Universal meter 81780 with manual range for each measurement allows for basic electrical measurements.

Basic measurements:

• measurement of alternating voltage: A.C. 0-500 V
• measurement of direct voltage: D.C. 0-500 V
• measurement of direct current intensity: D.C. 0-5 A
• measurement of resistance: 0-2 MΩ
• diode test: I_F 1 mA, U_R 1.5 V

Additional measurements:

• transistor hFe test: 0-1000, built-in measuring socket

Measurement accuracy:

Example of determining accuracy for measuring alternating current voltage AC. Calculations for the measurement result: 235 V

• meter 81780 accuracy for this range is: ±(1.2% + 10), resolution 1 V
• measurement error calculation formula: (measurement result x 2%) + 10 x resolution
• calculations: (235 x 1.2%) + 10 x 1 = 2.82 + 10 = 12.82 V

Result with measurement error for indication 235 V = 235 ± 12.82 V*

• result with measurement error for indication of direct voltage measurement: 12 V = 12 ± 0.08 V

Table with resolution and accuracy for a given measurement can be found in the user manual.

*Meter 81780 does not have true rms measurement function, so the above result is accurate only for a correct sinusoidal waveform.

Additional information:

• LCD display, maximum displayed result: 1999
• measurement probes included
• construction with overload protection
• plastic housing
• low battery indicator
• power supply: 9 V battery (6F22)

Attention!

When measuring unknown values using a meter with manual range change using a dial, measurements should be performed sequentially from the largest range to the range that gives the most accurate result - otherwise, there is a risk of damaging the device.
