Note:

① For the 1   mV, 10 mV, and 100 mV ranges, if zeroing is not performed, an additional zero   output error of 100 nV should be considered.

② The 100 V   range is only supported on CH1 output.

Maximum Power Consumption

100 W

Warm-Up Time

At least 30 minutes, the preheating   time after shutdown should be no less than twice the shutdown time.

Working Conditions

Temperature: 20 ± 2 °C, the   ambient temperature change during calibration should not exceed 1 °C;

Humidity: ≤ 75%.

Others: During calibration, the   device and the objects around the meter under test remain relatively still to   reduce disturbance, and there is no electromagnetic interference and   mechanical vibration that significantly affects the measurement.

Storage Environment

Temperature: 0°C～50°C

Humidity: 10%R·H～90%R·H, no condensation

Altitude

< 2000 m

Communication Interface

RS232×1, LAN×1, USB×1
