  1. 724 Temperature Calibrator • Powerful, yet easy to use • Simultaneously source / simulate and measure: • mA measure • Vdc • RTDs (7 types) • TCs (10 types) • Loop power supply to power transmitters

  2. 724 MPC: Features/Benefits • Dual measure/source display • Set 0% and 100% range values • 0%, 100%, and 25% step keys • Auto stepping, auto ramping temperature and voltage • Memory for frequently used setups • Battery access without breaking calibration seal

  3. Process Tools724 Temp Upper Display Controls Measure Volts dc Turn on 24V loop power with mA measure Measure mA dc Upper Display Terminals for measure

  4. Process Tools724 Temp Lower Display Controls Measure or Source • Selection buttons for: • V or mA • Ohms • RTD and type • TC and type Arrow keys set source values, left right to select digit, up down to change value Lower Display Terminals TC connectors

  5. Process Tools724 Temp Store and Recall up to eight test setups Back-light Set 0% and 100% values (span). Do quick Span Check or Step in 25% steps up or down. Press and hold 0% and 100% to set displayed value Select slow ramp, fast ramp, and step function on any sourced parameter based on 0% and 100% settings Features

  6. 2 2 5 2 zero span Temperature Calibration • Set the span 0%-100% • Use 25% step keys to calibrate • Simulation of different types of Thermocouples and RTDs • Accurate and high resolution current measurements • 24V loop power supply to test independent of the loop

  7. Special function, battery save • The calibrator comes with the Shut Down mode enabled for a time duration set to 30 minutes • Displayed for about 1 second when the calibrator is initially turned on • To disable the Shut Down mode, press simultaneously. • To enable the mode, press simultaneously. • To adjust the time duration, press simultaneously, then press to adjust the time between 1 and 30 minutes.

  8. Save and recall setups • Configure the calibrator • Set 0% and 100% source values • Press STORE SETUP • Press left and right arrows to select locations 1-8 (top of display) then press STORE SETUP again to save as desired set up number • To recall setup press RECALL • Left and right arrows to select setup 1-8 then press RECALL to recall the setup Store and Recall up to eight test setups

  9. Troubleshoot and Calibrate Current Loop instruments used in industrial processes 2200 ºC What Process Calibrators Do? Current Loop 4 to 20mA analog (2 wire) signal for communication between instruments, controllers, and indicators Instrumentation Transmitter SENSOR 2 2 5 2 span zero Controller PLC, DCS Indicator CONTROL ELEMENT

  10. 2200 ºC Loop Supply ZERO SPAN Measure Loop Current • Loop Calibrators measure external current • Current and % readout • 1 microamp resolution, high accuracy • Calibrator or system Loop supply provides power Sensor 4 to 20 mA Readout / Controller DCS / PLC / Recorder 2 Wire Transmitter

  11. ZERO SPAN Measure mA with internal loop supply • Current or % readout • 1 microamp resolution • Provides loop power to operate transmitter • 24 VDC output 4 to 20 mA

  12. 2200 ºC ZERO SPAN Simulate (source) an RTD • Select RTD type • Set Temperature • Check indicator device RTD Sensor 4 to 20 mA

  13. ZERO SPAN Simulate (source) a TC • Select TC type • Set Temperature • Check indicator device 4-20mA OUTPUT
