High accuracy Multifunction Process Calibrator

The H726 Multifunction Process Calibrator is a powerful, easy-to-use field calibrator. Use measure and source functions to test

Features: The H726 Multifunction Process Calibrator is a powerful, easy-to-use field calibrator. Use measure and source functions to test and calibrate almost any process parameter.

Loop Power Voltage: 24V Accuracy: 10% Maximum Current: 24 mA, Short-circuit protection

In addition to the functions listed in Table 1,the calibrator also has the following functions:

1. Split-screen display. The upper display allows users to measure volts, current, and pressure only.The lower display allows the user to measure and source volts, current, pressure, resistance temperature detectors, thermocouples, frequency,and ohms.

2. Thermocouple (TC) input/output terminal with cold junction temperature compensation,ambient temperature can be set and calibrate within the menu function.

3. Each parameters can manual and automatic stepping and ramping output, signal output can be arbitrarily set within the 0% and 100% of the value. (In addition to the pressure output)

4. In the configuration menu can be set manually : Power off time for Instrument\ Backlight off time\ Screen Contrast\ Cold junction compensation ON/OFF\HART resistence ON/OFF and ETC. You can also set the output amplitude and duty cycle for frequency manually in configuratiion menu.

5. Have calendar clock function,it can be calibrated in configuration menu.

6. It can store 8 sets of measurement and output data and call the showing at any time,all the settings and the functions of the last operation be auto-stored after power off.

7. The Calibrator and pressure module is hot-plugging, not need to turn off power, adaptive communications, abundant optional fitting.(Pressure module\Pressure pump\Adapter)

8. High capacity rechargeable battery pack, with power adapter,within integrated charge-management functions.

9. Novel shape,large screen dot-matrix graphic display, can display chinese characters,digital key to input personalized , make the operation more simple.
