Mastech MY70 Manual Ranging Digital Multimeter

Description

The MASTECH MY70 is a manual ranging digital multimeter that measures AC/DC voltage, AC/DC current, and resistance. Unlike an auto-ranging meter that automatically selects the correct range, a manual ranging meter requires the user to select the appropriate range with a rotary dial. This makes the MY70 a simple, reliable tool suited for basic testing.

Key Features

• Manual ranging: You must manually set the range before making a measurement to prevent an "OL" (overload) reading.
• 2000-count display: The LCD can display up to 1,999 digits, which is standard for a manual ranging meter.
• Data hold: This feature allows you to freeze the reading on the screen, which is useful for recording measurements.
• Continuity buzzer: The meter produces an audible beep when it detects a continuous connection with less than 50Ω of resistance.
• Diode and transistor testing: The MY70 includes functions to test the forward voltage drop of diodes and the hFE (DC current gain) of transistors.
• Auto power-off: The meter shuts down automatically after a period of inactivity to save battery life.
• Safety rating: It has a CAT III 600V safety rating for use in industrial and residential electrical environments.
