5.

 

Rotate the selector knob clockwise to the HIGH PASS 

 

position at the end of the green pass sector.  The 

 

monitor’s green OPERATOR GROUND LED should 

 

remain illuminated.

6.  Rotate the selector knob clockwise to the HIGH FAIL 

 

position.  The monitor’s red OPERATOR GROUND LED 

 

should illuminate, and the alarm should sound.

7.  Disconnect the Monitor Calibration Unit from the monitor.

TESTING THE MAT CIRCUIT

1.

 

Connect the Calibration Unit’s GROUND test lead to a 

 

ground point.

2.  Insert a wrist cord into the monitor’s operator jack and 

 

snap it to the parking station.  This will enable the 

 

audible alarm circuit needed for calbration verfication.

3.  Connect the included banana plug / wire adapter to the 

 

Calibration Unit’s MAT test lead.  Insert the adapter’s 

 

wire terminal into monitor’s MAT terminal.

Calibrating the Dual Operator Continuous 

Monitor with Satellites

The Dual Operator Continuous Monitor with Satellites is 

available as the following item numbers:

Calibration Unit to the Full Time Continuous Monitor

4.  Rotate the Calibration Unit’s selector knob to the MAT 

 

FAIL 10M position.  The monitor’s red MAT GROUND 

 

LED should illuminate, and the alarm should sound.

5.  Rotate the selector knob counter-clockwise to the MAT 

 

PASS 10M position.  The monitor’s green MAT 

 

GROUND LED should illuminate.

TESTING THE OPERATOR CIRCUITS

1.

 

Connect the Calibration Unit’s GROUND test lead to a 

 

ground point.

2.  Insert the Calibration Unit’s OPERATOR test lead into 

 

the satellite’s OPERATOR jack.

Monitor Calibration Unit to the satellite remote

3.  Start the Calibration Unit’s selector knob at the full 

 

counter-clockwise position.  When testing the operator 

 

circuit, test only the first four limits on the Calibration 

 

Unit.  Rotate the selector knob to the LOW FAIL position.  

 

The corresponding red operator LED on the monitor 

 

should illuminate, and the alarm should sound.

4.  Rotate the selector knob clockwise to the LOW LIMIT

 

position of the green pass sector.  The monitor’s 

 

corresponding green operator LED should illuminate.

5.

 

Rotate the selector knob clockwise to the HIGH 

 

PASS position at the end of the green pass sector.  The 

 

monitor’s corresponding green operator LED should 

 

remain illuminated.

6.  Rotate the selector knob clockwise to the HIGH FAIL 

 

position.  The monitor’s corresponding red operator LED 

 

should illuminate, and the alarm should sound.

7.  Disconnect the Monitor Calibration Unit from the satellite.
8.  Perform the same procedure for the other satellite.
