How often does the battery of the PIR wireless transmitter (used with the wireless rotation measurement unit and with the wireless depth measurement unit) need to be replaced?
When collecting data via the wireless transmitter the battery should be replaced daily. PDI recommends replacing the battery while installing the first pile of the day, when the auger is drilled down and the gear box is at its lowest point. Place the system in pause (the pile data will not be lost) and replace the battery. Every system has at a minimum of two batteries. When the battery is removed from the system it should be placed on a charger as soon as possible to ensure it is ready for use the following day. If you believe that there is an issue with one of the batteries, contact PDI immediately to obtain a replacement battery.
