Set Date & TimeThe date and time are accessible via the commands menu along the top menu barof the PSY1 software. The date and time can be automatically set to the date &time of the computer that the PSY1 is connected to by selecting the option"Update Computer Time". An alternative option is provided to update theinstrument to a user defined time. This is very important as Psychrometers areoften deployed in regions away from your usual office or local time zone. The day,month and year can be set by clicking on the cell and using the arrows to scroll tothe required values. This is the same for both hours and minutes. Alternatively,you can type the value directly into each cell. Then click update and the new date& time will be saved to the real time clock of the PSY1’s microprocessor.Power ManagementThe PSY1 logs the instrument's internal battery voltage, the external chargingsupply voltage and external charging current. The battery voltage and externalsupply voltage are automatically selected in SD Card logging options andcannot be disabled. These parameters are set to be helpful in troubleshootingsuspect logging problems that typically can be caused by power supply issues.24ICT InternationalEnabling better global research outcomes in soil, plant & environmental monitoring.
