EZ2 Calibration Wizard

SUMMARY

The H5001EZ2 gauge contains a wizard to aid in the calibration process.  After completing the wizard all calibration data can be exported to a USB stick via the front USB port on the gauge.  The calibration file can then be imported into the Humboldt Gauge Assistant software omitting the need for manual data entry.  

Please note, the Calibration Wizard does not have to be used to calibrate the gauge.  The calibration can be performed manually similar to the calibration process performed on the EZ gauges which consists of multiple statistical counts and measurements.

In this document Calibration Wizard will be references with CW and Calibration Process will be referred to as CP.

REQUIREMENTS

Gauge Assistant Version 4.5.75 or greater.

Latest EZ2 firmware version.

Please visit Nuclear Gauge Software, Nuclear Density Gauge Firmware (humboldtscientific.com) to download latest firmware and software.

SOLUTION

The CW can be found by navigating to ENGINEERING (F3), CALIBRATE (F2), and then CALIBRATION WIZARD (F4).

Once in the CW the menu the following actions can be performed: start a new calibration, continue a calibration in process, or export a completed calibration. 

The calibration progress is retained if the gauge goes to sleep or powers off.  Performing a new calibration and then choosing a rod type will delete any previous calibration progress.

Existing calibrations are not overwritten or affected during the CW process.

NEW CALIBRATION

1. In the CW select NEW CALIBRATION (F2).
2. A prompt will display confirming overwrite of existing calibration progress (Image 2).
3. Press F2 to select the rod configuration on the gauge (Image 3). 
4. Press F4 to start a new calibration for the gauge.
5. A new CW data set is now started.
6. The CW will proceed to the CALIBRATION PROCESS menu.

RESUME CALIBRATION

1. In the CW select RESUME CALIBRATION (F3).
2. the CW will proceed to the CALIBRATION PROCESS menu.

CALIBRATION PROCESS

The CP menu will allow you to perform all steps necessary to gather the calibration items for the gauge's calibration.  Statistical counts and block measurements at the necessary depths are gathered and recorded during the CW process.

STATISTICALS

The STATISTICAL counts, INITIAL (F2) and FINAL (F4) option will display the measured DC and MC counts (Image 5 - 6).  Within the INITIAL or FINAL STATISTICAL COUNT screen, press F4 to begin measurements.  If a statistical count has not been completed, the DC and MC value will read NA or zero.

BLOCK MEASUREMENTS

The BLOCK MEASUREMENTS (F3) in the CP menu will allow you to collect measurement results at the depths and on the block types you will be using for calibration.

In the BLOCK MEASUREMENTS menu screen the block type will need to be selected first with the F3 key and then proceed to the NEXT screen with the F4 key (Image 7).

After selecting the block adjust the rod to the correct depth, if the depth is in manual mode, the F3 key can be used to adjust the depth.  Press the F4 key to perform a measurement at that depth (Image 8).  If a depth measurement has not been completed, the DC and MC value will read NA or zero.  Press the MAIN MENU button to go back to the block selection screen to change blocks.  Press the MAIN MENU button again to go back to the CP menu screen.

COMPLETION

The calibration values required by Gauge Assistant will be completed when initial and final statistical counts have been completed as well as all the measurements for each block at all depths.  Only perform block measurements for the blocks available.

EXPORT CALIBRATION

Insert a USB stick in the front panel of the gauge.  Press the F4 button at the CP menu screen to export the calibration values to the USB stick.  A message will be displayed indicating results of the export (Image 1). 

The file exported will be in CSV format and will contain the serial number of the calibration in the file name information.
