Magnetron heater voltage

Magnetron heater voltage is formed at the MD Board of the antenna unit and preadjusted at the factory for use with any length of signal cable. Therefore no adjustment is required. However, verify heater voltage by following the procedure below.

1.Turn on the radar (if it is not already on) and set it in stand-by.

2.Open the antenna housing (radome) cover. Connect a multitester, set to 10 V DC range.
