- Page 8 When running the FT420 with a magmeter (which requires power), the FT420 must be connected to two power supplies, one for the magmeter and one for the 4-20 mA loop. You may either use a dual power supply (available from Seametrics as the PC42), or two single power supplies (one of which may be the 4-20 mA loop itself).
