Mode 6 (b110): RF Power Select: 

Set mode 

switches for mode 6 (see figure 3) then press and 
release the reset switch. There are 5 RF power 
settings available (1mW, 10mW, 100mW, 
500mW, 1W). After power up sequence, the pre-
sent RF power setting will be displayed, see fig-
ure 5.  To return to normal mode return all 
switches to b000 or to change RF power setting,  
press and release the program switch and the 
next incremented channel will be displayed. Each 
subsequent press and release of the program 
switch increments the RF power, power setting 
will wrap around from 4 to 0. When the desired 
power level is displayed, press and hold the pro-
gram switch for five seconds, the power LED will 
blink twice to indicate value has been stored. Re-
turn all switches to b000, programming is com-
plete.

(refer to label on side of unit for actual input voltage/

current, substitute value for 4-20mA below as necessary)  

 

 
 

4.3.1

  Lift Access Door to expose mode, reset, and programming switches

 

(see figure 

 

3). 

 

4.3.2

  Connect calibration source to 4-20ma input (see figure 1, and table 1)

 

 

4.3.3

  Set mode switch to Mode 2 (“Span Adjust”) – see figure 3 for proper setting.

 

 

4.3.4

  Apply power to unit or if unit is already powered – press and release the “reset 

 

switch” – after unit has completed power up sequence, apply “Zero” signal of 

 

4ma.

 

 

4.3.5

  Press and release the “program switch” – the Power LED will blink twice to indi-

 

cate value is stored.

 

 

4.3.6

  Apply “Span” value of 20ma.

 

 

4.3.7

  Press and release the “program switch” – the Power LED will blink twice to indi-

 

cat value is stored.

 

 

4.3.8

  Span calibration is completed.  Return mode switch to Mode 0.

 

 

4.3.9

  Set mode switch to Mode 1 (“Zero Adjust”) -- see figure 3 for proper setting.

 

 

4.3.10

 Press and release the “reset switch” – after unit has completed power up se

 

quence, apply “Zero” signal of 4ma.

 

 

4.3.11

 Press and release the “program switch” – the Power LED will blink twice to indi-

 

cate value is stored.

 

 

4.3.12

 Zero/Span calibration is completed.   Return mode switch to Mode 0.

 

 

4.3.13 

Check Zero/Span calibration by observing 4-20ma output of A750 Receiver at 

 

different input values of connected calibrator source (e.g. 4,8,12,16,and 20ma).

 

 

4.3.14 

If unit is properly calibrated – disconnect calibration source; otherwise, repeat 

 

calibration process – starting at step 4.3.2.
