62 to 86 [17 to 30˚C]
−38 to 190 [−39 to 88˚C]
(When the temperature is 0˚F [0˚C] or less, "–" and
temperature are displayed by turns.)
−38 to 190 (−39 to 88˚C)
(When the temperature is 0˚F [0˚C] or less, "–" and
temperature are displayed by turns.)
−40 to 327 [−40 to 164˚C]
(When the temperature is 0˚F [0˚C] or less, "–" and
temperature are displayed by turns.)
(When the thermistor detects 100˚F or more,
hundreds digit, tens digit and ones digit are
displayed by turns.)
0 to 458 [0 to 255˚C]
(When the temperature is 100˚F or more, hun-
dreds digit, tens digit and ones digit are displayed
by turns.)

(Overvoltage/Undervoltage/Overcurrent)
• Display examples for multiple errors:
Overvoltage (01) + Undervoltage (02) = 03
Undervoltage (02) + Power-sync signal error (08) = 0A
