5.3 Key Operation
5.3.1 Operation Key Types and Functions
(1) Mode Key ([MODE])
By pressing [MODE] key, the operation mode changes. The current operation mode is known
through a mode lamp which is lit.
Mode is transferred in the order shown in Figure 5.2 every time the [MODE] key is pressed.
However, when a function code other than “1” is selected in each mode, mode does not change
for the first key operation and only the function code returns to “1”.
<MEAS.> <MAINT.> <PROGRAM.1> <PROGRAM.2>

(2) Function Key ([FUNC])
When [FUNC] key is pressed, the function code is transferred. The transferred function code is
displayed in the function code display. Function code contents vary in each mode (see section
5.2). The number of selectable codes also varies in each mode.
Figure 5.3 shows how the function codes are transferred by [FUNC] key operation.

(3) Data Set Keys
Operation using data set keys is valid in modes other than <MEAS.> mode. There are the
following four types of data set key:
(a) [>] key (digit selection key):
This is used when a digit to be changed displayed in the data display is selected. The digit
selected flashes. Digit selection is performed in such a manner as the digit moves from the
most significant digit in the leftmost position to the right by one digit every time the key is
pressed and returning from the right end to the left end.
(b) [Λ] key (numeric value increasing key):
The numeric value in the selected digit increments in turn every time this key is pressed and
when it reaches 9 then next time it returns to 0. In the most significant digit, “-” (minus sign)
is inserted next to 9. However, if negative numbers do not exist in the displayed data, that
sign is not inserted.
