Fluke 12B/18 - Accuracy Specifications

English
Page 14
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:

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.
