Step 4:
Rotate the selector knob clockwise to the “LOW
LIMIT” position of the green pass sector. The monitor’s
green “OPERATOR GROUND” LED should illuminate.
Step 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.
Step 6:
Rotate the selector knob clockwise to the “HIGH
FAIL” position. The green “OPERATOR GROUND” LED
should turn off and the red LED should illuminate and the
alarm should sound.
Step 7:
Disconnect the Monitor Calibration Unit from the
monitor.
TESTING THE MAT CIRCUIT
Step 1:
Connect the Calibration Unit’s banana plug wire
labeled “GROUND” to a known ground.
Step 2:
Connect the included banana jack to wire adapter to
the Calibration Unit’s banana plug labeled “MAT.” Insert the
wire end of the adapter to the monitor’s green terminal block
labeled “MAT” (see Figure 3).
Calibrating the Dual Operator Continuous
Monitor with Two Satellites
The Dual Operator Continuous Monitor with Two Satellites is
available as following item numbers:

Calibration Unit to the Full Time Continuous Monitor
Step 3:
Rotate the Calibration Unit’s knob switch to the MAT
FAIL 10M position. The monitor’s red “MAT GROUND” LED
should illuminate and the alarm should sound.
Step 4:
Rotate the selector knob counter-clockwise to the
MAT PASS 10M position. The monitor’s “MAT GROUND”
green LED should illuminate.

Note:
If calibrating discontinued items 19208 or 19209,
disconnect the remote jacks (if used) from the unit. Remote
jacks may cause intermittencies in calibration. Leave the
matt connection to the 19208 or 19209 in place.
TESTING THE OPERATOR CIRCUIT
Step 1:
Connect the Calibration Unit’s banana plug wire
labeled “GROUND” to a known ground.
Step 2:
Insert the Calibration Unit’s banana plug labeled
“OPERATOR” into the jack labeled “OPERATOR” on the
satellite remote (see Figure 4).

Monitor Calibration Unit to the satellite remote
Step 3:
Start the Calibration Unit’s selector knob at the full
counter-clockwise position and power the monitor. 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 operator red LED on
the monitor should illuminate and alarm.
Step 4:
Rotate the selector knob clockwise to the “LOW
LIMIT” position of the green pass sector. The monitor’s
corresponding green “OPR1” or “OPR2” LED should
illuminate.
