The H705 handheld digital calibrator compared with FLUKE F705 Digital DC voltage up to 24V, mV up to 100mV, current up to 22mA signal source and measuring functions Brand New with 3 yr warranty 1. General information H-705 automation instrument field simulator is a handheld digital calibration instrument integrated with digital DC voltage, mV, current signal source and measuring functions featured with high precision, resolution, high reliability and anti-dropping. The instrument uses 22mm font-height large LCD with clear reading and is equipped with LED backlight for reading in dimly lighted site. The instrument can be powered by internal battery pack or external power adapter to deliver easier utilization. Instrument signal output and mA, mV measuring functions are designed mainly for field calibration and service of industrial automation field instrument, and is featured with high precision. It is an ideal signal source and testing tool for field metermen, computer distributed control system maintainers and meter installers. The circuit design of complete device takes large integrated circuit dual slope A/D converter as its core, which has functions of signal output and testing. Its technical characteristic conforms to automation instrument calibration standard Type II and Type III, while the operation environment conforms to regulations related to instrument Group II in GB6587.1-86 Environmental Tests Program for Electronic Measuring Instruments. 2. Functions and features ※LCD display with font height 22mm. ※ Over range displays “1”. ※ Power output 24V DC, which can serve as the working power of 2-wire instrument. ※0-10V, 0-20mV, 0-100mV, 0-20mA and 0-22mA DC signal output scales are available, which can serve as the input and output signal of type II and type III instruments and can simulate various of type II and type III instruments in field verification. ※200V, 20V, 200mV, 100mA and 20mA DC signal measuring scales are available, which can be used to measure the working voltage of the instrument and the input/output voltage signal and current signal of the instrument. ※ The instrument can working under condition of 24V power, output DC signal and measuring function simultaneously. ※The instrument has quadruple half digits LCD display, with the rotary switch, it can display the output value, measured value and unit. 3.
