أفوميتر YT-73080
Universal meter YT-73080 with manual range for each measurement allows you to make basic and advanced electrical measurements. This is the basic model in our offer. Additional protection against mechanical damage is the so-called holster - that is, a rubber case stretched over the housing of the device.
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 MΩ
- diode test: IF 1 mA, UR 3 V
- circuit continuity test: 0-30 Ω
Additional measurements:
- hFe transistor test: 0-1000, built-in measuring socket
- rectangular waveform generator: 5 Vpp, 50 Hz
Measurement accuracies:
Example of determining accuracy for AC voltage measurement. Calculations for the measurement result: 235 V
- measurement accuracy of YT-73080 meter for this range is: ±(2% + 10), resolution of 1 V
- calculation of measurement error formula: (measurement result x 2%) + 10 x resolution
- calculation: (235 x 2%) + 10 x 1 = 4.7 + 10 = 14.7 V
Result including measurement error for 235 V indication = 235 ± 14.7 V*
- Result including measurement error for DC voltage measurement indication: 12 V = 12 ± 0.146 V
For a table with resolution and accuracy for a given measurement, please refer to the instruction manual.
*The YT-73080 meter does not have a true rms measurement function, so the above result is the real rms value of AC voltage only for a normal sine waveform.
Built-in functions:
- Waveform generator - setting the knob to generate a signal will cause the meter to generate a rectangular waveform with a peak-to-peak voltage of 5 Vpp with a frequency of about 50 Hz. The signal can be used in audio technology such as speaker diagnostics
- DATA HOLD [H] - retaining 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 at circuit resistance below 30 Ω (it is not possible to set the meter only for diode test)
- measuring probes included
- construction with overload protection
- ABS plastic housing + so-called holster, i.e. rubber casing to protect the meter from mechanical damage
- low battery indicator
- power supply: 9 V (6F22) battery
Attention!
When measuring unknown values using a meter with a manual range change using the dial, make measurements sequentially from the largest range up to the range giving the most accurate result - otherwise you risk damaging the device.
