Press the [HOLD] key, and "LOLD" will be shown on the LCD to indicate that the data hold
function is activated. And measurement results for the main and secondary parameters are those
displayed before pressing the HOLD key.
Turn off reading hold:
In hold mode, press again the [HOLD] key, and "HOLD" disappears from the LCD, the instrument
returns to normal measurement mode.
2.5 Data recording function
If the measurement data of the DUT see poor stability and fluctuate within a certain range, use the
data recording mode to acquire the readings. In the data recording mode, the maximum, minimum
and average can be dynamically obtained within a certain range.
Turn on the recording function:
Press [RECORD] key to turn on the data recording function, and the recorded value is shown on
the secondary display, then press the key to select the display of the maximum, minimum, or
average in successively.
This function records the maximum value, minimum value of the main parameter and the average
value of the last ten tests.
Note: After changing the type of the measurement parameter, it will
automatically exit from the data recording function. This function cannot work
if the main parameter select as Auto.
2.6 Correction function
The correction function includes the open and short circuit. By correcting it can effectively reduce
the error of distributed parameters caused by the test line. The short circuit correction can reduce
the impact of the contact resistance and lead resistance on the measurement of low impedance
element. The open circuit correction can reduce the impact of the distributed capacitance and
resistance between the two ends of the test line on the measurement of high impedance element.
The method of correction is shown as follows:
1. Before entering the correction function, please ensure that the test terminals are open- or
short-circuited. Long press [REL] key to enter the correction interface.
