Notes
1. Only for U1282A
2. The specification above is specified after 60 minutes of warm-up time.
3. The accuracy does not include the tolerance of the thermocouple probe.
4. Do not allow the temperature sensor to contact a surface that is energized about 30 Vrms or 60 V DC.
Such voltages pose a shock hazard.
5. The temperature calculation is specified according to the safety standards of EN/IEC-60548-1 and
NIST 175.

Notes
1. Overload protection: 1000 Vrms for short circuits with < 0.3 A current.
2. The accuracy for all ranges is specified based on a film capacitor or better, and after the Null
function is used to subtract the test lead resistance and thermal effect (by opening the test leads).
3. The maximum display is 1200 counts / 12000 counts selectable
