FUNCTIONALITY

The GDT100 Grout Detector uses sensors attached to the Cable Anchor to detect sufficient grout is pumped to cover the full length of the Cable Anchor. Up to 3 colour coded sensors are installed to measure at the start, center and end of the Cable Anchor. Anchors with the grout sensors may be purchased from Bokarea.

Powering Up

The GDT is shipped with rechargeable Lithium Polymer battery. The unit is on and in sleep mode with only its real time clock running. There is no need to switch the Unit on. Charging is done through the USB port either connected to a PC or a wall adapter with a USB connection. After pressing the “Check” button, the Status indicator might flash red and then change to green, indicating it is almost time to charge the GDT.

If the “Check” button is pressed and the “Status” LED lights up RED, the battery must be charged before any other tests can be done. Under normal operation (40 readings per day) the battery should last for 14 days before needing a charge. The Unit takes about 4 hours to charge completely from a discharged state. The “Charge” LED should be Red while the GDT is charging and turn green when charging is completed.

The following should be visible on the GDT100:

The “Status” LED should light up Green (If not refer to troubleshooting below).

All channel Status indicators should light up from the bottom to the top in sequence.

The final status of each channel shall now be shown for 5 seconds

All LEDs switches off to preserve battery power

Installation Mode

When the INSTALL button is pressed, the Detector first checks that no grout is present at any of the sensors. Only then will it allow the grout-pumping-process to start and runs over the full duration to the end, indicating as each sensor gets covered with grout.

The button is pressed again to stop measurement, as the process is stopped. A record of this pumping-process is stored in memory for downloading at a later stage, as evidence that the Cable Anchor is fully covered in grout. Prior to installation, the Check Mode may be used to check that the sensors are in place.

Downloading Of Data

The application can be installed on any PC or Laptop with either Windows 7 or 10. The application auto-detects to find the Detector and displays the serial nr., number of records found, current date setting, and version information. A standard Mini-USB cable is used for both downloading of records as well as charging the battery. The Detector can either be charged from a PC, or any cell phone charger with the standard USB 5V output.
