b) Devices used by user
