4.3.13 AUTO HOLD Function
The instrument can automatically retain the measured value when the test leads are handled as
described below.
1) Press the HOLD key to select Auto hold function.
(The display shows the“ A•H ” symbol.)
2) Connect the test leads to the circuit under test.
3) When the reading stabilized, the buzzer sounds.
4) Remove the test leads from the circuit under test.
5) The display shows the measured value that is retained.
You can repeat steps 2) to 4)as many times as you like as long as the display shows the “ A•
H ” symbol.
Note
• In DC/AC voltage measurement, the Auto hold function is only available for ranges greater
than the 6V range.
• This function is not available for Temperature, Capacitor and Frequency measurement.
• The Auto hold function can not be applied to unstable signals.
4.3.14 Relative and percentage calculation
The instrument can calculate relative values or difference, and percentage values from the
reference measurement values. (The range will be fixed.)
<Relative (REL) calculation>
Subtracts the reference value from the measured value to display the relative value or
difference.
1) Take a measurement to set the reference value.
2) Press the REL
/% key.
(The display shows the“ ” symbol and the sub-display shows the reference value.)
3) Take another measurement.
<Percentage (%) calculation>
Calculates and display the percentage value according to the following equation:
% value =(measured value – reference value)/reference value
1) Take a measurement to set the reference value.
2) Press the REL
/% key.
(The display shows the“ ” symbol and the sub-display shows the reference value.)
3) Take another measurement.
Press the REL
/% key again. (The display shows the“ % ” symbol.)
