Product overview: Fluke 714B Thermocouple Calibrator

High accuracy thermocouple temperature calibration the easy way

Fluke 714B is a handheld, battery-operated instrument that measures and sources a variety of thermocouple types and millivolts. It can calibrate a linear thermocouple transmitter with the mV source function and also measure mA while sourcing temperature. It also provides linear ramp and 25% step auto ramp functionality based on 0% and 100% settings for performing quick, linearity checks.

Designed for calibration professionals

With the intelligent shutdown feature the Fluke 714B remembers settings when powered down so you can quickly replicate tests after powering back up. The calibrator also has one-year and two-year specifications, along with a traceable certificate of calibration. Combine that with its rugged construction, a backlit display, and easy to use interface and you have an ideal test tool for temperature calibration professionals who want a highly accurate, single–function thermocouple temperature calibrator.

I am trying to use the 714B Thermocouple Calibrator as a K type SOURCE. Why does the calibrator have 30mv peak to peak spikes at 1.42KHz on it's output? Spikes are a large part of the signal. Should be DC. Same issue, 2 units.
