3.4.3.2 Data Logging Screens
After pressing the START button the data that are sampled in these screens
will be stored to the built in SD memory card on the selected file until STOP is
pressed. With START the selected file will be overwritten.
3.4.4 Analog Output
The analog output provides the amplified photo-diode current or the amplified
thermal or pyroelectric sensor voltage.
The signals from the analog outputs are not wavelength and zero corrected.
The analog output voltage is range dependent and can be calculated to:
U
Analog Out
= 2V / full scale range value x measurement value
The analog output voltage can range from -0.3V to +2.3V.
3.4.5 Battery Charging
The PM100D is powered by a 1 cell LiPo
+
battery that needs to be recharged
intermittently by plugging the AC adapter or plugging the USB cable to a
computer. To fully charge the battery it takes approximately 3-4 hours. A built
in charging circuit automatically regulates and terminates the charging.
Following battery icons in the display header show the charging state from
empty to full battery
The empty battery symbol starts blinking for one minute until the unit shuts off.
When an external power supply is plugged the symbols above change se-
quent until the battery is fully charged.
