WARNING
To reduce the risks associated with hazardous voltage:
•
Connect the attached ground wire on rear panel to an electrical ground before
operating the 3M
™
Charge Analyzer 711;
•
Do not use if the analyzer 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 in the Voltmeter measurement mode.
1. Remove the plate electrode and red sensor cover from the 3M
™
Charge Analyzer 711, if attached.
2. Mount the gold cup electrode (a) to the top of the analyzer and secure with the attached long-knurled screws.
3. Insert the banana plug on one end of the Teflon
®
lead wire (f) into the ground jack on the back of the analyzer.
4. Insert the other banana plug end of the Teflon lead wire (f) into the gold cup electrode (a).
5. Ground the unit by attaching the ground wire with alligator clip on the rear panel of the unit to an earth/
electrical ground.
6. Depress the on/off button to activate the analyzer. The display will briefly indicate
CHANGE MODE OF
OPERATION
then
VOLTMETER IS ENABLED
(if cup has not been previously attached).
7. Depress the “B” button (SET) to display
OFFSET A
.
8. Select
OFFSET A
by depressing the “A” button to display
UPDATE OFFSET
menu.
Note: If you should depress the “B” button (SETUP), you will have to switch off the analyzer to get back
into the Voltmeter mode.
9. Select
YES
by depressing the “A” button.
GROUND CUP, READY >B
will appear on the display for
verification that the cup electrode is indeed grounded.
10. Select the “B” button to activate the automatic zeroing feature in the Voltmeter mode. Display will indicate
READ ALL OFFSET, UPDATING
, zeroing all ranges.
This completes the zeroing procedure. The display returns to the measurement mode.
Use
1. Unplug the Teflon lead (f) from the ground jack at the rear of the analyzer.
2. Plug the Teflon lead (f) into the cylinder electrode (c).
3. Select the desired voltage range by momentarily depressing the “A” button.
Note: If OVERFLOW occurs during the measurement select a higher range.
The charge analyzer 711 is now ready to monitor the effectiveness of static control products, measuring electrical
charge on people and conductive objects, indicating in volts.
