Calibrate the transmitter.
Disconnect the wiring from the transmitter.
Ensure that the resistor is located on the input side of the transmitter. The resistor should be across the positive terminal and the negative terminal.
Connect an ammeter and a signal generator as you are shown in illustration 5.
Ensure that the signal generator is not generating a signal (zero Hertz).
Adjust the zero dial until the ammeter reads 4 mA.
Adjust the signal generator in order to produce an output of 5100 HZ.
Adjust the span dial until the ammeter reads 20 mA.
Adjust the signal generator in order to produce an output of zero hertz. Verify that the ammeter reads 4 mA.
The ammeter reads 4 mA. STOP.
The ammeter does not read 4 mA. Proceed to 3.
Readjust the frequency input.
Adjust the signal generator in order to produce zero Hertz.
Adjust the zero dial until the ammeter reads 4 mA.
Adjust the signal generator in order to produce an output of 5100 HZ.
Adjust the span dial until the ammeter reads 20 mA.
Adjust the signal generator in order to produce an output of zero hertz. Verify that the ammeter reads 4 mA.Note: Repeat the procedure in order to calibrate a frequency transmitter properly. Continue until both the 4 mA and the 20 mA readings are correct.
The ammeter reads 4 mA and 20 mA at the desired input frequency. STOP.
The ammeter does not read 4 mA and 20 mA. Replace the transmitter. Verify that this repair eliminates the problem.Magnetic Pickup Sensor
The magnetic pickup sensor sends the engine speed signal to the engine speed switch and to the transmitter.

Setting and Adjustment
Adjust the sensor's clearance from the flywheel.
The engine is secured. Install the sensor until the sensor contacts the flywheel.
Back off the sensor (1.2 0.1 turns).
Measure clearance between the flywheel and the
