Support - Changing the Battery or Batteries
Electrocorders use alkaline primary cells, generally IEC size code ‘6LR61’ (9V Alkaline) also known as ‘E’ or IEC size code ‘LR14’ (1.5V Alkaline) also known as ‘C’. Please refer to your user instructions for exact sizes to use in your logger. For logger that have no retaining mechanism other than the battery holder itself, we recommend the use of cable-ties (tie-wraps) to hold the batteries in place.
Insert the end of the driver between the cover and the side of the case, then gently twist, the cover will pop up.
Using a small posi-driv remove the four screws, when all four are fully removed open the case carefully. Note in some IP65 sealed models of the EC-6AV and EC-7VAR you may have to loosen the sealing nut on the cable gland for the voltage leads (NOT those on the current sensors), and allow the four voltage input cables to move freely.
