Universal meter 81783 with manual range for each measurement allows for basic and advanced electrical measurements. An additional protection against mechanical damage is the so-called holster - a rubber cover stretched over the device housing.
Basic measurements:
- measurement of alternating voltage: A.C. 0-600 V
- measurement of direct voltage: D.C. 0-600 V
- measurement of alternating current intensity: A.C. 0-10 A
- measurement of direct current intensity: D.C. 0-10 A
- resistance measurement: 0-200 MΩ
- diode test: IF 1 mA, UR 2.8 V
- circuit continuity test: 0-30 Ω
Additional measurements:
- measurement of capacitor capacity: 0-20 μF
- transistor hFe test: 0-1000, built-in measuring socket
Measurement accuracy:
Example of determining accuracy for the measurement of alternating current voltage AC. Calculations for the measurement result: 235 V
- the accuracy of meter 81783 for this range is: ±(1.2% + 5), resolution 1 V
- error calculation formula: (measurement result x 1.2%) + 5 x resolution
- calculations: (235 x 1.2%) + 5 x 1 = 2.82 + 5 = 7.82 V
Result considering the measurement error for reading 235 V = 235 ± 7.82 V*
- result considering the measurement error for reading direct voltage measurement: 12 V = 12 ± 0.08
- result considering the measurement error for reading alternating current intensity measurement: 8A = 8 ± 0.26 A*
The table with resolution and accuracy for a given measurement can be found in the user manual.
*Meter 81783 does not have true rms measurement function, so the above result is the real effective value of AC voltage only for a correct sinusoidal waveform.
Built-in functions:
- DATA HOLD - maintaining the currently measured value on the display
Additional information:
- LCD display, maximum displayed result: 1999
- audible signal in circuit continuity test for resistance below 30 Ω
- automatic switching from diode test to continuity test for circuit resistance below 30 Ω (no possibility to set the meter only to diode test)
- includes measurement probes
- construction with overload protection
- ABS housing + holster, i.e. rubber housing protecting the meter from mechanical damage
- automatic meter shutdown
- 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.
