Box (18) - PAR-List & LED
Box (18) Lists the photon flux data of actinic light levels. See 5.6.3 for
comments on actinic light intensity.
<Sign. LED active>
The checkbox associated with <Sign. LED active> switches the LED on
the JUNIOR-PAM front panel on and off. Signal codes of the LED are
compiled in Table 5.3.

System Setting
Normal operation of the JUNIOR-PAM does not require changes of sys-
tem setting. In case system settings have been altered, default setting can
be restored using the button <Reset System Settings>.
<Ext. PAR-Sensor> and < Ext. Temp. Sensor > If a quantum or tempera-
ture sensor is connected to the JUNIOR-PAM, data input can be
adjusted via <Offset> and <Gain> settings.
<F-Offset> The number displayed corresponds to the counts of the false
signal level which is subtracted from all fluorescence signals.
False signal can originate from internal electronic "pick-up" and
