Fluke’s 233 DMM is said to be the industry’s first digital multimeter (DMM) with a detachable wireless display. The unit uses a 2,4 GHz ISM band wireless transmitter to immediately send measurements to the detached display, giving users flexibility in unusual test situations. By simply sliding the wireless display out of the meter body, the user can place the display where it is most easily seen – up to 10 metres from the point of measurement – while putting the meter in the best position to take measurements.
Designed for both convenience and safety, the Fluke 233 makes it easier to take measurements in hard-to-reach places, or make measurements in machines or panels that are physically separated from a limit or isolator switch. It is ideal in areas where the operator cannot be close to the active measurement point, like clean rooms or hazardous areas. Making measurements without holding the meter can help users improve their visual focus on their test probes and work more safely.
The low-power wireless signal that transmits measurement data is resistant to electromagnetic interference. The radio transmitter automatically turns on when the display is removed from the meter and off when the display is reattached. The removable display is magnetic and has a flat bottom, so it can be conveniently mounted or placed on a flat surface where it can easily be seen. When the display is attached, the Fluke 233 operates as a conventional multimeter.
The DMM will measure up to 1000 V a.c. and d.c. and up to 10 A. It features a 10 000 μF capacitance range, measures frequencies to 50 kHz and captures min/max and average readings automatically. It features a 6000-count display and includes a built-in thermometer that enables users to take temperature readings without carrying a separate instrument. The meter body is powered by three AA batteries; the display has two AA batteries. Average battery life is 400 hours, maximised by an auto-off feature. The Fluke 233 is safety rated for use in CAT IV 600 V/CAT III 1000 V working environments.
