3 SERVICE T2130
NOTE: This is just checking the measuring circuit - NOT the absolute battery voltage present at the
Connection Board (6).
The special sequence of SP-29 followed by SP-20-0 may give a different battery voltage
compared to a normal read of SP-20-0 caused by an offset added by the calibration of the
T2130.
TEMPERATURE MEASURING
Test set-up: Mode 1.
A: Disconnect the PO1 on the Power Supply (4). This is the cable to the temperature sensor R45 on the
Power Amplifier (1).
Connect a resistor of 2 Kohm on the PO1 on the Power Supply (4).
B: Connect a Voltmeter to the lower end of R60, (8K2). Voltage is 2.5 Volt +/-1.7% +/- tolerances on the
2 Kohm resistor.
C: Calculate an adctemp:
Measured voltage * 255
adctemp = ----------------------------------
5.0 Volt
D: Enter SP-21-1 >ENT<.
Multiply the displayed result by 10. Compare to the calculated acdtemp. Maximum deviation is +/- 2%.
E: Reconnect temperature sensor to P.S. module P01
3.5.3.2 OUTPUT FILTER MODULE DRIVERS
RX/TX RELAY DRIVER
Test set-up: Mode 1.
A: Enter SP-29. Connect the voltmeter to U09 pin 16. Voltage is <1.1 Volt. Leave SP-29 by entering ‘ENT’.
TX/DRIVE RELAY DRIVER
Test set-up: Mode 1.
A: Enter SP-29. Connect the voltmeter to U08 pin 16. Voltage is < 1.1 Volt. Leave SP-29 by entering
‘ENT’.
OUTPUT FILTER RELAY DRIVERS
Test set-up: Mode 2.
Each of the six drivers controls two relays for switching in the lowpass filters.
A: Key in a TX-frequency in the frequency range for the specific filter.
