Calibration Instructions

The SPD-108 and SPD-108L tachometers are normally factory-

calibrated to the customer-specified number of sensing teeth or

discontinuities, sensing speed, and desired numerical display.

To calibrate an SPD-108 or SPD-108L

1. Remove the sealing plug on the back of the housing.

2. Apply the calculated signal frequency to terminals 1 and 2.

A Dynalco F-16 or F-15 signal generator is ideal.

3. Select the appropriate gate time range on the 4-position

switch.

See label on back of SPD-108; SPD-108L; or Item 3, reverse

side of card.

4. Adjust the vernier potentiometer for the desired display.

Example:

If 3390 Hz = 1800 RPM, then gate time is 0.53 seconds.

1. Apply 3390 Hz to terminals 1 and 2 on tachometer (no polarity).

2. Turn the gate time range switch to (either) position number 2 to

select gate time range of 0.38–0.76 seconds.

3. Adjust the vernier potentiometer to obtain a display of 1800.
