HMP230 SERIES

M210225en-B Appendix 9: Re-gaining

147

suitable in an ambient with a gas flow rate of 2 m/s or more around the sensor

head. Furthermore, if the settling time is very long and the temperature

difference small (close to zero) and the ambient temperature changes during

re-gaining, the sensor may not reach the temperature difference within the

settling time and the transmitter will remain inactive for a long period of time.

3. LED COMMANDS

Re-gaining can be started manually using the LED command ll¡¡ (l = lit,

¡ = dark). Use the up and down press switches (marked with arrows in the

printed board) to find the command code and acknowledge it with the ENT

switch. The re-gaining parameters stored in the transmitter memory are used.

When re-gaining is over the LEDs are dark again.
