WORKING SAMPLE
(HI 955301 and HI 955302 only)
The following step by step description refers
to a typical monitoring situation, after insert-
ing the batteries and setting date and time.
Suppose that the meter is used to monitor
and store every 2 minutes. The meter will log
10 samples but print only 3, display the data
contained in sample #1 and print samples 5
through 10.
Example:
Step 1 - Setting a 2-minute interval
Press ALT and TIME keys twice. The time
will be displayed together with the blinking
printing/logging interval.
Press the UP or DOWN key until a blinking
"2" appears.
Press ALT and TIME keys to exit. The dis-
play will now show the current time together
with the selected interval of 2 minutes.
Step 2 - Entering the log mode
Press ALT and LOG keys. "L 01" will appear
on the primary display.

Press the DOWN key to revert back to sam-
pling time and move back through samples.
To exit the recall mode, press LOG.
Note: This mode will not alter data into
memory
TO PRINT STORED DATA
Once a log number is se-
lected by using the ALT and
DOWN keys, all or part of
that log section can be printed
by pressing ALT and PRINT
simultaneously. The printer
will print the logged section,
beginning with the selected
sample number and without
altering the memory content.
Note: It is always possible
to print only the dis-
played sample by
pressing PRINT.
Note: Before proceeding with printing, make
sure there is enough paper for the data
to be printed. When the paper is fin-
ished the meter will not advise the
operator and printouts could be lost.
If this happens, stop
the printer by press-
ing ALT and PAPER
simultaneously. Data
will be kept in memory.
Insert a new paper roll (see "Printer
Maintenance" section for details) and
repeat the above instruction starting
from the last printed sample number.
