• In the test mode stop state, press the MENU button,
SKIP-DOWN button (three times), and PLAY button
(twice) in this order.
• "TM$$%%" appears. ($$ = temperature code, %% =
3
temperature reference value)
"TPin##" will appear when pressing the SKIP-UP button
4
once. (## = TEMP input AD value)
Calculate the temperature correction value by referring
to the ambient temperature and the "Temperature
5
measurement value correction table".
Calculate the temperature reference value according to
the formula below.
• Temperature reference value = Microcomputer TEMP input
6
AD value + Temperature correction value
Press the SKIP-DOWN button once to display "TM$$%%".
