Peak Reset
–
During a manual balance test where Balance Duration has been disabled the M BALANCE will show
BalDur=XXXXs which means that the test will run continuously until STOPped. Pressing the PkRst
key at any time will reset the displayed peak values to zero and the timer will continue to run until it
reaches 999.9s then the decimal point will shift and the display will run to 9999s (or about 2 hours
and 47 minutes). Beyond that, an overrun error is displayed.
Plate Voltage Bar graph
–
Three ranges are provided with a maximum resolution of less than 10 volts for making very
fast assessments of plate voltage and polarity around zero.
Power
–
The unit will run on either AC or battery power. The internal rechargeable battery will supply
up to six hours of operation.
Charge Plate
–
A 6 X 6 plate comes standard with the 288. When it is detached from the base unit it comes with
the ground plane plate or can be taken off as a separate item. Mounting hardware allows the plate to
be attached to the side of the unit, connected to a tripod via ¼ -20 threaded insert or put into any
variety of situations to measure ionization. A 5-foot extension cable comes standard with the unit.
To release the detachable charge plate only, slide it forward. To remove the complete charge plate
and ground plane assembly, press the release button with a suitable tool and swing the assembly
slightly to the right.
For those space restricted applications, there are several optional plate sizes available down to 1” x
1”. Consult factory for other sizes and availability.
Grounds
–
A ground snap is provided on one corner of the ground plane and a ground jack is provided on the
back panel. The instrument chassis is normally connected to ground via the power cord during AC
operation and the ground plane is connected to the chassis when the unit is assembled. Grounding
is essential to proper operation.
Analog Output
–
An analog output jack is provided on the back panel.
