SPECIFICATION / THÔNG SỐ KỸ THUẬT CƠ BẢN

The following accuracy is specified for one single channel (channel 1 or channel 2). If dual channels are used at the same time, additional % of accuracy should be added to the listed accuracy. Please refer to the supplemental dual channels specification. The following accuracy is also specified for the ZEROED (relative) value. The accuracy is given as ±% of reading ± number of least significant digits.

AC Voltage: The accuracy of ACV or AC mV is specified for 5%-100% of range from 20Hz–10KHz, average sensing. Input Impedance is 10M , and overloaded protection is AC 1000V for all range. Accuracy is also specified for single channel (channel 1 or channel 2). If dual channels measurements are performed, additional specification of accuracy will be introduced. Please refer to the supplemental dual channels specification. Due to the wide bandwidth, the reading might not be zero when no inputs present. But the residual reading does not affect the listed accuracy. If the AC reading is less than 100 least significant counts, it is set to zero by the unit.
