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 software and
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. This LCD will indicate MIN or MAX for each
trend in the list.
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 safely. However, the end-of-data information can only be stored after a
datalogging event is complete. Always ‘StoP’ the datalogger before switching off the meter.
