Basic Features: Measurement and output accuracy is 0.02%, measurement is displayed as 5 digits, and output is displayed as 6 digits. Measurement function: DC voltage, DC current, frequency, on-off measurement, pressure Output function: DC voltage, DC current, analog transmitter, frequency, number of pulses, pressure Internal 24 V loop power supply to power the transmitter and simultaneous milliamp measurements Fast-responding switch test allows capture switch settings, resets, etc. 25% and 100% manual stepping, automatic stepping and automatic ramp output for DC current output Large-screen LCD multi-data display, can display simultaneously: DC current and % value It can be equipped with 43 pressure modules of different pressure ranges of APM series, which can display 5-digit pressure measurement with accuracy of 0.025% It has the function of automatic pressure zero adjustment; it has the function of testing the switch. It automatically locks the current pressure display value and the on/off state of the switch when the switch is off-pass or on-off. The operation performance is superior to the keyboard configuration, and the increase/decrease key of the output setting corresponds to the display setting value on the LCD. Panel calibration technology allows calibration without opening the case With white LED backlight, with automatic backlight off and automatic power off function, suitable for field use Measurement basic technical specifications [ applicable withinone year after calibration, 23 °C ± 5 °C, 35 ~ 70% RH, accuracy = ± (% of reading + range %)] |
