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.
Note: In timed logging mode, channels with no probe connected are
not logged nor printed. If all the channels are disconnected,
the message "no connected probe" will scroll across the LCD.
Note: cold junction temperature is not logged nor printed.
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 ("----" means out of range).
Note: 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

THERMOCOUPLE CALIBRATION
1. With a mV simulator, input 0.000 mV at channel #1 of the meter.
2. Ensure the meter is not displaying the cold junction temperature
and press ALT, CFM and PAPER simultaneously while the meter is
not printing nor logging to enter calibration mode.
3. User is prompted to enter password if it has been set to a value
different from 0000, otherwise skip to step 6.
4. Enter the password using the arrow keys.
5. Press ALT and CFM to confirm or CH/TIME or TEMP/TIME to exit.
6. If password is correct or not set, the meter
will display "0°C" on the upper LCD and
"C 0" on its lower part; if wrong, it will
return to measurement mode without any
message.
7. When the "S" symbol blinks in the lower
LCD, the reading is stable and calibration
can be confirmed pressing ALT and CFM.
8. The LCD will display CALC for a few seconds.
9. The second calibration point "1000°C"
will be displayed on the upper LCD and
"C 0" on its lower part.
10.Input 41.269 mV at channel #1 of the meter.
11.When the "S" symbol blinks in the lower
LCD, the reading is stable and calibration
can be confirmed pressing ALT and CFM.
12."CALC" is displayed on the upper LCD for a few seconds and then
the meter returns to normal operational mode.
Note: Even though only channel #1 is used during calibration, all
the channels and all the thermocouple types are calibrated.
Note: If a wrong input is connected or channel #1 is left open, when
confirming the calibration point the LCD will display "Err".
Note: To escape before ending the calibration procedure press CH/TIME
or TEMP/TIME.
Note: When connecting a mV simulator to the meter use two wires of the
same material of the simulator terminals to avoid undesired ther-
mocouple junctions that could alter the mV input of the meter.
Note: Avoid touching the meter connectors if possible and wait about 15
minutes for temperature stabilization after connections before pro-
ceeding with the calibration steps.
