Typical performance for current ≤ 30 µArms. 2. Current can be measured up to 440 mA continuously. Maximum of 20 hours for measuring current more than 440 mA. 3. 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. 4. Input current < 3 Arms. 5. These specifications are for typical performance. 6. For current < 3 Arms and < 5 kHz. 7. Additional error when Frequency is more than 30 kHz: 0.1 of least significant digit x square of frequency. The bandwidth of U1281A is up to 30 kHz only. Frequency Counts of least significant digit Formula Additional error 30 kHz 0.1 0.1 x 30 x 30 90 50 kHz 0.1 0.1 x 50 x 50 250 100 kHz 0.1 0.1 x 100 x 100 1000 8. 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. 600 µA to 600 mA ranges (connection wth µ.mA terminal) overload protection by 10 x 35 mm, 440 mA / 1000 V, 10 kA minimum fast-acting fuse. 9. Ensure good ventilation and no heat element close to the meter. |
