Store, Recall, and Clear Datalogger Memory
STORE Readings
The meter can store up to 100 DO, 100 pH, 100 mV, and 100 Conductivity readings for a
total of 400 data points. To store a reading, wait until the reading stabilizes (the smiling
face icon
appears when the reading stabilizes). Press the M+/RM key momentarily to
store a reading. The M+ icon appears and the data point serial number increments.
RECALL Readings
In the measurement mode, press the M+/RM key to recall the most recently stored
reading. RM and the data point serial number for the displayed reading will appear on the
LCD. The measurement information will appear on the lower right hand side of the LCD.
Use the CAL or M+/RM buttons to scroll the remaining stored readings. Press the ENTER
key to return to the normal measurement mode.
CLEAR Readings
From the RECALL mode, press and hold the ENTER key for at least five (5) seconds. The
LCD display will show ‘CLR’ indicating that all of the stored readings have been erased.
The unit will automatically return to the normal measurement mode after approximately 2
seconds.
