ADJUSTMENT

4.1 BEFORE STARTING ADJUSTMENT

(1) Adjustment items utilize a personal computer.

This instruction is for HX2 PSA CONTROL PROGRAM

Program. Use the latest version program. (2) Data back up is required before adjustments. (3) Allow the equipment and test instruments adequate time

(at least 30 minutes) to warm-up. (4) Confirm the set is properly connected to the specified AC

power source. (5) Use care not to disturb internal controls and parts not spe-

cifically mentioned. (6) Unless specifically mentioned in the "ADJUSTMENT PRO-

CEDURE" steps, do not change any data.

4.3.3 Data backup

Before replacing major components such as PWB ASS'Ys, UNIT or BLOCK, be sure to backup the data contained in the set. In absence of data backup, complete adjustment becomes necessary.

z PREPARATION

(1) Make sure that Version.ini file is located in the same folder of the PSA controller. (2) Remove all signal cables except for the interface cable to the PC from the main body.

z DATA SAVE

(1) Enter Stand-by mode and open the PSA controller on the PC. (2) Click [System] in the main menu. When the pull down menu is displayed, click [Backup ROM Data] and open ROM Data Up

(3) Tick [Main EEPROM] and [Sub EEPROM] in [Target EEPROM].

(4) When [Down Load] is selected, data will be downloaded in the order of EEPROM → EEPROM2 → SUB EEPROM.

(5) When the download has completed, Save Data with File Name dialog box will be displayed. Then save the data with a file

z DATA ENTRY

(1) Enter Stand-by mode and open the PSA controller on the PC. (2) Click [System] in the main menu. When the pull down menu is displayed, click [Backup ROM Data] and open ROM Data Up

(3) Tick [Main EEPROM] in [Target EEPROM]. (4) When [Down Load] is selected, Open dialog box will be displayed. Then select a file which you want to upload.

(5) The data will be downloaded in the order of EEPROM → EEPROM2 → SUB EEPROM.
