CHAPTER 8 COMPONENTS OF THE MINI-PAM
- Remote control push button
Pressing the 'remote' control push button on the handle of the
Leaf-Clip Holder 2030-B is equivalent to operation of START on the
MINI-PAM keyboard. In practice, this offers the advantage, that the
experimenter can use both hands for positioning the leaf within the
holder and at the same time trigger a recording by remote control. In
this way, sampling is considerably facilitated, which is particularly
helpful when many recordings are averaged to increase the accuracy
of determinations.
Approx. 0.2 seconds elapse between pushing the remote control
button and triggering of the saturation pulse. The actual start of the
measurement is announced by a beep-sound. From that moment
onward the leaf clip should be held steady for approx. one second.
- Tripod mounting thread
Mounting the Leaf-Clip Holder 2030-B on a tripod (e. g.
Compact Tripod ST-2101A) facilitates long term recordings with the
same plant. Such recordings can be automated by using the Clock-
function.
- Holes for mounting External Halogen Lamp 2050-HB
Two holes are provided in the front bottom part of the holder for
mounting the optional External Halogen Lamp 2050-HB (see 8.5).
This lamp allows long periods of illumination with strong light, as e.
g. required for photoinhibitory treatment. It is not recommended to
use the internal halogen lamp for this purpose, as this would lead to
excessive internal heating and rapid depletion of battery power.
