all have ample delays built in to allow the other link components to come online in any

sequence.

TROUBLESHOOTING THE IR LINK:

Most problems tend to occur due to the positioning of the meter relative to the base unit. There

are a few error messages that may appear on the meter’s screen:

a. Timeout: This error message occurs when too much time has passed between data sent by

the meter and the response that should have been received from the base unit. Possible

causes:

•

Meter misalignment with the Base Unit (make sure the communication windows are

facing each other, within the distance indicated).

•

No connection to the PC. The Base Unit must be connected to the PC through a USB

cable. Check connection.

b. KBD: This message occurs when the user presses a key during communications. Do not

push any key on the meter during data transfer. The meter interprets this as a request to

escape this activity and returns to the Main Menu. The base unit should return to a green

LED status in a few seconds. A message should appear on the PC screen as well, indicating

lost communications.

c. Sync: This message occurs when data framing is lost during data transmission. This would

only happen if the wireless link becomes unreliable. Ensure the meter and base unit are

aligned and restart the session.

d. Data E: This message occurs when the content of a correctly framed data packet is invalid.

Again, this is an unreliable wireless link problem.

NOTE: Individual records cannot be downloaded to the PC. The entire storage content is

delivered to the PC during a link session.

SETUP MENU:

The Setup group of features allows access to the configurable parameters of the meter. They are:

Date and Time, Power-off time, Backlight, Conversions (temperature mode and electrode type)

and Pine Mode Alarm. All can only be accessed in the Setup Menu. To get to the Setup Menu,

use the

с т keys to highlight option #3: SETUP.
