Figure 79 - Tiltplates: 6201-1C (ceramic), 6201-1A (Copper plated Aluminum), 6201-1S (stainless) 

 

 
It is assumed that a valid Bluetooth pairing exists between the GK-604-4 Interface 
Module and the FPC-1 (see section 2.2 for more information about establishing 
communication with the Interface Module). The recommended steps for connecting to 
and taking a reading with the Model 6101 Tiltmeter are as follows: 

1.

 

Connect one end of the 6201-3 cable to the Tiltmeter 

2.

 

Connect the other end of the 6201-3 cable to the GK-604-4 Interface Module. 

3.

 

On the FPC-1, launch the GK-604D IRA and create a new probe configuration: 

•

 

Using the Context Menu (see section 3.2.1), after highlighting the Probe 
Library, select the “Add Probe” menu item to create a new probe.  

•

 

Name the new probe and select “Tiltmeter” for probe type.  

•

 

Using the calibration sheet as a guide, enter the “Zero Shift A” and “Gage 
Factor A” parameters. Leave the B channel parameters at zero.  

•

 

Tap “Save Settings” to save the new probe configuration. See section 4.2 for 
more information about probe configuration.
