CONFIGURING THE LEVEL INDICATOR
The indicator is factory configured with colour switching thresholds, as follows:
To change this setting, proceed as follows.
To facilitate programming of the colour switching thresholds, an optional programmer is available - FPSI 1010 PROG.
SCALING
The FPSI 1010 features a voltage measurement range of 2.5Vd.c. on Vin (Vref not connected).
Two resistors Ra and Rb may be used to alter the measurement range of the indicator.
Use the following formulae to calculate values of Ra and Rb for voltage and current measurement.

Measuring input with reference to 0V.
This pin goes High when the voltage on Pin 3 is lower than the switching threshold V1.
This pin goes High when the voltage on Pin 3 is higher than the switching threshold V2.
This pin reflects the reference voltage for the module's measurement circuit.
Connect Vref to +5.0V to change the indicator's measurement range from 0 to 2.5V to 0 to 5.0V.

.
- Connect the V+ and 0V pins of
the FPSI 1010 to a 5Vd.c. supply.
- Apply the first desired voltage (V1) to Vin, then press S
- Module flashes Green to indicate that the V1 level has been stored.
- Disconnect the module. The module is now ready for use.

Step 3
- Apply the second desired voltage (V2) to Vin, then press S
- Module flashes Red to indicate that the V2 level has been stored.
- To enter solid LED mode, make sure Vin does not change, then press S
- To enter flashing LED mode, change Vin by 100mV or more, then press S
- Module flashes Red or Green to indicate that the LED mode has been stored.
