RELATIVE MODE
(Continued)
Relative Mode – Menu System
In some cases you may wish to set a pre-determined relative value. The
relative value can be set precisely from the menu system.
To set a pre-determined relative value from the menu system:
1) Select ac or dc mode for all channels.
2) From the main menu, choose RELATIVE.
3) Use the “checkbox” to activate a channel for relative mode.
4) Position the “pointer” over the word “
scale”
and press the
ENTER key to advance the scale of the relative setting. As you
press the ENTER key, the decimal point and/or unit multiplier in
the relative setting will advance.
5) For dc mode operation, position the “pointer” over the polarity
indicator and press the ENTER key to change the setting.
6) Position the “pointer” over each digit in the relative setting and use
the ENTER key to advance the number.
7) Exit the menu system.
Upon return to the measurement screen, the relative function is enabled
and the ‘relative value indicator” shows the setting selected in the
RELATIVE menu.
Adjusting the Relative Value from the Measurement Screen
Once the relative value is set, either from the front panel or from the
RELATIVE menu, its value may be adjusted by using the MANUAL
ADJUST keys. The right MANUAL ADJUST key will add to the relative
value, and the left MANUAL ADJUST key will subtract from the relative
value
