RTD Process Calibrator w/Patented RTD Wire Detection, Model 311 by PIE

Calibrate with ease with resolution to 0.1 F/C & accuracy to 0.2C Source and read multiple RTD curves plus ohms. Platinum 100 ohms: 1.3850, 1.3902, 1.3916,13926. Platinum 1000 ohms: 1.3850, 1.3750. Copper 10 & 50 ohms. Nickel 120 ohms, 0.00 to 4001.0 ohms Comes with NIST certificate, rubber boot, carrying case, 2 red & 2 black leads w/banana plugs & spade lugs, 4-AA batteries Automatically detect 2, 3, & 4 wire connections Guaranteed compatible with all instrumentation Instantly select 3 outputs with the EZ-CHECK switch Easily find trip points w/2 speed EZ-DIAL knob & auto stepping Easily change RTD types and F/C scale Verify RTD temperature & output Turn on the backlight to easily read in dark areas The PIE 311 is designed to be easily used. You can check and calibrate all your RTD instruments and measure RTD sensors. You have automatic indication of connections on the display for simple hook-ups. And now you can stop carrying around a decade box and RTD resistance tables. The PIE 311 works with the RTDs you use including Platinum 100 (alpha = 3850, 3902, 3926) and 1000 (alpha = 3850, 3750) Ohm, Copper 10 & 50 Ohm and Nickel 120 Ohm. Easily set any value quickly to within 0.1C with the adjustable digital potentiometer "DIAL" plus store any 3 temperatures for instant recall with the EZ-CHECK switch. User can quickly choose between 2, 3, 5, 11 and 21 steps to automatically increment the output in 100%, 50%, 25%, 10% or 5% of span. You can also select the step time to match your system from 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 60 seconds. With patented technology, the PIE 311 trouble shoots sensor connections to find  broken wires. You can connect your 2, 3, or 4 wire RTDs and the PIE 311 will automatically detect connections and measure the RTD in degrees C/F. The secondary display will show the resistance value corresponding to the RTD temperature.  To Order the model below scroll to the top of the page then click on ADD TO CART button  PART NUMBER DESCRIPTION CL-PI-311 RTD PROCESS CALIBRATOR w/RTD WIRE DETECTION     Datasheets and User Manuals PIECAL 311 Universal RTD Calibrator Datasheet PIECAL-311 Universal-RTD-Calibrator Operating Instructions   SPECIFICATIONS ACCURACY: +/-(0.015% of reading + 0.05 Ohms) TEMPERATURE DRIFT: +/- 0.01% of span outside of 23C +/-10C (73C +/-18F) OPERATING TEMPERATURE RANGE: -25 to 60C (-10 to 140F) RH RANGE: 10% <RH <90% (0 to 35C) non-condensing; 10% <RH <70% (35 to 60C) non-condensing DIMENSIONS: 5.63 x 3.00 x 1.60 in (143 x 76 x 41 mm) WEIGHT: 12.1 oz (0.34 kg) including boot & 4-AA batteries BATTERY LIFE: 50 hrs w/ low battery indication (1 hr left) PROTECTION AGAINST MISCONNECTION: over-voltage protection to 60 V dc (rated for 30 seconds) DISPLAY: high contrast graphic LCD.
