good video my estimate, my query is, I have a 415 that I cannot calibrate, the HC reaches 38% LEL and fails. what can i do ?? I would appreciate your comments. I AM using for calibration 50%lel gas
Hi Juan, depending on the age of the unit the sensor may need replacing as part of the regular service and maintenance. Sensors do degrade over time and usually show this as a reduced response to the target gas.
@@ControlEquipment ok, well understood. Within the equipment there are two preset, gain 1 and 2, how can I use them to be able to calibrate the HC part? Thanks
