2 - Setting the internal clock
To set the magnetometer’s internal clock to the Julian date and time press : AUTO, TIME, SHIFT Geometrics, Inc . G-856AX Operation Manual 18 Then press : ‘day’, ‘day’, ‘day’, and then press ‘hour’ , ‘hour’ , ‘minute’, ‘minute’, ENTER. The Julian date is the number of days since the beginning of the year. For example, the Julian date for February 10 is 41. To enter the date and time corresponding to 10:35AM on February 10 you would key AUTO, TIME, SHIFT, ‘0’,’4’,’1’,’1’,’0’,’3’,’5’, ENTER. There are a number of features related to the internal clock, and they are discussed at several places in this manual. It is especially important to set the clock properly when diurnal corrections will be applied to your survey measurements because the survey and the base station magnetometer clocks must be synchronized with each other for the correction to be effective. The console’s date and time setting will be used in post- acquisition processing with the MagMap2000 software. The recommended procedure for insuring correct internal clock synchronization is as follows: Check the clock to see if it needs setting. Do this by pressing TIME. The hour, minutes, seconds will light in the FIELD/TIME display and you should see that the seconds are advancing. The Julian date will be indicated in the STATION/DAY display. Compare the magnetometer clock’s time to your watch, time standard, or your base station instrument and decide whether you need to reset the clock. Note that the display will automatically go blank 5 seconds after pressing TIME. If you decide that you need to reset the clock, choose a time in the near future when you plan to start the G-856AX clock. Then proceed with the clock setting sequence (AUTO, TIME, SHIFT , ’d ay’, + ‘day’ + ‘day’ +’ hour’ + ‘hour’ + ‘min.’ + ‘min.’). Now, wait for real time to match your clock setting. At the instant the display matches the real time standard press ENTER. When you do this, the new setting will be entered and the display will go blank . Note that G-856AX clock time does not change until you press ENTER . If you make a mistake in the time entry sequence, just press CLEAR and you will see that the old time setting is still active . Pressing ENTER just after the Julian Date is keyed in will change this number without resetting the clock. In Automatic Mode the magnetometer will increment this number every 24 hours as described below under Item 9 - Automatic reading set-up . Download 1.01 Mb. Do'stlaringiz bilan baham: |
