digital tester

The multimeter 81784, with a manual range for each measurement, allows you to make basic and advanced electrical measurements. built-in additional measuring sockets facilitate the measurement of, among other things: capacitors and transistors. additional protection against mechanical damage is the so-called holster - i.e. a rubber casing stretched over the device body.
basic measurements:

• AC voltage measurement: ac 0-600 v
• DC voltage measurement: dc 0-600 v
• alternating current measurement: ac 0-10 a
• direct current measurement: dc 0-10 a
• resistance measurement: 0-200 mω
• diode test: i f 1 ma, u r 2.8 v
• circuit continuity test: 0-30 ω

additional dimensions:

• capacitor capacity measurement: 0-20 μf
• frequency measurement: 0-20khz
• temperature measurement: -40 to 400 °c
• hfe transistor test: 0-1000, built-in measuring socket

measurement accuracy:
an example of determining the accuracy of an AC voltage measurement. calculations for the measurement result: 235 v

• The measurement accuracy of 81784 meters in this range is: ±(1.2% + 5), resolution 1 v
• formula for calculating measurement error: (measurement result x 1.2%) + 5 x resolution
• calculation: (235 x 1.2%) + 5 x 1 = 2.82 + 5 = 7.82 v

reading 235 v = 235 ± 7.82 v* the result taking into account the measurement error

• the result, taking into account the measurement error, to show the DC voltage measurement: 12 v = 12 ± 0.08 v
• the result, taking into account the measurement error, to show the AC measurement: 8 a = 8 ± 0.26 a*

For a table with resolution and accuracy of a given measurement, please refer to the user manual.
*the 81784 meter does not have a true rms measurement function, so the above result is the true rms value of the AC voltage only for the correct sine wave form.
additional information:

• LCD screen, maximum displayed result: 1999
• beep in continuity test for resistance below 30 ω
• automatic switching of the diode test to the continuity test if the circuit resistance is less than 30 ω (it is not possible to set the meter only for the diode test)
• the set includes measuring sensors, a probe for measuring temperature
• design with overload protection
• abs plastic case + so-called holster, i.e. a rubber case that protects the meter from mechanical damage
• automatic shutdown of the meter
• low battery indicator
• power source: 9v battery (6f22)
