Product technial information：

1. Connect the input to a calibrated frequency source and apply

power. Wait 1 hour for thermal stability before monitoring the

voltage or current output.

2. Adjust the input frequency to the desired maximum and

observe that the ouput has increased and is sensing the input. If

the output does not increase, turn the sensitivity potentiometer in

a counter-clockwise direction until the output begins to change

proportionally to the input, plus another full turn.

3. Press the CAL button once to enter the calibration mode. The

yellow and green LEDs will be on.

4. Input the maximum desired frequency and press the CAL

button to store. The yellow LED will now be the only LED on.

5. Input the minimum desired frequency and press the CAL button

to store. The green and red LEDs will now be on.

Note: The most reliable way to input 0Hz is to short circuit the input

(Pins 41 & 42). It is usually easier to choose a value greater than 0Hz

(e.g.,10% of full scale) when calibrating the minimum input and

output (also 10%). When using this method signals below 10% are

still converted linearally.

6. To precisely adjust the maximum output, adjust the input

frequency until the output reads within +0.1% of the maximum

selected output range. This typically occurs near 90% of the HI

input frequency. Press the CAL button to store the value. The red

LED will now be on.

7. To precisely adjust the minimum output, lower the input

frequency until the output reads within +0.1% of the minimum

selected ouput. This typically occurs near 10% of the HI input

frequency. Press the CAL button to store the value. All three LEDs

will be on.

8. Press the CAL button one final time to exit the calibration mode.

The green LED will now be on.

9. Check the minimum and maximum input-to-output calibration.

Repeat steps 1 through 8 if calibration is not within desired

specifications.
