Changing Alpha or Numeric Settings
The process of changing alpha or numeric settings is simi-
lar to that of changing configuration parameters, except
that there are more choices because there may be multi-
ple characters to change, and each character may range in
value from 0 to 9, and/or A-Z.
Example
Suppose you want to change the regulator Forward Volts
setpoint from 123.0 volts to 122.5 volts. Setpoints are con-
tained in the <REGULATOR> Menu, so you need to view
that Menu.
1. Press the Menu key twice to return the display to the
<METER> Menu.
2. Press the ¾ key repeatedly until <REGULATOR> is
viewed.
3. Press the À key until FwdVolts: 123.0 appears.
4. Press the Change key to activate Change mode. (The
flashing digit indicates the digit to be changed.) Fwd-
Volts: 123.0
appears. Note: the underscore in this
section of the manual (in this case under the 0)
denotes flashing.
5. Press the ¿ key five times to increment the digit from
0 to 5.
6. Press the ½ key to step left one digit. FwdVolts:
123
.5 appears. The digit 3 is flashing to indicate that it
can be changed.
7. Press the À key to decrement the digit from 3 to 2.
8. Press the Save key to make the change take effect.
FwdVolts: 122.5 appears. The flashing stops to indi-
cate that the change is complete.
3.5 Using the Fast-Path Keys to View/
Change Data Items
Fast-path keys are the labeled keys on the middle portion
of the MJ-4
Control Panel, such as the Voltage Level key.
Use the Fast-path keys as a shortcut to certain frequently-
used data items. Simply press the fast-path key and the
desired data item appears immediately.
After viewing an item with a fast-path key, the change pro-
cedure is the same as the one just described. In the previ-
ous example, the Voltage Level fast-path key would
replace steps 1-3 and save a number of key strokes.
