Product Description

• Easy to use

With the PIECAL 311 you can check & calibrate all

your RTD instruments and measure RTD Sensors.

Automatic indication of connections on the display for

simple hookups.

• Take it 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 decade box and RTD

resistance tables. The PIECAL 311 works with the

RTDs you use including Platinum 100 (alpha = 3850,

3902, 3926) & 1000 (alpha = 3850, 3750) Ohm,

Copper 10 & 50 Ohm, Nickel 100 and 120 Ohm.

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 RTD inputs of smart

transmitters, PLCs, DCS and multichannel recorders and verify their outputs or

displays. Works with older instruments with fixed excitation currents and newer

multichannel instruments that switch the excitation current between input channels.

• Measure RTD Sensors

Trouble shoot sensor connections and find broken wires with patented technology. Connect your

two, three or four wire RTDs and the PIECAL 311 automatically detects the connections and

measures the RTD in degrees C or F. Secondary display shows the resistance value

corresponding to the RTD temperature.
