A high input impedance does not introduce errors when measuring values and indicates a high accuracy of the device. The device uses an ADC with measurement of values by the method of double integration. The selection of the limits of measurement of quantities is made automatically, except for the measurement of the current strength. In this case, the rotary switch selects the measurement limit, and the button selects the variable or constant values of the measured value.
A good protection circuit for the device - when "measuring the resistance of the socket" (that is, if a high voltage accidentally hits the probes of the device with the selected resistance measurement), the fuse blows, the device does not fail.
There is no automatic power off, which allows using the device for professional purposes without waiting for it to "fall asleep" at the most inopportune moment.
The multimeter allows you to measure the following parameters:
- direct and alternating current (up to 20 A)
- constant and alternating voltage
- resistance
- capacitance of capacitors
- gain of bipolar transistors
- the frequency of the sinusoidal signal
Also available:
-
audible chain ringing,
-
pn junction testing (diode test),
-
measurement of the gain of transistors.
Convenience in work will be provided by the following functions:
-
overload protection
-
data hold (HOLD button)
-
low battery indication (7.5 V).
-
protective casing - "galosh" made of soft polymer, included in the delivery set of the Mastech MY68 multimeter, will keep the device from damage if dropped or hit, and will also provide a convenient angle of inclination using a stop on the back of the casing
