Setup
The following procedure activates the 3M
™
Charge Analyzer 711 for use with the
3M
™
Remote Field Sensor Probe 711RS.
1. Turn off the Charge Analyzer 711.
Note: If the plate electrode is not attached to the Charge Analyzer 711, place the red cover over
the measurement electrode to prevent accidental damage.
2. Insert the 4-Pin plug (observing keyed position at bottom of socket) of the Remote
Field Sensor Probe 711RS cable into the 711RS socket on the rear of the Charge
Analyzer 711. Tighten the outer shell onto the socket (clockwise motion), until
secured.
3. Ground the unit by attaching the ground wire with alligator clip on the rear
panel of the unit to an earth/electrical ground.
4. Press the on/off button to activate the 3M
™
Charge Analyzer 711. The display
will briefly indicate RECEIVED DATA WAIT.
5. The display will next indicate EXTERN EFM, A<OFF & ON>B. Press the
“B” button (ON) to activate the Remote Field Sensor Probe 711RS. Selecting
the “A” button (OFF) will deactivate the sensor and return the Charge
Analyzer 711 to an internal measurement mode.
6. When ON is selected the display will indicate EXT. EFM, D = CM,
A<CHANGE, & OK>B. Select the desired measurement distance by
pressing the “A” button (CHANGE) momentarily until desired distance is
displayed.
Note: This value represents the distance in centimeters between a charged surface and the
sensor head.
7. Press the “B” button (OK) to select. The display will briefly indicate
PARAMETER CHANGED when distance value is changed.
8. The display now indicates external field mode, distance, and measured
voltage. To change the distance setting again while in the external field mode,
press the “B” button momentarily and repeat steps 5-7.
To reduce the risks associated with hazardous voltage:
• Connect the attached ground wire on rear panel to an electrical ground before operating 3M
™
Charge
Analyzer 711
• Do not use if the Charge Analyzer 711 housing or power supply are damaged;
• Do not attempt to modify or repair – no user serviceable parts inside – contact 3M Service for repair.
To reduce the risks associated with fire or explosion:
• Do not operate the Charge Analyzer 711 in an explosive environment. The Charge Analyzer 711 is not
designed to be intrinsically safe.
