The new MS7287 process calibrator

Ninety-nine equipment wholesale MS7287, ninety-nine instrument direct MS7287, ninety-nine instrument supply MS7287. MS7287 process calibrator multimeter whole circuit was designed by large-scale ASIC chips. It contains an internal 8-bit microprocessor, high precision and high stability operational amplifiers and analog to digital converters. Low power consumption, high precision display (40000 counts that is 34/5 bits), automatic range, can reduce operation and improve safety. Its technical performance in line Electric Type II, Type Ⅲ type electrical automation instrument calibration standards, the working environment in line with GB6587.1-86 "master environmental testing electronic measuring instruments" relevant provisions of the instrument group II. Backlight LCD display, the largest display 40,000 words, suitable for use in any lighting condition meter can output current to the transmitter and other equipment, can also simulate a transmitter output current. Built-in rechargeable NiMH battery pack, plenty of power, external replaceable. Step four ramp rates to choose from, in the case of one hand free, response speed test transmitter. When the meter measuring selectable Min / Max / Average / Hold / Relative measurement mode there are four current output range to choose from, corresponding to 0.05% accuracy, resolution 1μA, and also shows the percentage range of the instrument separately 24V power output. Output section: Function Range Accuracy source output current 0 ~ 20.00mA ± (0.05% + 5digit) 4 ~ 20.00mA ± (0.05% + 5digit) simulation output current 0 ~ 20.00mA ± (0.05% + 5digit) 4 ~ 20.00mA ± (0.05% + 5digit) loop supply output (voltage> 24V, with HART 250Ω resistor) 0 ~ 24.000mA ± (0.05% + 5digit) Current Regulation Mode Manual: Coarse (1mA), fine (0.0001mA) and step into the 25% automatic: Slow stepped slope, slowly stepped slope, rapid rate, full rate. Measurement: Functional Range Accuracy DC voltage 0 ~ 1000V ± (0.05% + 6digit) AC voltage 0 ~ 700V ± (1% + 40digit) resistance 0 ~ 40MΩ ± (0.1% + 10digit) frequency of 20Hz ~ 50KHz ± (0.05% + 2digit) DC current 0 ~ 400mA ± (0.05% + 10digit) AC current 0 ~ 400mA ± (1% + 10digit) DC current 0 ~ 10A ± (0.1% + 10digit) AC current 0 ~ 10A ± (1% + 10digit) Measurement, optional Min / Max / Average / Hold / Relative measurement function display also shows the percentage of value accounted for attachment range: Packaging: bag, carton (28 * 20 * 9), GW: 1.3KG use a manual; a product certificate; test line and an output line of each pair; a charger; 24V output wire set (red is positive, black is negative) PH digital electrode CPS11D-7BA21 PH digital electrode CPS11D-7BA2G PH digital electrode CPS11D -7AA21 PH electrode CPS11-1AA2ESA PH electrode CPS11-2AA2ESA PH electrode CPS11-2BA2ESA PH electrode CPS11-1AA2GSA
