PIECAL 422

Automated Thermocouple Calibrator

Operating Instructions

Product Description

• Easy to use

With the PIECAL 422 you can check & calibrate all

your thermocouple instruments and measure

thermocouple sensors.

• Take it without into the shop, plant or field

Carry it without worry - it comes protected with a

rubber boot and rugged, low profile switch. Easy to

operate even in the dark areas of the plant with the

backlit display.

• Calibrate directly in temperature (°C & °F)

Stop carrying around a millivolt source and

thermocouple tables. The PIECAL 422 works with the

thermocouples you use including types J, T, E, K, R,

S, B, N, G, C, D, L (J-DIN), U (T-DIN) and Platinel II.

Easily set any value quickly to within 0.1° with the

adjustable digital potentiometer “DIAL” plus store any

three temperatures for instant recall with the

EZ-CHECK™ switch.

• Calibrate quickly with automatic output stepping

Choose between 2, 3, 5, 11 and 21 steps to

automatically increment the output in 100%, 50%,

25%, 10% or 5% of span. Select the step time to

match your system from 5, 6, 7, 8, 10, 15, 20, 25, 30

and 60 seconds.

• Compatible with all process instruments

Connect directly to the thermocouple inputs of smart

transmitters, PLCs, DCS and multichannel recorders

and verify their outputs or displays.

• Measure Thermocouple Sensors

Trouble shoot sensor connections and find broken wires. The PIECAL 422 measures the

thermocouple in degrees C or F. Secondary display shows the millivolt value corresponding to

the thermocouple temperature as well as the cold junction temperature measured by the

calibrator.
