DC Voltage References:
usually zener-based references (such as Fluke 732B, Statronics VS4 etc). Standard cell reference calibrations are no longer offered.
DC Standard Resistors:
we cover the range from 0.1 mΩ to 5 TΩ.
DC Current Shunts:
we calibrate DC shunts up to 875 A
Standard Capacitors, Inductors, and AC Resistors:
these are normally calibrated at 1.59 kHz although we cover the range 40 Hz to 2 kHz at an increased uncertainty.
these include single-range thermal voltage converters (such as Fluke A55, which can be calibrated up to 70 MHz) or multirange instruments (such as Fluke 5790A, which are generally calibrated up to 1 MHz). AC-DC Current Shunts (such as a Fluke A40) are best calibrated in combination with the AC-DC voltage instrument with which they are used and can be calibrated up to 100 kHz.
DMM and Multi-Function Calibrators:
we cover 5½ to 8½ DMMs (such as HP3458A, HP34401A, Fluke 8506A, Datron 1281 etc) and calibrators with similar capability (such as the Fluke 5700A and Fluke 5500A families, Fluke 5100B etc).
