2. Adjust the display reading using the ADJUST buttons.
Each momentary press of the ADJUST A button will
increment the reading by one unit (value is determin-
ed by range and cursor position). For example, with the
instrument on the 2OmA range and the cursor osition-
ed on the thousanths digit (second digit from
tl?e right),
each press of ADJUST A will increment the reading by
&A. Conversely, each momentary press of ADJUST V
decrements the reading by one unit. The exception to
this rule is the least significat digit that changes by five
units when an ADJUST button is pressed. The ADJUST
buttons also have auto-repeat capability. That is,
holding in an ADJUST button will cause the reading to
increment (A) or decrement (V) automatically.
Notes:
1. Polarity of the reading can be changed by pressing the
* button.
2. Polarity of the reading will also change when the display
is adjusted past zero.
3. The display reading cannot be adjusted past the liits
of the range. However, range changes can be made at
any time.
4. If the instrument is in OPERATE, the output will change
as the display reading changes.
3.5.2 Keypad Method
Refer to Figure 3-7 and perform the following procedure
to enter a reading on the display:
Enable the keypad by pressing KEYPAD/ENTER.
The KEYPAD light will turn on and a segment of the
most significant digit will flash to indicate the position
of the cursor.
Key in the reading using the numeric data entry but-
tons.
With the cursor at the most signficant digit, key in the
desired number by pressing the appropriate number
button (0 through 9). The rest of the display digits will
zero and the cursor will move to the next less signifi-
cant digit. Key in as many numbers as necessary. The
least significant digit can only be a 0 or a 5. Keying in
0 to 4 will set that digit to 0, and keying in 5 to 9 will
set it to 5.
Enter the keyed in reading by again pressing KEYFAD/
ENTER.
The new reading will be entered and keypad will
disable. Prior to this step, the display reading
was
changed, but the output was not affected.
Notes:
1. Press the * button to change the polarity of the display
reading.
2. Range changes can be made with the keypad enabled.
3. A keyed in reading can be cancelled by pressing
(SHIFT) CANCEL. The keypad will disable and the
display will return to the reading that was on the
display before keypad was enabled.
4. Pressing any function button is the same as pressing
(SHIFT) CANCEL (see Note 3), however, the inshw
ment will go to (or stay at) the selected function.
