About this deal
While keeping one lead on the ground terminal, touch the second lead onto the other live terminal or wire. The AstroAI True RMS Multimeter is intended for use by experts in a commercial setting or weekend DIYers who require a little more power than their typical digital multimeter. For most home 3-wire circuits, only one wire should register a voltage of about 230V. This is the live wire.

Do not use abrasives or solvents on the meter. To clean It using a damp cloth and mild detergent only. When carrying out measurements on TV or switching p·lwer circuits always remember that there may be high amplitude voltages pulses at test points. which can damage the meter. Multimeters are available in both analogue and digital variants and can be used for everything from simple testing like battery voltage measurement to fault detection and complicated diagnostics.
Unusually for a low-cost DMM, the AstroAI machine also has several other features that are usually found exclusively on expensive high-end multimeters. These include a relatively high sampling rate of 2 times per second so that readings are likely to be accurate even if the measured signal is fluctuating. In addition, the meter also includes a ‘Relative’ button which can be used to compensate for any internal resistance from the test leads. Readings can also be captured at their maximum or minimum values using the ‘Max / Min’ button.

MULTIPURPOSE USE: Compact digital multimeter ideal for commercial and home use. Works as a voltmeter, ammeter, ohmmeter testing continuity, AC/ DC voltage, diode, transistor HFE, car battery tester.To measure the voltage of each wire, touch one of the multimeter leads on any metal object nearby. It can be the radiator or a metal pipe. That object will act as the ground reference.

It is designed to measure AC/DC Voltage Current Resistance Capacitance Frequency Temperature and comes with a K-Type Thermocouple for temperature measurements up to 1000 degrees Celsius. Features of the Product Measure the neutral wire and live wire to get the voltage of the live wire (use the sheath colours to identify which wires are neutral, live and earth). Measuring earth and live also gives you the voltage of the live wire.The MESTEK DM100 Digital Multimeter is an excellent tool for hobbyists, electricians, and household use.
