Inching............................................................ Three levels of increment, 0.1, 1 or 10 for °C/°F, and 1, 10, or 100 μV/μA for voltage/current.

......................................................................... The lowest of these represents the highest setting resolution and provides the most precise control of the output.

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).

Memory recall and step functions ............... 10 memory locations for non-volatile storage of values. Manual & AutoStep, rate adjustable from 1 to 10 sec/step.

General Specifications

Cold junction compensation ........................ Accuracy: 0.2 °C. Resolution: 0.1 °C.

Operating temperature ................................. 10 to 40 °C (15 to 105 °F).

Connections................................................... Industry standard 4 mm screw terminals.

Power.............................................................. A Ni-MH rechargeable battery pack gives approx. 60 hours continuous use. The mains recharger supplied

...................................................................... gives full recharge in 11 hours. To conserve battery life a user inactivity power-down feature is included.

Dimensions / weight...................................... H 235 x W 150 x D 75 mm, weight 1.2 kg.

Optional extras .............................................. Calibration certificates: Traceable (Factory) and Accredited (ISO 17025).

Ordering Information

1090.............................................................. Portable Process Calibrator

C177................................................................ Traceable calibration certificate (Factory)

C139................................................................ Accredited calibration certificate (ISO 17025)
