Test Products International 275 - Manual (Page 26)

Other Features (continued)
Record Mode (MAX / MIN)
Record mode allows you to record the maximum and
minimum readings measured during a test.
1. Manually select the range for the function and set
the meter up to perform a measurement as outlined
earlier in this manual.
2. Depress the MAX/MIN button and “MAX” will be
displayed along with the maximum reading record-
ed. Press the MAX/MIN button again and the display
will show MIN and the minimum reading recorded.
3. Press the MAX/MIN button again and MAX MIN will
blink and the 275 will display the measured value in
real time. Steps 2 and 3 can be repeated to read the
maximum and minimum recorded values.
If REL was activated and is being used with
MAX/MIN, REL and MAX MIN will blink and the dis-
play will show the REL value instead of the real time
reading.
5. To exit record mode, press and hold the MAX/MIN
button for approximately two seconds and the 275
will beep and return to normal operation.
Other Features (continued)
Relative mode (REL)
The Relative mode (REL) takes the reading on the dis-
play at the time the REL button is pressed and uses it as
a reference value that is deducted from all subsequent
measurements. This can be very helpful in deducting the
resistance of test leads in low ohm measurements.
1. To use Relative mode manually select the range
for the function.
2. Depress the REL button to store the reading on the
display. The “REL” indicator will illuminate con-
firming the 275 is in relative mode.
3. Now when making a measurement the value
stored will be deducted from the actual reading.
4. To see what the stored value is, depress the REL
button again and the “REL” indicator will flash and
the reading on the display will show the stored
value. Depress the REL button again to return to
REL mode.
5. To clear or exit relative mode, press and hold the
REL button for approximately two seconds and the
275 will beep and return to normal operation.
Note: Differential temperature measurements can be
made using relative mode. See the application note
on page 33 for more information.
