ELECTRICIANS DIGITAL MULTIMETER

Product catalog summary

Specifications:
The MM47 Digital Multimeter features a 3½ digit LCD with a maximum reading of 1999. It automatically indicates polarity and displays 'OL' for overrange. The device has an automatic zero function and a low battery indicator. It operates at a measurement rate of 2.5 times per second and is suitable for environments between 0°C to 50°C with less than 70% relative humidity. It can be stored at temperatures from -20°C to 60°C. The multimeter is designed for Category III installations and offers stated accuracy at 23°C ± 5°C. It is powered by a single 9-volt battery with a typical life of 200 hours.

Dimensions and Accessories:
The device measures 147mm x 70mm x 39mm and weighs approximately 340g. Accessories include ceramic fuses, fused test leads, a carry case, and optional 3-phase fused leads.

Measurement Capabilities:

DC Volts: Ranges from 200mV to 600V with a resolution of 100µV and accuracy of ± (1.2% rdg + 1 dgt).
AC Volts: Ranges from 200mV to 600V with a resolution of 1mV and varying accuracy depending on the range.
Resistance: Ranges from 200Ω to 2000MΩ with varying accuracy and overload protection up to 500V.
Continuity: Audible indication for resistance less than 100Ω with a response time of 100ms.
Diode Test: Test current of 1.0mA with an accuracy of ± (3.0% rdg + 1 dgt).
Capacitance: Ranges from 20µF to 20mF with an accuracy of ± (4.0% rdg + 10 dgts).
Frequency: Ranges from 10Hz to 40KHz with an accuracy of ± (0.5% rdg + 2 dgts).
Temperature: Ranges from -20°C to 750°C with an accuracy of ± (3.0% rdg + 2°C).
Phase Indicator: Operates within a frequency range of 45Hz to 450Hz and a voltage range of 80V to 480V.
