Multifunctional process calibrator for pressure measurement YHS726
Introduction:
The YHS726 Multifunction Process Calibrator is a powerful, yet easy-to-use field calibrator. Use the measure and source functions to test and calibrate almost any process parameter.
Small, streamlined shape makes it easy to carry.
Rugged, reliable design stands up to field use.
Easy to read measure/source screen lets you view input and output simultaneously.
Measure volts, mA, RTDs, thermocouples and ohms to test sensors and transmitters.
Source/simulate volts, mA, thermocouples , RTDs, frequency, ohms, and pressure to calibrate transmitters.
Support flow meter testing with frequency and CPM functions.
Perform fast linearity tests with auto- step and auto-ramp features.
Power transmitters during test using loop supply with simultaneous mA measurement.
Handling of fast pulsed RTD transmitters and PLCs, with pulses as short as 10 ms *Store frequently used test setups for later use.
Backlight lets you work in poor light.
Large battery capacity of four AA cells.
Battery door for easy changes.
Feature:
A split-screen display. The upper display allows users to measure volts, current, and only. The lower display allows the user to measure and source volts, current, resistance temperature detectors, thermocouples and ohms.
A thermocouple (TC) input/output terminal with cold junction temperature compensation, ambient temperature can be set and calibrate within the menu function.
Each parameters can manual and automatic stepping and ramping output, signal output can be arbitrarily set within the 0%,25% and 100% of the value.
In the configuration menu can be set manually : Power off time for Instrument Backlight off time Screen Contrast Cold junction compensation ON/OFFHART resistence ON/OFF and ETC.
Have calendar clock function, it can be calibrated in configuration menu.
It can be 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.
High capacity rechargeable battery pack, with power adapter, within integrated charge-management functions.
Novel shape, large screen dot-matrix graphic display, can display Chinese characters, digital key to input personalized , make the operation more simple.
