SMA MY 68, Instruction Manual

Page: 2 / 26

Feature overview
MY 68 is a professional universal multimeter with a 3-digit LCD display, designed for use in production facilities, laboratories and repair
shops. The instrument comes with a handy, shock-resistant rubber case, a flip-out stand, a holder for the measuring cord and a wall hanger. The
multimeter detects the measurement range automatically and includes a graphic display. It is extremely sensitive; its best resolution is 1 µA.
Features
• measures voltage (750 V AC, 1000 V DC) • measures current (10 A AC, 10 A DC) • measures resistance (32.6 M
Ω
) • measures frequency (150
kHz) • measures capacitance (32.6 µF) • tests diodes • tests transistors with hFE/beta test • acoustic broken circuit signal • automatic display of
polarity • automatic/manual change of measurement range • indicates out-of-range input • shows battery status • measured value can be stored

MeasuriNG DC voLtaGe
1. Connect the black measuring cord to the COM socket and the red cord to the V
Ω
F socket.
2. Set the dial to the desired DCV value, and the instrument is ready to take measurements.
3. You can now connect the cords to the circuit to be measured.
4. Power up the circuit to be measured and the display will show the measured DC voltage. If you connected the measuring cords inversely, a minus sign
indicating negative polarity appears on the left.
