the cursor.
2. Touch this key (cursor) again to enter into the number soft keyboard, input the required
average times and then press the ENTER key to confirm and return to <MEAS SETUP> page.

NOTE:
1.
When the MEAS TIME is set as 0s (i.e. this procedure is set as OFF), the Average
times can be set as 1
~
999.
2. When the MEAS TIME is not set as 0s (i.e. this procedure is set as ON), the set value
of the Average times is subject to the MEAS TIME. Specifically, the following restriction
rules are required:
(1) When the
MEAS SPEED is set as SLOW, it takes 0.06s to make a measurement, so the
restrictive relation between the Average times and the MEAS TIME is:
Average times × 0.06 <= MEAS TIME
(2) When the
MEAS SPEED is set as FAST, it takes 0.03s to make a measurement, so the
restrictive relation between the Average times and the MEAS TIME is:
Average times × 0.03 <= MEAS TIME
3. For the same reason, when setting the MEAS TIME, the above restriction rules are
also required.
3.2.10 MEAS DISP
This function is used for setting the MEAS DISP of the instrument as ON/OFF.
