j. Record Mode
The record mode saves minimum (MIN) and
maximum (MAX) values measured for a series of
readings. The main part of the LCD displays the
actual reading, the MAX value is constantly dis-
played on the lower left hand sub-display while the
MIN value is constantly displayed on the lower right
hand sub-display. Activate the function as follows:
1.
Depress the
REC
button on the 183.
2.
The 183 will immediately start to record and
display MIN/MAX values on the two lower sub-
displays. A confirmation beep will sound every
time a new value is recorded.
3.
Press
REC
button a second time and the AVE
(average) reading will be displayed.
4.
Press the
REC
button again to return to normal
record mode.
5.
To terminate the record mode, hold the
REC
button down for approximately 2 seconds or
turn the rotary switch to a different function.
Optional Function
(Time Reference on Min/Max Readings)
While in Record Mode push the gray button, the
two sub-displays will show the elapsed time in
seconds since the last Min/Max values were
obtained. By setting a clock at the start of the
recording session, you can easily determine the
approximate time that values were measured.
k. Compare Mode
The compare mode takes the actual reading on the
main display and compares it to LOW and HIGH
values, programmed by the user, on the sub-
displays. This is used to compare components or
measurements for acceptable readings. Activate the
function as follows:
1.
To use
Compare Mode
manually select the
correct range for the function.
2.
Depress the
COMP
button.
3.
Depress the
EDIT
button. The right hand digit
under the HIGH sub-display will start to flash.
4.
Depress the
REL%
or
HOLD
buttons until the
correct number is selected for the position.
5.
Depress the
REC
button. The next digit to the
right of 3 above will start to flash.
6.
Repeat steps 4 and 5 until the correct values
for all eight digits under LOW and HIGH sub-
displays are entered.
7.
After the correct LOW and HIGH values are
entered, depress the
EDIT
button.
8.
Measure the circuit or component being
compared to the programmed values. Results
will be displayed as PASS for the acceptable
readings, LO for low readings, and HI for high
readings.
9.
Depress the
COMP
button or turn the rotary
switch to exit the function.
