Fluke quality is always within your reach
Your job requires that you have a rugged, reliable and accurate digital multimeter. The Fluke 15B+ digital multimeter does all that and more. Easy to use with one hand, even with gloves on, the Fluke 15B+ offers everything you need.
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).

| 1All ac, Hz, and duty cycle are specified from 1% to 100% of range. Inputs below 1% of range are not specified. 2Typically, open circuit test voltage is 2.0 V and short circuit current is <0.6 mA. 3Specifications do not include errors due to test lead capacitance and capacitance floor (may be up to 1.5 nF in the 40 nF range). |
