Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Arc voltage | 9 V | — | — | — | — |
| Ignition voltage | 22 V | — | — | — | — |
Application Notes
In order to obtain the ignition voltage of 22 V, an auxiliary D.C. supply unit delivering min. 40 V, 10 mA power should be connected via a current-limiting resistor to the auxiliary ignition electrode ah (+) and to the cathode (-).
