Temperature Sensor: K Type thermocouple
Note:
1. Accuracy does not include error of the thermocouple probe.
2. Accuracy specification assumes ambient temperature is stable to ± 1°C.
For ambient temperature changes of ± 5°C, rated accuracy applies after 1
hour.
3. The meter's operating temperature must be between 18°C and 28°C;
otherwise measurement accuracy is not guaranteed.
[1] The display will show " OL " if the temperature being measured is higher
than 1010°C ( 1850°F ) or lower than - 30°C ( - 22°F ).

Description
The built-in buzzer will sound if the resistance is less than
about 50Ω.
The buzzer will not sound if the resistance is more than
100Ω.
The buzzer may or may not sound if the resistance is
between 50Ω and 100Ω.
Description
The approximate forward voltage
