Accuracy Specifications - Fluke 15B Calibration Manual

Accuracy Specifications

Accuracy is specified for 1 year after calibration, at operating temperatures of 18 °C to
28 °C, relative humidity at 0 % to 75 %.
Accuracy specifications take the form of: ±([% of Reading] + [Number of Least
Significant Digits])

Duty Cycle
1. Manual Range only
2. Diode test open circuit test voltage is 1.1 V to 1.6 V and short circuit current is < 0.6 mA (typical).
3. Temperature specifications do not include thermocouple errors. After inserting the thermocouple plug into the meter, allow several
minutes for thermal stabilization.
4. Specifications do not include errors due to test lead capacitance and capacitance floor (may be up to 1.5 nF in the 50 nF range).
For the 17B, errors can be reduced by using the relative feature.
5. For values between 10% and 90% duty cycle at 50 Hz.
