Calibration Instructions

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

calibrated to the customer-specified number of sensing teeth or

discontinuities, sensing speed, and desired numerical display.

Number of

Teeth

Assumes the pickup is “seeing” the

gear of interest directly, not through

a step up or step down ratio

{

To calibrate an LST-108 or LST-108L:

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

2. Apply the calculated signal frequency to terminals A and B.

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 LST-108; LST-108L; or Item 3, reverse

side of card.

4. Adjust the vernier potentiometer for the desired display.

See below

[clockwise to increase display reading;

counterclockwise to decrease]

4-position switch

Example:

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

1. Apply 3390 Hz to terminals A and B 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.

(For example: 60/113 teeth = 0.53 sec. gate time)
