2.4 Simplified Operation Check
Before an important measurement or after a long unused time of instrument, it is recommended to
check the ZM2376 operation by the following procedure. Check it within an application range.
1. Plug the power cord in the AC outlet and turn on the power switch on the rear panel.
Wait until the starting message disappears and the measurement screen is displayed.
2. Initialize the settings.
Press the _SHIFT_ + [INIT] keys to display the initialize menu, and press the _1_ key.
(First press the _SHIFT_ key, and then press the _0_ | [INIT] key where INIT is written in
upper place.)
3. Connect the test fixture or test leads to the measurement terminal on the front panel.
4. Attach the DUT to the test fixture or test leads.
Prepare the DUT of which value is known exactly every measurement range used. For 1kΩ
range, for instance, a value of about 1kΩ will be appropriate.
5. Switch the measurement conditions, and check that the measurement can be performed
normally.
_FREQ_ key : Display the measurement frequency setting menu and set the frequency.
_LEVEL_ key : Display the measurement signal level setting menu and set the voltage.
– – Evaluation of measured result – –
The measured value may vary depending on the connection method or whether OPEN and
SHORT are corrected or not, and accordingly an error due to these factors should be taken into
consideration. Also, as the impedance of DUT itself may vary depending on the frequency or
signal level, the DUT’s characteristics should be checked in advance.
6. Check the triggered drive timing (if used).
Press the _SHIFT_ + [TRIG MODE] keys to display the trigger setting menu, and press the
_1_ key to set the trigger source to Manual.
Press the _SHIFT_ + [TRIG MODE] keys to display the trigger setting menu, and press the
_5_ key to select S.Sync. Further, press the _1_ key to select ON, so as to make the triggered
drive valid, and then press the [EXIT] key to return to the measurement screen ([EXIT] key:
_ENTR_ | [EXIT] key where EXIT is written in lower place).
Attach the DUT to the test fixture, and observe the signal of the H terminal with an
oscilloscope.
Press the _TRIG_ key to check that the drive signal is output only at the measurement.
Thus, the simplified operation check is completed.
Finally, it is recommended to initialize the settings.
