WARNING
To reduce the risks associated with hazardous voltage:
•
Connect the attached ground wire on rear panel to an electrical ground before
operating the analyzer;
•
Do not use if the 3M
™
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 analyzer in an explosive environment. The analyzer is not
designed to be intrinsically safe.
The following procedure zeros each voltage range, adjusts the start and stop voltage, and adjusts the offset time in
the Static Decay Time measurement mode.
Note: You must remove the charge plate to change to FIELDMETER mode to perform the following
procedure.
Voltage range zero procedure:
Perform zeroing on first power up.
1. Ground the 3M
™
Charge Analyzer 711 by attaching the ground wire with alligator clip on the rear panel of
the unit to an earth/electrical ground.
2. Remove the plate electrode (b) from the Charge Analyzer.
3. Depress the on/off button to activate the analyzer. The display will briefly indicate
CHANGE MODE OF
OPERATION
then
FIELDMETER IS ENABLED.
4. Cover the measurement electrode on the top of the unit with the red sensor cover (e).
5. Select each range by depressing the “A” button
RANGE
momentarily. Be sure to allow a brief moment
between each range selection to perform the zeroing. This completes the zeroing of all ranges.
Setting the START & STOP voltage:
Note: The Start voltage can only be adjusted from 600 to 1100 volts. The Stop voltage can only be adjusted
from 1 to 500 volts. The maximum period of time that the 711 allows for the measurement of the
start to stop voltage is 99.9 seconds.
1. Depress the “B” button (SET) to display
SETUP B
.
2. Depress the “B” button to display the
START 600-1100
voltage range menu.
3. Notice the blinking cursor under the thousandths position of the four-digit voltage value located on the
second line of the display. Change the value of this digit by depressing the “A” button momentarily.
Continue to momentarily depress the “A” button until the desired value (0-9) is obtained.
4. Depress the “B” button once to move the cursor to the next digit and adjust the value (0-9) with the “A”
button.
5. Continue adjusting the value of the remaining digits to the desired level. If you make a mistake continue to
depress the “A” & “B” buttons consecutively to obtain the desired value.
6. When the desired voltage value is obtained, continue to depress the “B” button until the display reads
A<YES
&
NO>B.
7. Depress the “A”
YES
button to verify and store the start voltage value. Depressing the “B”
NO
button
repeats the voltage value setting menu again.
8. The
STOP 1-500
voltage range menu is now displayed. Adjust the stop voltage using the “A” & “B” buttons
as described in the
Start
voltage procedure above.
9. Depress the “A” button
YES
to verify and store the stop voltage value. Depressing the “B”
NO
button
repeats the voltage value setting menu again.
