Feature(may vary by option.)
●Your unit is calibrated prior to shipment with a new NIST-traceable calibration Certificate with data
●The NIST calibration provides you assurance your instrument meets manufacturer’s specifications. Your instrument is ready to use day one meeting most quality system standards
●It provides source and read milliamp functions along with power and measure; and two wire transmitter simulations
●The Meriam M334 is a state of the art, highly reliable, rugged and easy to use milliamp calibrator
●It has the functions necessary to perform all the required maintenance and calibration tasks of virtually any 4-20ma loop
[with NIST Certificate]
Description
The M334 is functionally equivalent to similar calibrators with many additional benefits. These improvements include better long term stability, accuracy, reliability and ruggedness including significantly improved battery life. The combined improvements allow the Meriam M334 to meet or exceed all of the expected performance and functions of similar products. The M334 will also exceed the performance of many higher cost calibrators and meet today’s most demanding requirements while maintaining the familiar, time proven reliability and ease of use of similar calibrators. All milliamp (mA) loop functions - source 0 to 24 mA (-25 percent to 125 percent), read 0 to 52 mA (-25 percent to 300 percent), simulate 2-wire transmitters, power and measure 2-wire transmitters. Accuracy to better than 0.025 percent (+/-1/2 LSD) - within +/-0.005 mA from 4 and 20 mA EZ-checks. Large high contrast graphic display - viewable in all lighting conditions and angles. Read voltage function: read 0 to +/-99.99 VDC. EZ-dial knob - easily adjust output by 0.01 mA (0.01 percent). EZ-Check 3-position slide switch - instantly output 4.00 or 20.00 mA calibration values, adjustable in all 3 positions for easy valve testing, rugged, unbreakable with splash protection. Uses 4 standard "AA" alkaline batteries - battery life up to 70 hours of normal usage, easily accessible battery compartment. Overload protected - 135 vrms protection, fuse-less protection from accidental misconnection. Compact, lightweight and rugged - small in size with heavy protective rubber boot. Ranges and resolution: 0 to 24 mA Full Span or -25 to 125 percent of 4-20 mA. Accuracy: EZ Check(s) at 4 and 20mA(1) - = +/-0.025 percent of span at 4.00 mA and 20.00 mA (+/-0.005 mA), 0.0 to 24.00 mA - = +/-0.05 percent of 24.00 mA Span (+/- 0.01 mA), noise - = +/-0.005 mA of reading. Temperature effect: = +/-0.005 percent / degree C of FS. Loop compliance voltage: = 24 DCV at 20.00 mA.
