Flame signal monitoring

Note:
The flame signal strength on the flame current jack plug is only for reference and can vary between different
DBC2000 devices.
When measuring the flame signal current directly in the flame sensor wiring whilst:
1. Using a flame rod, the (multi-)meter will show the real flame current in µA.
2. Using a UV sensor (C7027, C7035 or C7044), the current in the sensor lead wires will be in the range of
20...25mA (inverted values).
