5-9 L/C Calibration
In order to improve the accuracy of a high / low impedance,
Recommend doing open / short calibration
Before measurement.
Open / short calibration procedure:
1)
Simultaneously push " AC / DC " and " REL " button more
to start open / short calibration,The display will show "OPEn",
than 2 seconds, then push "ENTER" key once,LCD will display 30,
and the countdown to zero,
2)
The display will show " Short ", set the input of a short circuit,
then push the " ENTER " key once,LCD will display 30, and the
countdown to zero, then the calibration data is saved to the
EEPROM, complete the calibration.
5-10 Frequency Measurement
1)
Connect BLACK test lead into " COM " terminal ( 3-12, Fig. 1 ).
2)
Connect RED test lead into " Hz " terminal ( 3-11, Fig. 1 ).
3)
Select the " Function rotary switch " ( 3-10, Fig. 1 ) to the
" Hz " position, LCD will show the " Hz " marker.
4)
When LCD show the " AUTO " marker, the meter is
under the " auto range " mode. Meter will select the
suitable measurement range automatically.
5)
Under the operation of " auto range " mode, push the
" Range button " ( 3-6 Fig. 1 ) once will execute the
" Manual Range " mode and hold the range, the LCD will
show the " MANU " marker.
Under the manual range operation, push the " Range
button " ( 3-6 Fig. 1 ) > 2 seconds, will return to auto
range operation.
