Note: b000 is binary 000, the decimal equivalent of decimal 0. The least significant bit 
is switch position 3. 

 
Mode 0 (b000): Normal operation

; this mode is for standard 4-20mA and switch 

status operation.  The unit is normally left in this mode.  

 
Mode 1 (b001): Calibration mode Zero adjust

; See Section 4.3 for Zero/Span Cali-

bration.  

 

Mode 2 (b010): Calibration mode Span adjust

; See Section 4.3 for Zero/Span Cali-

bration. 
 

Mode 3 (b011): RF Channel Select: 

Set mode switches for mode 3 (see figure 3) then 

press and release the reset switch. There are 8 RF channels available, 0-7. After 
power up sequence, the present RF channel will be displayed, see figure 4.  To return 
to normal mode return all switches to b000 or to change RF, channels press and re-
lease the program switch and the next incremented channel will be displayed. Each 
subsequent press and release of the program switch increments the RF channel, chan-
nels will wrap around from 7 to 0. When the desired channel is displayed, press and 
hold the program switch for five seconds, the power LED will blink twice to indicate 
value has been stored. Return all switches to b000, programming is complete.  

The RF 

channel must match the RF channel on the receiver.

  Refer to A750 Receiver manual 

for RF Channel Select procedure.

Mode 4 (b100): RSSI mode: 

 Set mode switches 

for mode 4. In this mode the RF field strength can 
be monitored on the model A750 receiver.  The 
A750 receiver must also be in RSSI mode for 
proper operation. Refer to A750 Receiver manual 
for RSSI Mode procedure.  RSSI Mode can be 
helpful during installation for antenna alignment.  

 
Mode 5 (b101): Demo mode

: Set mode switches 

for mode 5. All inputs are automatically simulated 
in the following sequence: 4.00mA, 20.00mA, A1 
closed, A2 closed, 20mA 4.00mA, 20mA, A1 
open, A2 open, 20.00mA, and repeat.  All input 
connections are ignored in this mode. Return all 
switches to b000 when demo is complete.
