ADDITIONAL INFORMATION
1. Disconnect the wires from the back of the read-out.
2. Connect an ohm meter to the wires.
3. The ohm meter should indicate between 500 and 1,000 ohms.
4. If there is a good reading on the ohm meter, then the read-out
is faulty. If the reading is bad, then the sensor or wire is faulty.
1. Disconnect the wires from the back of the read-out.
2. Attach a low range AC Analog Voltmeter to the wires. If the sensor is operating
properly, you will achieve these approximate reading: 8-9 MPH = 0.15 VAC rms,
17 MPH = 0.31 VAC rms, 51 MPH = .97 VAC rms, 102 MPH 2.0 VAC rms
3. If the sensor delivers these approximate readings, then the read-out
is faulty. If the sensor does not produce these readings, then either the
sensor or the wire is faulty.

Maximum Instruments are accurate and reliable. Most problems that occure are due
to loose or corroded connections. If, after checking the connections, there is still a
problem, determine if the problem is with the sensor or the brass read-out.
The Sirocco is a self-powered wind speed measuring instrument. It does not need
batteries or an external power supply. In normal operation it requires no maintenance.
