Appa 507 The APPA 507 is a portable digital process calibrator with a multimeter function for generating and measuring direct current up to 24 mA. For the direct power generation, it is also possible that the percentage values, depending on the set current (0% = 4 mA, 100%=20mA). The APPA 507 also enables the measurement of the current, which is generated by an external converter to measure or a current converter to simulate. The APPA 507 corresponds to the safety standard IEC/EN 61010-1 with double insulation and overvoltage category CAT III lOOOV I CAT IV 600 V. Each function can be comfortably directly by the function buttons on the control panel selected. The APPA 507 is the ideal solution for the most common industrial applications and their use in laboratory areas. Highlights & Details CAT III 1000 V, CAT IV 600 V Features Dual Display, car AC, DC and AC + DC voltage-mode It can be extended with an external voltage source. Optically isolated USB interface, including software Auto Backlight 4-20mA DC power source and reference encoder function (HART communication compatible)
