Versatile Electrical Tester

The AstroAI ASIDM130B is a 4000 counts digital multimeter designed for automotive and general electrical troubleshooting. It measures AC and DC voltage, AC and DC current, resistance, continuity, capacitance, diodes and batteries. Auto and manual range selection gives flexibility for both quick checks and detailed diagnostics. The package includes test leads, alligator clips and a user manual.

Build Integration Needs

The meter operates on three AAA batteries and functions within 32°F to 104°F at less than 80% relative humidity. Its 145×73×34 mm footprint and 185 g weight allow it to sit on a bench kickstand or be carried in a tool bag. CAT III 600 V rating and dual ceramic fuses (F500mA/600V and F10A/600V) protect the instrument and free the user from external protection modules for rated environments.

Sustained Load Behaviour

Sampling runs at two times per second, providing steady updates during extended monitoring sessions. Overload protection on all ranges and a thermistor circuit guard against damage during prolonged high-current or high-voltage measurements. The backlight LCD and data hold retain readability when ambient light changes or when hands are occupied. Storage tolerance spans 14°F to 122°F at less than 85% RH.

Questions about this item

What is the maximum voltage the CAT III 600V rating allows for continuous measurement?

The meter is rated for CAT III 600V, meaning it can safely measure up to 600 volts in building installations.

How much heat does the multimeter generate during extended use?

The device is battery powered with low current draw and has no active cooling, so it produces negligible heat during all day operation.

Which batteries must be installed before the multimeter will turn on?

Three AAA 1.5V batteries are required and are not included in the package.
