Universal meter 81784 with manual range for each measurement allows for basic and advanced electrical measurements. Built-in additional measuring sockets facilitate measurements of capacitors and transistors, among others. 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
• measurement of resistance: 0-200 MΩ
• diode test: I_F 1 mA, U_R 2.8 V
• circuit continuity test: 0-30 Ω

Additional measurements:

• measurement of capacitor capacity: 0-20 μF
• frequency measurement: 0-20 kHz
• temperature measurement: -40 to 400 °C
• 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

• meter 81784 accuracy for this range is: ±(1.2% + 5), resolution 1 V
• measurement 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 measurement error for indication 235 V = 235 ± 7.82 V*

• result considering measurement error for indication of direct voltage measurement: 12 V = 12 ± 0.08 V
• result considering measurement error for indication of alternating current intensity measurement: 8 A = 8 ± 0.26 A*

A table with resolution and accuracy for a specific measurement can be found in the user manual.

*Meter 81784 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.

Additional information:

• LCD display, maximum displayed result: 1999
• audible signal in circuit continuity test for resistance below 30 Ω
• automatic switch from diode test to continuity test for circuit resistance below 30 Ω (no possibility to set the meter only to diode test)
• includes measuring probes, temperature measurement probe
• construction with overload protection
• ABS housing + holster, a rubber cover protecting the meter from mechanical damage
• automatic meter shut-off
• 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.
