TO STOP LOGGING
In order to stop the recording mode, press
ALT and LOG keys (press ON/OFF first, if
meter is in sleep mode).
A last printout reporting the number of
logged samples (e.g. S.00009) will be pro-
duced if printer is enabled.
Notes:
• It is recommended to use the adapter during logging in printing
mode, especially when many printouts are going to be taken.
• Before proceeding with logging with printing, make sure there is
enough paper for your measurements. When the paper is finished
the meter will not advise the operator and the printouts could be
lost. If this happens, data will continue to be stored in memory,
and it is always possible to print the data at a later time
through setup code 00.
• It is possible to insert a new paper roll during logging session (see
page 29)
• Once in the logging mode, the interval cannot be changed. Exit
the logging mode first (pressing the ALT and LOG keys) to set a
new interval.
• If the LOG key is pressed while in logging with printing mode, a
printout is produced without affecting the running sample num-
ber and the value is stored in Log on demand area.
LOW BATTERY CONDITION
Printout is automatically disabled when battery charge weakens. The
last message "Stop log" will be printed and
data will continue to be stored in memory
with the LOG and LOBAT symbols blinking
on LCD. If the user attempts to enable the
printer while in low battery condition the
message "bAtt" will appear for a few sec-
onds on the LCD.
Note: When an external adapter or new batteries are connected, the
printing must be manually enabled in order to return to
logging with printing mode.
LOG ON DEMAND
In measuring or Timed log mode, press LOG to
store the current reading. The LCD will display
Two different modes to print / log data are available:
1. Timed logging; samples are stored and printed (if print function is
active) at fixed time intervals. Data are stored in the lots 01 to 16.
2. Log on demand; samples are stored and printed (if print
function is active) when the LOG key is pressed. Data are stored
in the lot 00. It's possible to perform the Log on demand either
in normal mode or in Timed logging mode.
It is possible to switch from logging without printing to logging with
printing in two ways:
• set the function code 02 to "On" to enable printing, to "Off" to
disable printing
• press ALT and PAPER to toggle between printer enabled and
printer disabled while in Timed logging.
TIMED LOGGING MODE
To start Timed logging, press ALT and LOG.
The lot number will be displayed for a few
seconds then the LOG symbol will appear on
LCD and if printer is enabled a first set of
data will be printed. The "LOG" symbol will
be fixed if printer is enabled and will blink if
printer is disabled.
The printout provides the following information:
a - Lot number
b - Logging interval
c - Date (only for the first printed
sample of the lot or of the day)
d - Sample number
e - Time
f - Readings.
To print the mV reading instead of pH, press ALT and LOG after
entering the mV range (mV reading available in HI98240 only).
If no keys are pressed, the meter enters standby mode to prolong the
battery life and only the "LOG" indication will be visible on LCD. While
logging, during the sleep mode, the last logged reading will appear
briefly on the LCD. To reactivate the LCD press ON/OFF.
