Magnetic Switch
The magnetic switch enables scroll lock of display items as well as manual switching
between display modes. The magnetic switch is located near the front of the meter face in
the 10 o'clock position.
Scroll Lock
When the magnetic switch is activated for one second and removed, the “ScrLoc” message
appears on the LCD and the display locks on the current display item. The value displayed
on the locked screen will continue to be updated every second. The user may scroll to the
next item by again momentarily activating the magnetic switch. The display will remain in
the scroll lock condition until a mode timeout occurs or until the display mode is changed.
Changing Display Modes
When the magnetic switch is activated for four seconds, the display may indicate the
“ScrLoc” condition (if not already in scroll lock) and then, enter into a display mode
selection menu. The menu options are: “SELnor”, “SELALt”, and “SELtooL”. The desired
mode can be selected by removing the magnet when it is being displayed.
Mode Timeout
When the display is put into display modes other than Normal display (Alternate, Toolbox,
Scroll Lock, Test, or Test Alternate display modes), the meter will return to normal
operation after a programmable Mode Timeout expires. The Mode Timeout can be
configured from 1 to 255 minutes using the meter programming software.
Normal Display Mode
The Normal Display Mode is the default display when the meter is energized and when the
meter is in Normal Operating Mode. When Mode Timeout occurs from any other display
mode, the display returns to Normal Display Mode.
