Do not measure the measured resistance

Do not introduce a voltage higher than 6V at the measurement input! ! Doing so can damage the IC. For example, when measuring large inductance transformer and motor , a relatively high induced voltage may be generated during measurement, and energy discharge should be performed. The (coil) can be tested with a diode on both sides.

can be use on

Measuring tiny current sampling s

Motor coil resistance

Transformer coil resistance

Mos tube on resistance

Switch contact contact resistance

USB data line resistance, you can judge the merits of the data line.

Calibration method:

Take a 1 ohm , first measure the true value with a higher than the accuracy of the meter head, then connect the to the meter to measure, adjust the 3296 multi-turn potentiometer of the meter head, so that the display value of the meter head and The value of the resistance measured by the high-precision meter can be within ±1 words (for example, the high-resistance digital bridge measures the resistance of 10 ohms to 10.01 ohms, and the resistance is connected to the meter to measure the value from 10.00 to 10.02. ), it is best to use a four-wire clamp for calibration.

Instructions:

1. Pre the wire terminal as shown below, from left to right, power supply is positive (red), power supply negative (black), I-(white), Vin- (yellow), I+ (green), Vin+ (blue) Color) I+, I- is the current pin, Vin+, Vin- is the measuring pin. When using the four-wire measurement, I- and Vin- are a cl, I+ and Vin+ are a cl. No Kein cl can be used to turn white + yellow and blue. + Green is screwed together and can be measured, but the measurement error will increase.
