Introduction

The 5560A/5550A/5540A Calibrators (the Product or the Calibrator) addresses a wide calibration
workload that includes 6.5 digit bench Digital Multimeters (DMMs), and comes with internal and
external features that protect it against damage and make it easier to transport for on-site or mobile
calibration. The Product, shown in Figure

, can also be fully automated with MET/CAL

®

.

The Product is a fully-programmable precision source for:
• DC voltage from 0 V to

±

1020 V

• DC current from 0 A to

±

30.2 A

• AC voltage from 1 mV to 1020 V
• AC current from 10

μ

A to 30.2 A

• AC waveforms include sine wave and square wave.
• Synthesized Resistance values from a short circuit to 1200 M

Ω

• Synthesized Capacitance values from 220 pF to 120 mF
• Synthesized Inductance values from 12

μ

H to 120 H (Inductance not available on 5540A).

• Simulated output for 10 types of Resistance Temperature Detectors (RTDs)
• Simulated output for 17 types of thermocouples
• Simulated power output (not available on 5540A)

Note

All images shown in this manual are the 5560A unless noted otherwise.
