JRC JMR-5410-6XH - Testing the Brightness of LED [Light Test]; Checking the Magnetron Current Level of the Radar Antenna [Magnetron Curr.]; Checking the Memory [Memory Check]

Section 15 Maintenance & Inspection 15-14
15.4.4 Testing the brightness of LED [Light Test]
Test the brightness of the LED of the operation unit.
[Operation procedure]
Open the Light Test screen by performing the following menu operations.
[Menu] button → Maintenance → Diagnosis → Light Test
1 Click on the [Light Test Start] button.
A LED brightness test starts. All the available brightness level can be tested by increasing the
level from 0.
15.4.5 Checking the magnetron current level of the radar
antenna [Magnetron Curr.]
This function is used to check the magnetron current level of the radar.
This function is displayed only when the magnetron radar antenna is connected.
[Operation procedure]
Open the magnetron current test screen by performing the following menu operations.
[Menu] button → Maintenance → Diagnosis → Magnetron Curr.
The magnetron current level of the radar antenna is displayed.
The current level is normal if it is within the following scope under the 48 NM range.
10 kW transmitter: Scale 4 to 7
25/30 kW transmitter: Scale 6 to 9
Memo
In the sector blank area, the display of the magnetron current becomes unstable.
Check that there are no fluctuations (drift) of 2 scales or more while sector blank is not set. For the
details of sector blank setting, refer to “14.2.4 Setting Sector Blank”.
15.4.6 Checking the memory [Memory Check]
Check the memory.
[Operation procedure]
Open the Memory Check screen by performing the following menu operations.
[Menu] button → Maintenance → Diagnosis → Memory Check
1 Click on the [Memory Check Start] button.
