Magnetron voltage check

[Shorty]

Have in stalled a new Furuno 1715 B&W radar. Final step is to up the mast and check magnetron voltage. Any opinions as to necessity of this. Radar appears to work fine. 1. Not over anxious to go up mast. 2. Requires removal of cover plates etc presenting great chances to loose screws etc
thx

We have a newish different model of Furuno radar and the installation instructions do not mention the need to do a final check of magnetron voltage. If it was wired correctly, supplied correct power and is working fine, I don't see the need to go up and check the voltage to it at the unit.

“... Magnetron heater voltage is formed at the MD Board of the antenna unit and is preadjusted at the factory. Therefore, no adjustment is required. However, verify the voltage as below...
... Confirm that the multimeter shows 8.0 V ±0.1 V. If it does not, adjust potentiometer VR801 on the MD Board...”

Since you're satisfied with the unit's performance, it seems like a rather unnecessary “belt & suspenders” approach, to me.

It appears to be working fine but are the returns as sharp as they might be? Is the range correct? Does the gain adjust properly? Dunno
