RS PRO IDM20 Pocket Digital Multimeter

The RS PRO IDM20 digital multimeter (DMM) is a handheld tool which can measure capacitance, voltage, electrical current and resistance with diode and continuity check. This meter has an LCD display where the measurement readouts can be viewed. There is also a “hold” function available in the compact design making it very user-friendly. The multimeter is also CAT IV rated for 600V and CAT III rated for 1000V.

With built-in non-contact AC voltage detection, this battery-powered device is great for continuity and portability. A robust, double-moulded, plastic housing provides ultimate protection from harsh environments. Included with the meter itself are integral test leads, 2 X AAA batteries and a user manual.

The IDM20 is RS Approved, meaning not only is it great value for money, but you can rely on its quality.

Features and Benefits:

• Integrated flashlight
• Compact and handheld - pocket size
• Digital 3-3/4 digit 4000 count LCD display
• 3-year warranty
• 104 x 55 x 32.5 mm dimension

What does it measure?
DC/AC Voltages
AC/DC Current
Resistance and continuity checking
Diode - open circuit voltage

What does it include?
Pair of Integral Test Leads
Battery (Installed) - Two 1.5V AAA batteries
User Manual

Typical Applications:
A digital multimeter (DMM) is a handy test tool that measures electrical values such as voltage, current, and resistance. A DMM is used by technicians in the following areas:
Electrical and electronic industries

Safety guidelines
When using any electrical test equipment it is advised that you refer to the user’s manual for proper working operating procedures and safety precautions in order to avoid potential safety hazards.

What is the difference between an analogue and a digital multimeter?
The main difference is the display. A digital multimeter will show the results as numbers on a screen (usually a LED or LCD screen) whereas the analogue version has a needle to show the value.
