FACTORY CALIBRATION
The ASA is set as follows:
Voltage Input Signal
No O set to the Output Signal
Input to Output Signal Gain (1:1)
The ASA can be ordered calibrated to your speci cations or you may follow the procedure below to set
your own calibration.
Be sure to check the input, output, GAIN and OFFSET speci cations of the ASA. It is possible that the ASA
cannot re-scale to your requirements.
CHECKOUT
Complete the following steps to change the calibration of the ASA. You will need a digital volt/current
meter, a 24 to 30 VDC or VAC power supply and a voltage input signal simulator.
EQUIVALENT CALIBRATION VOLTAGE
Use a voltage signal for your input signal during calibration: this makes both the procedure and the
explanation easier. If you will require a current input when you are nished, use the equation below to nd
the equivalent calibration voltage to use during the calibration procedure:
Equivalent Calibration Voltage = Required Input Signal Amps x 250
Example: 1 VDC is the equivalent calibration voltage for a 4 mA input signal (1= .004 x 250) or 5VDC is the
equivalent calibration voltage for a 20 mA input signal (5=.020 x 250).
Step 1) Trim Pot Presets
Set all pots as follows to start (These are 25 turn trim pots with no hard stops; they may make a slight
clicking sound at either end of their range):
Turn the GAIN pot Full Counterclockwise: = Gain of 1
Turn the OFFSET pots Fully Clockwise: = 0 volts o set
Step 2) Jumper Shunt Presets

Set in "E" position for voltage input.
If you require a current input, you will set this shunt in the "I" position
AFTER you are nished with the calibration procedure.
