Recalling Stored Readings
To recall stored data, press the START, UP or DOWN arrow key
momentarily to "CALL" the logged data. The LCD will show a flashing
"C" (CALL) to indicate that the data shown is logged data. The data can
also be transferred to a PC using the supplied Windows
interface cable. When the datalogger is paused or when the CALL mode
is activated, select from the following activities for datalog viewing:
1. Use the arrow keys to scroll through the data on the meter's LCD
display.
2. Press and hold the UP or DOWN arrow keys to quickly scan the
logged data. The meter provides an audible tone when the first or last
reading is reached.
3. Press the UP and DOWN arrow keys at the same time momentarily to
display alternately the MINIMUM and MAXIMUM readings.
4. Press the UP or DOWN arrow key momentarily while holding the
HOLD key to search all of the trends in the recorded data list. The
LCD will indicate MIN or MAX for each trend in the list.
Datalog Item Numbers
Each logged reading has an item number (0 to n; where n is the
maximum number of records that can be stored) When the logged data
entries exceed 9999, the bargraph display indicates the most significant
digit of the item numbers > 10,000. For example, 1=10,000, 2=20,000,
etc.
Meter Memory Full
When the meter memory is full, the datalogging process ceases
automatically and the meter will enter the Auto Power OFF mode. Note
that while datalogging, the Auto Power OFF mode is disabled.
Low Battery Datalogging
If the 9V battery voltage falls critically low while the meter is datalogging,
the meter automatically ceases logging to ensure the integrity of the
data recorded.
Non-Volatile Data Storage
Data are stored in non-volatile memory shortly after each measurement
is taken to maximize data safety. However, the end-of-data information
can only be stored after a datalog event is complete. Always "StoP" the
datalogger before switching off the meter.
