1090 Portable Process Calibrator

The 1090 is a precision portable process calibrator that combines source and measurement functions for thermocouples, Pt100s, µV, mV & mA. It is a multifunction instrument that combines accuracy and durability with simple operation, making it ideal for process plant applications and field testing work.

Thermocouple Measurement and Simulation: Measure and simulate the temperature and mV characteristics of J, K, T, R, S, B, N and E thermocouples. The 1090 can be operated with or without internal cold junction compensation. 

Pt100 Measurement and Simulation: Based on 0.3850 alpha probe standard. Range is -200 °C to 700 °C.

Measurement and Source (µV, mV, and mA): Measurement ranges are 0 to ± 30 mV and 0 to ± 60 mA. Source ranges are 0 to ± 80 mV and 0 to 80 mA.

Temperature Units Selection: The display can be easily changed from °C to °F. The equivalent µV (thermocouples) and ohms (Pt100) can also be shown. 

24 V Process Loop Drive Mode: A process loop can be driven at 24 V and up to 60 mA by selecting the ‘Milliamp Source’ mode and setting it at 60 mA (or a lower level if required).

Practical user features

Features include an increment/decrement function that adjusts an output in fixed increments of temperature (for thermocouples), voltage or current. Three levels of increment are 0.1/1/10 for °C/°F, or 1/10/100 μV/μA for voltage or current. Lower increments mean higher setting resolution, enabling a more precise control of the output. This is useful when calibrating thermostat controllers that have tight specifications on hysteresis.

Further features are the memory recall and stepping functions. Up to 10 values can be stored and recalled at any time. The user can manually step through them in sequence or use continuous stepping (auto-step) at a selectable rate between 1 & 10 seconds/step.

1090 carry case

Built for field calibration work

The 1090 is a robust instrument used for field calibration work. It is supplied with a leather carry case that serves to protect the calibrator and features a folding front cover that enables full usage of the unit when housed.

Power is via an internal high capacity rechargeable metal hydride battery that can be recharged from the supplied external mains charger. An auto power-down feature helps conserve battery life by switching off the instrument if inactive for over 5 minutes. 

1090 Applications

The 1090 is a versatile multifunction field calibrator for testing and calibration of industrial process equipment. It can be used to measure a temperature sensor output to verify performance, or simulate sensor outputs at different temperatures to check transmitters and measuring devices.

In addition to thermocouple and RTD transmitter calibration, the 1090 provides a solution for process loop diagnostics, fault finding and maintenance. Troubleshoot 4-20 mA loops with mA measurement of a transmitter output, simulate a transmitter with mA source, and provide 24 V loop power.
