Measurement Range：K -200 to 1370°C / E -200 to 800°C
HOLDThe thermometer stops measurement
by the HOLD key and holds the present readings.
Auto power-offThe thermometer will turn the power off automatically after 5minutes.
Resolution changePress the［RESO］ key to change the resolution of readings.
P/V HoldThe peak (Max.) value and the valley (Min.) value can be displayed by the P/V HOLD key on the sub-display.
BacklightThe backlight will operate by the Backlight key and the LCD display will be visible even in a dark place.
CalibrationThe displayed value can be adjusted the CAL SET key.
Alarm outputThe thermometer gives an alarm when readings go beyond the high or low limits.
