Notes for voltage specification. 1. The accuracy is specified after NULL function is used to zero out thermal effect (by shorting test leads). 2. The temperature coefficient for 6 V range is 0.075 x (specified accuracy) / °C (from –20 °C to 18 °C or 28 °C to 55 °C). 3. The accuracy is specified for 10 MΩ (nominal) input impedance. 4. Overload protection for 60 mV and 600 mV ranges: 1000 Vrms for circuits < 0.3 A short circuit current. Overload protection for other ranges: 1000 Vrms. B. Notes for current specification 1. Current can be measured up to 440 mA continuously. Maximum of 20 hours for measuring current more than 440 mA. 60 mA and 600 mA ranges have thermal effect of 0.35 µA/mA to be offset after current applied to these ranges. Cool down the meter for at least 6 seconds if 100 mA was applied, and at least 3 minutes if 600 mA was applied; or alternatively use the NULL function to zero-out thermal effect with open test lead before measuring the signal. 2. Current can be measured up to 10 A continuously. Maximum of 30 seconds for measuring current more than 10 A to 20 A, add 0.3 % to specified accuracy. The multimeter needs to be cool down after measuring current that is more than 10 A. Cool down the meter for twice the duration of the measured time and use NULL function to zero-out thermal effect before proceeding with lower current measurement. 3. 600 µA to 60 mA ranges (connection with mA terminal) overload protection by 10 x 35 mm, 440 mA/1000 V, 10 kA minimum fast-acting fuse. 4. 6 A and 10 A ranges (connection with A terminal) overload protection by 10 x 38 mm, 11 A / 1000 V, 20 kA minimum fast-acting fuse. 5. Ensure good ventilation and no heat element close to the meter. C. Notes for diode test specification 1. Overload protection: 1000 Vrms for circuits < 0.3 A short circuit current. 2. Built-in buzzer sounds when reading is below 0.05 V approximately, and single tone for normal forward-biased diode or semiconductor junction as 0.3 V ≤ reading ≤ 0.8 V. 3. The maximum threshold voltage display is less than +3.1 V. D. Notes for resistance/audible Continuity specification 1. Maximum open voltage: < +2.7 V 2. Built-in buzzer sounds as transient when resistance less than 25 ± 11 Ω. It may capture the intermittent for longer than 1 ms. 3. The accuracy is specified after Math Null, which is used to subtract the test lead resistance and the thermal effect. Ensure good ventilation and no heat element close to the meter. 4. For 60 MΩ and 600 MΩ ranges, the R.H. is specified for < 60 % at 30 °C. 5. Only available in U1282A 6. For 600 MΩ range: temperature coefficient is 0.1 x (specified accuracy) / °C (from –20 °C to 18 °C or 28 °C to 55 °C). |
