Our calibration Stands serve 3 important functions when calibrating a variety of Acoustic Current Profilers

1. Improve upon the overall error associated with HARD and SOFT IRON CALIBRATIONS.

2. The smooth rotation and balanced platform allows for a slow and stable calibration.

3. The ease by which you can load and unload the instruments will save time and energy.

Increase calibration efficiency and save time.

Minimize the physical man-handling and the backstrain associated with the calibration process of heavy profilers.

LR-1 (Long Ranger) Calibration Stand

Designed to make it easier to perform hard and soft iron calibrations for the Teledyne Long Ranger Acoustic Doppler Current Profiler, our modular system design easily converts from an Upward to a Downward Looking Calibration Configuration.

AVAILABLE IN ONE OR BOTH CONFIG. OPTIONS:
The LR-1 Turntable can be ordered in your
preferred configuration(s):
LongRanger A B
A. Upward Profile (LR-1 A)

B. Downward Profile (LR-1B)

C. Or BOTH Profiles (LR-1AB)

The LR-1 can be supplied with both adapters so you have the flexibility to calibrate for either upward looking or downward looking configurations. Switching profiles is a simple task of changing out the appropriate adapter. Both adapters easily bolt precisely onto the turntable of the LR-1 base.

A Clear Benefit of Calib Designs Calibration Stands:
 
Over the course of an ADCP deployment, the battery packs will change their magnetic alignment as the voltage drops over time. The effect of this change is an increase in the overall error evident when a post calibration check is performed and compared to the pre calibration done prior to deployment. The best way to minimize the impact this change in magnetic alignment will have on the data set, is to improve on the calibration performed when new batteries are installed.

Stability of the instrument during the calibration process, as well as a non-magnetic calibration site, is paramount to getting the lowest overall error value. Starting with the lowest overall error at the beginning of a deployment will minimize the impact of the magnetic change throughout the deployment. The resulting data sets collected will therefore be more accurate.

Our calibration stands offer the best way to maintain the stability of the ADCP throughout the calibration process. Calib Designs goal was to come up with designs that combined vertical stability with a smooth horizontal rotation. The LR-1 and WH-1 Calibration Stands are proven results of this achieved goal.
