RETRANSMISSION (4-20 mA DC) OUTPUT CALIBRATION MODE
The ASHE Stream Selector Model STL-94 provides individual 4 to 20 mA retransmission output for each
stream. All retransmission outputs are factory calibrated and do not require recalibration at the
customer's side. So do not enter into Retransmission Calibration Mode unless the instrument requires
recalibration.
Before entering into Input Calibration Mode, ensure that a reliable 4 to 20 mA source is connected to
the instrument at the Input terminals with correct polarity.
Feed a DC current less than 4 mA the source to the instrument. The process value on the LCD Display
will show "Low".
Enter the number 05 into Select Menu by using INC key in the PARAMETER SETTING MODE SCREEN.
Press the MODE key to enter into Retransmission Output Calibration Mode.
The LCD Display shows :
