Specifications

Accuracy is specified for a period of one year after calibration, at 18°C to 28°C (64°F to 82°F) with relative humidity to 90%. AC conversions are ac-coupled, average responding, and calibrated to the rms value of a sine wave input. Accuracy specifications are given as follows:

±([% of reading] + [number of least significant digits])

1.The 4000 mV range can be entered only in manual range mode. Use the 4000 mV range with accessories.

2.The beeper is guaranteed to come on at <25Ω and turn off at >250Ω. The meter detects opens or shorts 250 μs.
