11.4 Printer Carriage Adjustment (Dot Model)
It is recommended to adjust the position of the carriage once a year.
To adjust the carriage, proceed as follows:
• Allow a warm-up time for the recorder of at least 30 minutes. Check that the ambient
temperature and humidity are within Normal Operating Conditions (see chapter 10
‘General Specifications’).
•Enter the SET UP Mode by turning ‘ON’ the power while pressing and holding the
ENT-key until the SET UP display appears.
•Press the ENT-key until the display ‘SETUP=P_ADJ’ appears. Press the ENT-key.
•You can now select to adjust the ZERO position of the carriage (left side of the chart),
HYS position of the carriage (middle of the chart) or the FULL position of the carriage
(right side of the chart). It is recommended to adjust the HYS position first, and ZERO
position before the FULL position.
Select HYS and press the ENT-key.
The carriage should print a straight line, but might print as follows:
Figure a Figure b
If the line looks like the one shown in figure a, adjust the value on the display to a
bigger value. Then press the ENT-key.
If the line looks like the one shown in figure b, adjust the value on the display to a
smaller value. Then press the ENT-key.
Continue this procedure until the carriage prints a straight line. Changing the value 1
digit will result in a carriage movement of approximately 0.1mm.
• Then select ZERO. The carriage will print a line on the left side of the chart. This line
should be the ‘0’ position. If the line is printed before the ‘0’ position (which can be
seen from the grid on the chart), adjust this by entering a bigger value.
After adjusting, press the ENT-key.
•Then select FULL. The carriage will print a line on the right side of the chart.
This line should be the ‘100’ position. If the line is printed before the ‘100’ position
(which can be seen from the grid on the chart), adjust this by entering a bigger value.
After adjusting, press the ENT-key.
• This adjustment has been completed, but before leaving the SET UP Mode, you have to
store these settings. Press the ESC-key to return to the ‘SETUP=P_ADJ’ display and
then select the ‘SETUP=END’ display.
Press the ENT-key. Select ‘END=STORE’ to keep your new settings or
‘END=ABORT’ and press the ENT-key. After a few seconds, the Operation Mode will
appear.
