Output Calibration 

 

 

For the output calibration, follow this procedure for retransmitter output 1. 

 

The retransmitter output can be calibrated by using the Indicator input. 

 

The  hardware  configuration  for  the  input  must  be  the  same  chosen  for  the 

output  (0 to 5V,  0 to 10V or 0 to 20mA) since the Indicator will measure the output 
signal.  Therefore,  check  if  the  configurations  of  internal  jumpers  from  the  optional 
output  module  and  from  the  CPU  board  correspond  to  the  same  input  and  output 
types. 
 

Make sure that the input type was calibrated previously. 

 

Make  the  connections  listed  in  table  10  according  to  the  output  type  to  be 

calibrated.

Table 10 - I/O Terminal Connections for Output Calibration 

 

 

Enter level 6 of Calibration and select the output to be calibrated. Choose the 

type of output (0 to 20mA, 0 to 5V or 0 to 10V) and press ENTER. 
 

The  display  will  show  the  mnemonic  related  to  the  first  point  of  calibration. 

There are only two points for output calibration. 
 

For current output, the mnemonics are related to 0 and 20mA electric signals. 

For voltage output, the mnemonics are related to 0 and 5V or 0 and 10V signals. 
 

Press ENTER after the display shows the mnemonic related to first or second 

point of calibration, so that the display starts to show the output value. Then use the 
UP  and  DOWN  keys  to  set  the  output  value  to  the  electric  level  indicated  by  the 
mnemonic.  After  the  output  value  is  set,  press  ENTER.  During  the  first  point 
calibration (0mA, 0V) be careful not to saturate the output signal. 
 

Finally,  return  to  normal  mode  by  moving  down  through  the  levels  until 

reaching level zero. 

 

Return to factory calibration 

 

 

The  Indicator  stores  the  factory  calibration  parameter  values  on  the  non-

volatile memory, which may be recovered at any time. 
 

In case of a bad performance of the instrument due to an incorrect calibration, 

use the REC option. 
 

REC - is the option that allows to recover the factory calibration. 
 

Enter  level  6  of  Calibration,  and  choose  the  INPUT  or  the  OUTPUT 

option. Select the REC option and press ENTER in order to recover the values from 
factory.
