The [POS1] key
selects the 1st parameter in a column.
The [END] key
selects the last parameter in a column.
[F3] key (HOME):
This effects a return to the main menu.
[F4] key (RETUrn):
This effects a return to the parameter selection menu.
Pressing the [F1] key [SEL] acknowledges the inversely displayed measurement range for calibration. The
following display appears on the LCD:
[F3] key (HOME):
This effects a return to the main menu.
[F4] key (RETUrn):
This effects a return to the menu titled CALIBRATE MEAS. RANGES (figure 13-1).
Pressing the F1 key [INPUT] invokes the input mode, where the value of the externally connected calibration
resistance can be entered.
In this case, the function keys are redefined as follows:
Numeric keys [0] to [9] and the decimal [.] key are used to specify the value of the externally connected
calibration resistance.
The [BSP] key is used to delete the character entered last.
The [C] key is used to delete all the entered characters and repeat the input procedure from the beginning,
without exiting the input mode.
The [ESC] key is used to cancel the current entry, and exit the input mode.
The [F1] key [mOHM], [F2] key [OHM] or [F3] key [kOHM] is used to save the input value - provided that it is
valid - and exit the input mode.
Pressing the F2 [BAL] key subsequently causes the selected resistance range to be calibrated.
