Fluke 5502A Multi-Product Calibrator

Overview

Fluke 5502A is a transportable multi-product calibrator engineered for calibration teams that need laboratory-grade accuracy without being tied to a fixed bench location. Beyond the DC/AC voltage, current, resistance, and capacitance functions common to multi-product calibrators, the Fluke 5502A adds full thermocouple and RTD temperature simulation, covering B, C, E, J, K, L, N, R, S, T, and U type thermocouples plus multiple Pt385, Pt3926, Cu427, and PtNi120 RTD curves, making it a genuine one-box solution for electrical and temperature calibration labs alike.

With fast quotation turnaround and technical support, Seven Star LLC proudly supplies the Fluke 5502A to calibration laboratories and process instrumentation teams across Oman and the GCC, backed by genuine factory warranty, technical application support, and access to Fluke’s calibration software ecosystem for labs standardizing electrical and temperature traceability under one accredited program.

Operating Principle

The Fluke 5502A combines a precision DC/AC signal-generation stage with a dedicated thermocouple and RTD emulation circuit, so the same chassis can source a stable voltage or current on one test and emulate the millivolt output of a Type K thermocouple or the resistance curve of a Pt100 RTD on the next, without external cold-junction compensation hardware. Internal cold-junction sensing corrects the simulated thermocouple output automatically, which is what allows the unit to hold traceable accuracy when used away from a controlled lab environment — a capability that matters for teams calibrating field transmitters in situ rather than pulling every device back to a central lab.

On the electrical side, closed-loop feedback regulation maintains DC voltage to ±1020V, AC voltage from 1 mV to 1020V across 10 Hz to 500 kHz, current to 20.5A (extendable to 120A AC with the optional 52120A transconductance amplifier), resistance to 1100 MΩ, and capacitance from 220 pF to 110 mF. The practical consequence is that one calibrator, one set of traceability certificates, and one technician can cover the electrical and temperature verification of a mixed instrument population — multimeters, RTD transmitters, thermocouple readouts, and process indicators — in a single site visit.

Engineering Design of the Fluke 5502A

The Fluke 5502A is built into a ruggedized, ergonomically handled enclosure specifically designed for transport between calibration sites, with removable access doors that expose the rear connection panel for field servicing without full disassembly. Dual backlit alphanumeric displays present the source value on one screen and reference/error readout on the other, letting a technician confirm as-found and as-left readings side by side during an as-found/as-left calibration procedure.

Input and output terminals are grouped by function — normal 4-wire voltage/current binding posts, auxiliary sense terminals, a dedicated thermocouple/RTD terminal block, and a BNC scope-output connector for the optional 300 MHz or 600 MHz oscilloscope calibration module — keeping wiring changes fast during multi-function test sequences. RS-232 and IEEE 488 (GPIB) interfaces are both provided as standard, giving labs a choice of legacy GPIB-based automated test systems or simpler serial control scripts.

Key Features

The Fluke 5502A pairs electrical sourcing with temperature simulation in a single transportable chassis. Its principal capabilities include:

• Sources DC voltage to ±1020V and AC voltage from 1 mV to 1020V across 10 Hz to 500 kHz for wideband voltmeter calibration.
• Delivers DC and AC current to 20.5A, extendable to 120A AC with the optional 52120A transconductance amplifier for high-current clamp meter work.
• Simulates eleven thermocouple types (B, C, E, J, K, L, N, R, S, T, U) with automatic internal cold-junction compensation for field-accurate temperature calibration.
• Sources RTD resistance curves across multiple Pt385, Pt3926, Cu427, and PtNi120 configurations for verifying RTD transmitters and readouts.
• Generates resistance to 1100 MΩ and capacitance from 220 pF to 110 mF for ohmmeter and capacitance meter verification.
• Offers optional 300 MHz or 600 MHz oscilloscope calibration for labs that also maintain bench and field oscilloscopes.
• Communicates over both RS-232 and IEEE 488 (GPIB), supporting legacy automated calibration systems as well as modern scripted control.
• Ships in a transportable, ergonomically handled enclosure with removable access doors built for repeated on-site calibration visits.

Industrial Applications

In Oman’s oil and gas production facilities, power generation plants, and district cooling networks, calibration technicians rely on the Fluke 5502A to verify both the electrical instrumentation and the temperature transmitters distributed across a single process unit without swapping calibrators between tasks. Its combined electrical and thermocouple/RTD capability is particularly valuable for turnaround and shutdown work at refineries and petrochemical complexes, where hundreds of temperature and electrical loops must be verified within a tight maintenance window. The transportable enclosure suits field calibration teams serving desalination plants, cement works, and marine terminals across the Sohar and Salalah industrial zones, where equipment cannot always be pulled offline and shipped to a central laboratory.

With regional stock and engineering support in Muscat, Seven Star LLC distributes the Fluke 5502A to calibration laboratories and industrial end users throughout the Sultanate of Oman, Muscat, and the wider GCC, supporting hospital biomedical engineering departments, hospitality-chain facilities teams, and pharmaceutical manufacturers that all depend on accredited temperature and electrical calibration for compliance. Seven Star LLC’s regional stock and factory-trained technical support let calibration teams in Sohar, Salalah, and Muscat deploy a 5502A on short notice rather than waiting on an international import cycle.
