TARGAS-1 Operation Manual V. 1.02
31
If the TARGAS-1 was put into ship mode, it
will not power on until external power is applied
. To bring
the TARGAS-1 out of ship mode, first connect external power to the instrument, and then turn it on by
pressing the “ON/OFF” button. See Ship Mode Settings on page 67 for more information.
Ext Power Jack
When external power is present, the system will charge the internal battery. A power supply/charger is
supplied with the TARGAS-1 as standard. When the power supply/charger is connected to the TARGAS-
1 it will both operate the instrument continuously and recharge the internal battery when the TARGAS-1 is
powered on. If connected to the TARGAS-1 with power off it will recharge the internal battery faster.
Ext Power LED
The amber LED is illuminated whenever the power supply/charger is connected to the
EXT POWER
jack
on the back panel.
Probe Ports
There are 2 digital
PROBE PORTS
available for powering chambers and sensors.
Probe port 1 supported probes/sensors include:
•
Quantum Sensor (Apogee Instruments)
•
TRP-3 Temperature & PAR Probe
•
STP-2 Soil Temperature Probe
•
SRC-2 Soil Respiration Chamber
•
CPY-5 Canopy Assimilation Chamber
Probe Port 2 (PLC) supported probes:
•
PLC5 Leaf Cuvette
•
PLC3 Leaf Cuvette
•
TRP-3 Temperature & PAR Probe
•
SRC-2 Soil Respiration Chamber
•
CPY-5 Canopy Assimilation Chamber
Up to two different probes can be used at the same time, for example, the SRC-2 Soil Respiration
Chamber and the STP-2 Soil Temperature Probe. Note that some combinations of the above probes will
not be possible, for example, the PLC5 and the PLC3 will not work with other probes.
PLC Gas Ports
This port connection is for the PLC5 or a PLC3 leaf cuvette for measurement of leaf gas exchange. The
port provides both the supply air (reference) and the analysis (sample) air through this single gas
connection.
