The display module

The most eye-catching feature of this meter is the removable display module. Fluke has a video on its

website demonstrating its use. It can be removed from the base station by pressing two buttons on

the side. These buttons make sure the display module does not fall out accidentally. When the

display module is attached to the base station, communication is done using an infrared port: the

display module is electrically insulated from the base station. When it is removed, communication

seamlessly switches over to a 2.4 GHz RF link. This switch is really well done: there are no noticeable

delays or glitches when removing or reattaching the display module. You can also turn the meter on

when the display module is detached, although you must attach it at least once after replacing the

batteries.

Of course, this means there are always some standby circuits active in the display module: it cannot

be powered off completely, which might reduce battery life a bit. Battery life is rated 400 hours in

the manual. I wonder if this time is achieved in practice, however, partly because three of the

batteries were already empty when I received the meter.

The removable display module is especially handy when you need to measure a dangerous machine.

With this meter, you can install the base station, take the display module with you to the control

panel and turn the machine on, without the need of being near it.

One of the pictures on the Fluke website seems to suggest that the meter can also be used in climate

test chambers: the base station inside and the display module outside, so you don’t have to peek

through the possibly condensed window. Keep in mind, however, that the base station is not rated

for high humidity in combination with high temperature. This limits the suitablility for this application

somewhat.
