ADM-880C 07/20/0929
The readings will remain stored in the meter memory until the memory is cleared by pressing the ALT / STORE / READ
key sequence.
5.10.4 IMPORTING SAVED DATA INTO A SPREADSHEET
The following example is for Microsoft Excel. Start Excel, and select File > Open. Navigate to the directory where the data
file was saved. In the “Files of Type” box at the bottom of the Windows file dialogue box, select “Text Files” or “All Files”.
Select the file where the data was saved (it will have a *.csv extension). The data will be imported into the Excel
spreadsheet. It may be necessary to adjust the column widths and cell justification settings to improve readability. The
spreadsheet may be saved and recalled as an Excel file with a *.xls extension.
An example of ADM-880C AirData Multimeter readings imported into an Excel spreadsheet is shown on the following page.
5.11 BATTERY DISPLAY AND BATTERY LIFE
The AA NICAD batteries supplied with the meter are capable of supplying power for more than 3000 readings after one 10-
hour charge. When the batteries are nearing the end of their useful charge, the meter will begin displaying [LOCHARGE].
If the meter is in the MANUAL or automatic reading mode, the symbol of a discharged battery cell will appear in the third
block of the displayed reading. The operator should plan to complete the reading session when [LOCHARGE] is displayed.
If the meter is being used with the backlight turned off, the user will have approximately 20 minutes of runtime before the
meter displays [RECHARGE / SHUT DOWN] and turns itself off. The time period will vary depending on prior use. The
batteries must be recharged prior to further use.
If the meter has been being used with the display backlight turned on, the user will have approximately five to 20 minutes
of runtime before the meter displays [RECHARGE / SHUT DOWN] and turns itself off. The time period will vary depending
on prior use. The meter may be turned back on without the backlight for use until [LOCHARGE] is displayed again. The
user will have five to ten minutes of additional runtime before the meter displays [RECHARGE / SHUT DOWN] and turns
itself off. The batteries must be recharged prior to further use. See Section 2.0 SPECIFICATIONS and APPENDIX C for
more information about the batteries and the battery charger.
The battery status can always be viewed by pressing ALT / ALT. The first display indicates the approximate remaining
battery life: [BATTFULL], [BATT 2/3], [BATT 1/3] or [LOCHARGE]. A battery charge level displayed when the meter is first
turned on, may not be representative of the true level of battery charge. Wait five or ten minutes after turning the meter
on to view the charge level.
5.12 RESET SWITCH
If the meter is dropped or affected by static electricity, it may become unresponsive. Press the red reset pin on the back
of the meter for one second. A reset causes the loss of all readings stored in memory since the meter was last turned on.
However, readings in memory when the meter is turned off are saved such that a subsequent reset will not affect them.
