Features
The following sections explain the Meter features in detail. See Figure 2 and Table 2.
Remote Display
The Meter uses low-power 802.15.4 wireless technology to let the display module operate in a
different location than the Meter base. Although there is control of some Meter functions (Hold,
MIN MAX AVG, and Backlight), complete remote control of the Meter is not available through the
display module.
The wireless radio signal does not hinder Meter measurements. Usually, the radio signal is off
when the display module is docked to the Meter base. It is possible for the radio signal to be on
when the display module is docked and the Rotary Function Switch is set to OFF. To make sure
that the radio signal is off, remove the batteries from the Meter base and display module.
The display module is synchronized with a Meter base when it is docked on the Meter base and
turned on. Different display modules can be synchronized with a Meter base but, only one display
module can be synchronized to a Meter base at the same time.
