Designs A and B: Connect measuring instrument for ionisation current measurement
Use pointer amperemeter with a measuring range of 0-300 mV. 10 mV correspond to 1A.
Fig. 5-19 Connect amperemeter to measuring terminals
Procedure:
1 Deactivate flame monitor.
2 Connect measuring instrument to the flame monitor.
3 Activate flame monitor.
Designs C: Connect measuring instrument for ionisation current measurement
Procedure:
1 Deactivate external flame monitor.
2 Connect measuring instrument to the external flame monitor.
3 Activate external flame monitor.
Perform measurement:
Flame quality and flame stability are set by regulating the gas and air pressure.
An even and stable flame signal is always preferable to a high, but fluctuating flame signal..
Procedure:
1 Ignite the flame.
2 Read the measured values.
3 Set the flame to maximum flame quality while observing the measured value.
– Even needle deflection = high stability
– Uneven needle deflection = low stability
Stop the measurement
Procedure:
1 Deactivate the flame monitor
2 Disconnect measuring instrument.
3 Screw off pressure gauges.
4 Screw grub screws into the measurement sockets up to the limit stop.
5 For versions A and B: Close the protective caps of the measuring sockets.
