The YT-73091 universal clamp meter with an automatic range for most indications allows you to perform basic electrical measurements. The meter is equipped with measuring clamps that allow the measurement of alternating current in a single wire using the inductive method. The measurement takes place without the need to disconnect the circuit or disconnect it from the power source and allows the measurement of much higher currents than with conventional electrical meters.
BASIC MEASUREMENTS
alternating voltage measurement: A.C. 0-600V
DC voltage measurement: D.C. 0-600V
alternating current measurement: A.C. 0-600A
resistance measurement: 0-20MΩ
diode test: IF 1mA, UR 1.48V
continuity test: 0-120Ω
ADDITIONAL MEASUREMENTS
temperature measurement: -20 to 1000°C
MEASURING ACCURACY
Example of Accuracy Determination for AC Current Measurement. Calculations for the measurement result: 30A
the measurement accuracy of the YT-73091 meter for this range is: ±(2.5% + 5), resolution 0.1A
Measurement error calculation formula: (measurement result x 2.5%) + 5 x resolution
calculation: (30 x 2.5%) + 5 x 0.1 = 0.75 + 0.5 = 1.25A
Result taking into account the measurement error for the indication 30A = 30 ± 1.25A*
the result taking into account the measurement error for the AC voltage measurement indication: 235V = 235 ± 8.525V*
the result taking into account the measurement error for the DC voltage measurement indication: 12V = 12 ± 0.106V
The table with the resolution and accuracy for a given measurement can be found in the instruction manual.
*The YT-73091 meter does not have the true rms measurement function, therefore the above result is the real rms value of AC voltage and current only for the correct sinusoidal waveform.
BUILT-IN FUNCTIONS
AUTO - automatic adjustment of the measurement range. 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. However, in the case of a multimeter with the AUTO function, it is enough to make one measurement and the meter will automatically find the optimal range. The meter starts up in AUTO mode by default
RANGE - manual change of the measurement range. A useful function when checking many of the same components with a known value, e.g. a series of resistors. Manual range setting will reduce the time of such measurements significantly
FUNC. - changing the measurement mode, e.g. from temperature measurement from °C to °F, switching the diode test to the circuit continuity test
DATA HOLD - keeping the currently measured value on the display
MAX HOLD - keeping the maximum measurement value on the display
ADDITIONAL INFORMATION
LCD display, maximum displayed score: 1999
screen backlight
sound signal in the circuit continuity test for resistance below 50Ω
Diode and continuity tests can be switched on separately
clamps open up to 37mm and enable the measurement of a single cable with a maximum diameter of 37mm
