4. Preparations
4-4. Diagnostics
Before performing the operations described in the following chapters, perform the diagnostics to make sure
that the recording unit is functioning correctly.
Diagnostics : HDD recording/playback check, Recording/playback amplifier check
Required time : Approx. 1 min.
During the diagnostics, the recording unit actually records a signal on the cartridge and plays it back. Be
sure to insert the cartridge before performing the diagnostics.
For the diagnostics procedure, see “14-7. Executing Diagnostics (Diagnostics)”.
4-5. Calibration
This measuring unit was calibrated prior to shipment, and these settings are stored in memory. While frequent
calibration is unnecessary, the measuring unit should be calibrated a few times a year if necessary.
. To perform calibration, first enable calibration using the DIP switches on the rear of the measuring unit.
(See section 3-2-2.) Calibration cannot be performed if the calibration function is disabled with the DIP
switches.
. After the power is turned on, wait at least 15 minutes before performing calibration.
. Perform calibration in the environment where it will actually be used.
. If you stop calibration before it is completed, turn the power off and then on again before using.
For the calibration procedure, see “14-5. Executing Calibration (Calibration)”.
4-6. Required Settings Before Recording
Before starting to record data, be sure to set the following items:
. Setting the Recording Unit Clock (section 11-1)
. Setting the Recording/Playback Speed (section 12-3)
. Setting the Number of Recording Channels (section 12-4)
. Setting the Input Range (section 12-5)
. Setting the Input DC Offset (section 12-6)
. Setting the Input Format (section 12-7)
. Setting the Test Signal (section 12-11)
If necessary, make other settings based on section 6 to 14.
c
24 V power is supplied to BNC cable when the recording unit is set in E-E, REC-PAUSE or REC mode
during IEPE input (IEPE or TEDS). Be sure to check the input format when connect a signal source to the
INPUT connector.
In order to stabilize the DC bias of the IEPE sensor, make a recording after warming up the unit sufficiently
with E-E mode.
