FLUKE 743B Documenting Process Calibrator

The Fluke 743B Documenting Process Calibrator is a battery-powered, hand-held instrument that measures and sources electrical and physical parameters. The calibrator lets you troubleshoot, calibrate, verify, and document your work on process instruments. It has an analog display to make it easy to read measurements when the input is unstable. Thermocouple (TC) (Types E, N, J, K, T, B, R, S, C, L, or U) input/output jack and internal isothermal block with automatic reference-junction temperature compensation or manually record an external temperature reference. The ability to automatically log up to 8,000 data points and a serial computer interface for uploading/downloading tasks, lists, and results.

*This is a Web introductory price for one calibration of the FLUKE 743B. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

dBm
dBm (sometimes dBmW) is an abbreviation for the power ratio in decibels (dB) of the measured power referenced to one milliwatt (mW). Zero dBm equals one milliwatt. A 3 dB increase represents roughly doubling the power, a 3 dB decrease, the power is reduced by about one half.

Millimeter-wave
Millimeter-wave is a term that generally refers to frequencies of 26.5 GHz and above. That is where signal wavelengths fall below approximately 10 mm, and thus the terminology changes from centimeters to millimeters.

Power Repeatability
Power Repeatability is the random uncertainty in reproducing the power level after changing and re-setting the power level. The power repeatability is ± half the span (in dB) between the highest and lowest actual power. Note: - The long-term power repeatability can be obtained by taken the power repeatability and power stability into account.

Stability
Stability is the extent to which a specified property, characteristic, or parameter of a substance, device, or apparatus, remains fixed with the passage of time or with varying environmental conditions.
