3 631-X
•
In the 651, the 631-X used has been modified to allow remote control of the keypad.
A DB9 connector on the back panel allows the 651 to control the 631-X.
•
If the 631-X sample button is pressed, the reading is logged by the 651.
Do not use any other 631-X button.
•
For maintenance and calibration, the 631-X is easily removed from the 651. An
additional 631-X (P/N X631-0151/-0152) can be purchased to keep the 651
operating when you send in a 631-X for calibration.
•
To remove the 631-X:
➢
Disconn
ect the AC power for safety. If the 651 is left on, the “631 System Error”
occurs on the 651 when a sample is attempted. To clear the error, reset AC
power or wait for the 631-
X to stop sampling and select the 651’s SYSTEM /
RESET menu item.
➢
Loosen the 631-X nozzle and pull the elbow fitting out.

When replacing the 631-X, the clips that hold the 631-X in the 651 may need
adjustment. Loosen the three (3) screws for one of the clips and adjust it, so the
631-X snaps in place. If necessary, adjust the second clip as well.
•
When the 631-X is calibrated and installed back into the 651, a new VACUSHIELD
filter (P/N 800-0065) must be installed in the 651.
•
The serial number of the new 631-X must be entered into the 651 using the
SYSTEM / ID / 631 SN menu selection at the 651.
•
The 631-
X’s battery pack is internally disconnected to lower heat generation in the
651. To use the 631-X outside of the 651, re-connect the battery pack and connect
