7.2.2 V
After TEG has Stabilized
set
Once the TEG has been running for some time, typically more than an hour, the power
unit will be up to operating temperature.
Follow these steps to check V
a)
Consult the data plate inside TEG door for the reference V
mine the required V
or 7.1.2.
b)
Move the jumper clip on the terminal block TB-1 to the SETUP position, i.e.
between terminals 2 and 3. This connects the TEG to an internal load required
for V
set
c)
Connect a voltmeter between terminals 2 (+) and 4 (-). The measured V
should match the required V
Caution:
d)
Pause approximately 10-45 minutes and when the measured voltage is stable
compare it to required V

Note: Pausing is necessary to allow the TEG voltage to stabilize to the new load con-
ditions. (Changing from customer load to the on-board 1 ohm resistor).
