8. Manual Mode:Press UP and DOWN Keys together, and 'CLEAr' (Clear) is shown on the display. Enter the Password (default password is 1000. Set up and clear has the same password) and it will display “CLr.I”. Press DOWN Key and meter displays “Manual”. Once manual selected it will display C1 OFF or C1.On (depends on whether the capacitor is ON or OFF). Press RIGHT key to make it ON or OFF. Continue this for other no. of relays programmed. Once the required no. of relays are switched ON or OFF display will prompt to “CLEAr.”or Manual . When display prompts to CLEAr press DOWN key and 'n' will display and Press the RIGHT key to come out.
7. Enabling and Disabling of Auto scrolling:Enabling auto scrolling: Press UP key continuously for 5 seconds or until display shows EnbL Au for upward scrolling. Press Down key continuously for 5 seconds or until display shows EnbL Au for downward scrolling.
Disabling auto scrolling: Press any key (RIGHT/UP/DOWN), display show dSbL Au and returns to normal mode.
6. Clearing the Integrator:To Clear parameters from the front panel, Press UP and DOWN Keys together, and 'CLEAr' (Clear) is shown on the display. Enter the Password (default password is 1000. Set up and clear has the same password) and it will display “CLr.I”. Press UP / DOWN Key for selecting CLr.I (Integ Clear). Once the parameter to be cleared is selected it will prompt to 'y' or 'n'. Press UP and DOWN key for changing 'y' or 'n' and Press the RIGHT key to do the operation.
