The YT-73080 universal meter with a manual range for each measurement allows you to perform basic and advanced electrical measurements. This is the basic model in our offer. Additional protection against mechanical damage is the so-called holster - a rubber casing pulled over the casing of the device.
BASIC MEASUREMENTS
Alternating voltage measurement: A.C. 0-500V
DC voltage measurement: D.C. 0-500V
DC current measurement: D.C. 0-5A
Resistance measurement: 0-2MΩ
Diode test: IF 1mA, UR 3V
Continuity test: 0-30Ω
ADDITIONAL MEASUREMENTS
hFe transistor test: 0-1000, built-in test socket
square wave generator: 5Vpp, 50Hz
MEASURING ACCURACY
Example of Accuracy Determination for AC Voltage Measurement. Calculations for the measurement result: 235V
the measurement accuracy of the YT-73080 meter for this range is: ±(2% + 10), resolution 1V
Calculation of measurement error formula: (measurement result x 2%) + 10 x resolution
calculation: (235 x 2%) + 10 x 1 = 4.7 + 10 = 14.7V
The result taking into account the measurement error for the indication 235V = 235 ± 14.7V*
the result taking into account the measurement error for the DC voltage measurement indication: 12V = 12 ± 0.146V
The table with the resolution and accuracy for a given measurement can be found in the instruction manual.
*The YT-73080 meter does not have the true rms measurement function, therefore the above result is the real effective value of the AC voltage only for the correct sinusoidal waveform.
BUILT-IN FUNCTIONS
Waveform generator - setting the knob to generate a signal will cause the meter to generate a square wave with a peak-to-peak voltage of 5Vpp and a frequency of about 50Hz. The signal can be used in audio technology, e.g. in loudspeaker diagnostics
DATA HOLD [H] - saving the currently measured value on the display
ADDITIONAL INFORMATION
LCD display, maximum displayed score: 1999
sound signal in the circuit continuity test for resistance below 30Ω
automatic switching of the diode test to the continuity test when the circuit resistance is below 30Ω (it is not possible to set the meter to diode test only)
measuring probes included
design with overload protection
housing made of ABS plastic + so-called holster, i.e. a rubber casing protecting the meter against mechanical damage
low battery indicator
power supply: 9V(6F22) battery
CAUTION
When measuring unknown values with a meter with a manual range change using the knob, measurements should be made sequentially from the largest range to the range giving the most accurate result - otherwise you risk damaging the device.更多 ALLIANCE SUPPLIES SDN BHD 相关资料
