Setting the Gain
(Units with a Serial Number earlier than 75100)
Prior to November 2020 (Serial No: 75100) a Hyperion was set to the default range, for its specific
analyte, before leaving Valeport. After November 2020 MK2 PCBs were installed in all Hyperions
and that removed the need to set the gain. If you bought your Hyperion after November 2020 you
can ignore this section.
The default range for any analyte will be its low range and, therefore, the instrument will be set to
maximum sensitively and gain. This will allow the measurement of low concentrations of the
analyte. Within this range there will be a linear response over 3 orders of magnitude
For Example:
In the case of Chlorophyll, the default range is: 0.025 µg/l (MDL) to 25.0 µg/l (FSD)
In the case of Fluorescein, the default range is: 0.01 ppb (MDL) to 25 ppb (FSD)
If high fluorophore concentrations are encountered, the range should be set to the non-default
setting to allow a linear response over a far wider range.
The gain can be set as part of the set-up wizard in DataLog x2:
For dye tracing applications, we recommend using the
Hyperion at the default range, that is, high
gain\sensitivity to reduce the quantity of dye required
and, therefore, the visibility / load on the environment
and or disposal costs.
This setting has no effect on Hyperion Fluorometers with
MK2 PCBs. All Hyperions supplied after November
2020 (Serial No: 75100) have MK2 PCBs. If you get an
error concerning #400 commands change the
instrument to:
Hyperion X - .SN > 75100 Nov 2020
in the drop down menu.
If you have a MK2 PCB and attempt to set the gain using
DataLog x2 the error will look like this:
Do not worry
