The Plug-in cards are separately purchased optional cards that perform
specific functions. These cards plug into the main circuit board of the meter. The
Plug-in cards have many unique functions when used with the PAX.
Note: The PAXC and PAXR only use the setpoint option card.
CAUTION: The Plug-in card and main circuit board contain static sensitive
components. Before handling the cards, discharge static charges
from your body by touching a grounded bare metal object. Ideally,
handle the cards at a static controlled clean workstation. Also, only
handle the cards by the edges. Dirt, oil or other contaminants that
may contact the cards can adversely affect circuit operation.
To Install:
1. With the case open, locate the Plug-in card connector for the card type to be
installed. The types are keyed by position with different main circuit board
connector locations. When installing the card, hold the meter by the rear
terminals and not by the front display board.*
2. Install the Plug-in card by aligning the card terminals with the slot bay in the
rear cover. Be sure the connector is fully engaged and the tab on the Plug-in
card rests in the alignment slot on the display board.
3. Slide the meter base back into the case. Be sure the rear cover latches fully
into the case.
4. Apply the Plug-in card label to the bottom side of the meter in the designated
area. Do Not Cover the vents on the top surface of the meter. The surface of
the case must be clean for the label to adhere properly.
