2.2.6 Switching on the bias voltage of the photo diode
Attention
Before switching the bias voltage on make sure that the photodiode
is poled correctly (inverse direction).
If the photodiode is forward biased with a voltage, a current will flow
through it that could damage or even destroy it.
The bias voltage is switched on by setting the parameter:
BIA1 = ON
for input 1
BIA2 = ON
for input 2
in the channel menu of the module.
2.2.7 Setting the measurement range
Each input offers 7 measurement ranges.

To set for example the measurement range to 1 mA full scale, enter
RNG1 =1.000mA
for input 1
RNG2 =1.000mA
for input 2
In the channel menu.
