Checking Magnetron Heater Voltage; Remote Controller Setting - Furuno 1824C Installation Manual

3.2 Checking Magnetron Heater Voltage

Magnetron heater voltage is formed on the MD (1824C), PTU (1834C) or RTB
(1934C/1944C1954C) Board of the antenna unit, and preadjusted at the factory. Therefore,
no adjustment is required. However, check magnetron heater voltage for confirmation as
shown below. This procedure should only be performed by a qualified technician.
1. Open the antenna unit.
2. Turn on the power. Do not transmit the radar.
3. Connect a multimeter, set to 10VDC range, appropriate position on the MD (1824C),
PTU (1834C) or RTB (1934C/1944C1954C) Board in the antenna unit. Refer to the table
in below.
4. Confirm that the multimeter indication is within the ratings shown below.
