V. Others
1. Life span of LCD
The life span of LCD is considered to be about l0 years under general operating conditions, ac-
cording to the manufacturer’s catalogue. Generally, it is about 5 to 6 years in actual service.
The life span is not so much related to the number of displaying operations.
2. Printer roll sheet
(1) Supplied printer roll sheet is 28 meters long.
The roll sheet is fed at 0.125 mm/dot.
Setting the paper feed at a cycle of 1 second uses a roll of paper in 224,000 sec. (about
62.2 hours) = 28 m /0.125 mm.
(2) In case of TEXT mode
A single printing consists of the following:
1) Date (1 line),
2) Flow velocity, fl ow rate, and total (several lines),
3) Measuring conditions (1 line)
4) Paper-feed (4 mm)
A printer has a paper fed at 4 mm/line.
For example, if you select fl ow rate (m
3 /h), fl ow velocity and +total, the paper feed totals
5 lines (24 mm). If a printing cycle is assumed to set to 1 minute, a roll of paper will be
used for 1167 minutes (about 19.4 hours) = 28 meters/24 mm
