PIECAL Automated RTD Calibrator

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.

Features

• 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. Or use like a decade box from 0.00 to 410.00 and from 410.0 to 4001.0 Ohms.
• Fast calibration 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 No competitor's calibrator is compatible with as many 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.
• Evolutionary design PIECAL Calibrators are designed and built by members of the same team that designed and built the calibrators manufactured by Fluke* under the Altek* label. The PIECAL 311 improves upon other brands by including a rubber boot, tilt stand, backlit display with larger digits, rugged switches and a battery compartment for fast battery changes.
