Notes for DC voltage specifications:
1. The accuracy of the 600 mV range is specified after the Null function is used to subtract the thermal effect (by shorting the test leads).
2. For VZ_LOW (low input impedance) measurements, auto-ranging is disabled and the multimeter’s range is set to 600 V in the manual ranging mode.
Notes for resistance specifications:
1. Overload protection: 600 Vrms for short circuits with < 0.3 A current.
2. Maximum open voltage is < +3 V.
3. Built-in buzzer beeps when the resistance measured is less than 23 Ω ± 10 Ω. The multimeter can capture intermittent measurements longer than 1 ms.
4. The accuracy of the 600 Ω to 6 kΩ range is specified after the Null function is used to subtract the test lead resistance and thermal effect (by shorting
the test leads).
5. For the ranges of 6 MΩ and 60 MΩ, the RH is specified for < 60%.
Notes for diode specifications:
1. Overload protection: 600 Vrms for short circuits with < 0.3 A current.
2. Built-in buzzer beeps continuously when the voltage measured is less than 50 mV and beeps once for forward-biased diode or semiconductor
junctions measured between 0.3 V and 0.8 V (0.3 V ≤ reading ≤ 0.8 V).
3. Open voltage for diode: < +3 V DC.
4. The maximum display for diode measurements is 2100 counts.
Notes for DC current specifications:
1. Overload protection for 60 μA to 600 μA range: 600 Vrms for short circuits with < 0.3 A current.
2. Overload protection for 6 A to 10 A range: 11 A/1000 V; 10 × 38 mm fast-acting fuse.
3. Specification for 10 A range: 10 A continuous. Add 0.3% to the specified accuracy when measuring signals > 10 A to 20 A for 30 seconds maximum. After
measuring currents > 10 A, cool down the multimeter for twice the duration of the measured time before proceeding with low current measurements.
4. Only applicable for the U1232/U1233 Series
