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 ? ? 10 ?. The multimeter can capture intermittent measurements longer than 1 ms. 4. The accuracy of the 600 ? to 6 k? 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 M? and 60 M?, 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 ?A to 600 ?A 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.
