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.
