Universal meter 81780 with manual range for each measurement allows you to make basic electrical measurements Basic measurements: • AC voltage measurement: A C. 0-500 V • DC voltage measurement: D C. 0-500 V • DC current measurement: D C. 0-5 A • resistance measurement: 0-2 MO • diode test: IF 1 m A, UR 1. 5 V Additional measurements: • h Fe transistor test: 0-1000, built-in measurement socket Measurement accuracies: Example of accuracy determination for AC voltage measurement Calculation for the measurement result: 235 V • The measurement accuracy of the 81780 meter for this range is: ±(1. 2% + 10), resolution of 1 V • calculation of measurement error formula: (measurement result x 2%) + 10 x resolution • calculation: (235 x 1. 2%) + 10 x 1 = 2. 82 + 10 = 12. 82 V Result including measurement error for 235 V indication = 235 ± 12. 82 V* • Result including measurement error for DC voltage measurement indication: 12 V = 12 ± 0. 08 V For a table with the resolution and accuracy for a given measurement, please refer to the user's manual. *The 81780 meter does not have a true rms measurement function, so the above result is true only for a normal sine waveform Additional information: • LCD display, maximum displayed result: 1999 • measurement probes included • design with overload protection • plastic housing • low battery indicator • power supply: 9 V (6 F 22) battery Attention! When measuring unknown values with a meter with manual range change using the dial, take measurements sequentially from the largest range up to the range giving the most accurate result - otherwise you risk damaging the device.
