24V Power Voltage Loop Multifunction Process Calibrator with Short-circuit Protection , YHS-724
Quick Detail:
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
Large battery capacity of four AA cells ；Battery door for easy changes
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% 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/OFF, HART, resistance, 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
