Digital Clamp Meter YT-73091 YATO

The YATO YT-73091 Digital Clamp Meter is a versatile tool designed to perform basic electrical measurements with ease. Equipped with measuring clamps, it enables users to measure AC current in a single wire inductively without disconnecting the circuit or power source, allowing for higher current measurements compared to traditional meters.

Basic measurements include:

• AC voltage measurement: 0-600 V a.c.
• DC voltage measurement: 0-600 V d.c.
• AC current measurement: 0-600 A
• Resistance measurement: 0-200 MΩ
• Diode test: IF 1mA, UR 1.48 V
• Circuit continuity test: 0-120 Ω

Additional measurements include:

• Temperature measurement: -20 to 1000 °C

Measurement accuracies:

For example, when measuring AC current, if the measurement result is 30 A, the accuracy of the YT-73091 in this range is ±(2.5% + 5), with a resolution of 0.1 A. The calculation for measurement error is as follows:

• Measurement error calculation: (measurement result x 2.5%) + 5 x resolution
• For 30 A: (30 x 2.5%) + 5 x 0.1 = 0.75 + 0.5 = 1.25 A

This means that the measurement result of 30 A would be 30 ± 1.25 A.

• For AC voltage measurement of 235 V, the result would be 235 ± 8.525 V.

For DC voltage measurement of 12 V, the result would be 12 ± 0.106 V.

Refer to the user's manual for detailed tables of resolution and accuracy for each measurement.

Note: The YT-73091 does not feature true RMS measurement, so results represent the real RMS values of AC voltage and current for normal sinusoidal waveforms only.

Built-in functions:

• AUTO: Automatically adjusts the measurement range. With manual range adjustment, measurements can start from the largest range to ensure device safety. In AUTO mode, the meter automatically finds the optimal range.
• RANGE: Manual adjustment of the measurement range, helpful for checking multiple components with known values.
• FUNC: Switch measurement modes (e.g., from Celsius to Fahrenheit for temperature measurements).
• DATA HOLD: Retains the currently measured value on the display.
• MAX HOLD: Retains the maximum measurement value displayed.

Additional information:

• LCD display with a maximum reading of 1999.
• Screen backlighting.
• Audible signal for circuit continuity tests for resistance below 50 Ω.
• Separate enabling of diode and continuity tests.
• Clamps open up to 37 mm, allowing for measurement of single wires with a maximum diameter of 37 mm.
• Includes measuring probes and a carrying case.
• Design includes overload protection.
• Automatic meter shutdown feature.
• Low battery indicator.
• Power supply: two 1.5 V (AAA) batteries.

Warning: Measuring current with clamp meters should only be done on a single conductor. Clamping on multi-conductor cables without isolating a single conductor will yield incorrect or zero results.
