Parameters Screen
This screen allows many of the parameters of the Hexcorder Pro to be set, such as alarms, GPS, etc.
AC Frequency
The Hexcorder Pro uses software filtering in conjunction with hardware filtering. For the software
filtering to work properly it needs to be configured to the local AC frequency. Select either 50Hz or
60Hz depending on the power grid in your area.
Alarms
The Hexcorder Pro has 3 separate alarm features to help you detect and diagnose potential survey
issues or equipment problems. Each alarm can be activated or disabled by tapping on it.
•
Low Potential Alarm
– sounds if the CIPS potential changes by 50% from the previous
reading. This may indicate poor ground contact causing a misread, or a cable failure.
•
Broken Wire Alarm
– sounds if three readings are taken without a change in the
chainage count. Under normal conditions multiple readings without the chainage
increasing would indicate a broken trailing wire.
•
DCVG Defect Alarm
– sounds if the DCVG levels exceed the user-selected value. The
alarm threshold value is below the DCVG defect enable/disable button.
o
Tap on the value to enter a new value in mV.
Show GPS Coordinates in DMS Format
The user can choose to have the GPS coordinates displayed and stored in the Degrees, Minutes and
Seconds (DMS) or the more commonly used Decimal Degrees (DD) during the survey.
