Operation
General
2-5
The mAs leads should always be connected in the ground return of the high voltage transformer.
Damage to the generator or the NERO mAx or inaccurate measurements may result if the mAs leads are
connected to any point other then the ground return of the x-ray tube current. Tube current
measurements should only be made on generators providing open and short circuit protection of the
metering circuit and where the circuit operates near ground potential. The polarity of the mAs input signal
is not important because a full wave bridge is used in the NERO mAx mAs input circuit.
Printer Connections
When using the NERO mAx with a printer, both the printer and the NERO mAx should be turned off prior
to connection. The NERO mAx uses a standard IBM PC printer cable. For more information on printing
with the NERO mAx, see Section 1.5--Printing.
AC Adapter
The AC adapter may be plugged into the NERO mAx at any time. For more information on using the AC
adapter with the NERO mAx, see Section 1.4--Battery Operation and Charging.
Scope Output
The NERO mAx’s scope output may be connected to a suitable oscilloscope at any time. For more
information regarding the real time scope output, see Section 1.6--Scope Output.
2.3 Using The NERO mAx
The NERO mAx uses an innovative system of menus and softkeys to provide an intuitive, user-friendly
operating environment. All measurement modes and options are displayed on the NERO mAx’s LCD and
all functions are controlled by the 5 softkeys beneath the display and the 3 keys to the right of the display.
