  • Page 3: Introduction

    The PVD200 can operate with current meter velocities from less than 0.05 ft/sec to more than 20 ft/sec for a Price AA meter. The PVD200 also provides a slow-speed mode to improve measurements with extremely slow rotating current meters [velocities less than 0.25 ft/sec].

  • Page 4: Overview

    2. Product Overview Overview Any pulse type current meter can be connected to the PVD200, and after entering the pulse to velocity equations, it can display the measured velocity directly. Velocity can be either displayed in feet/sec (ft/sec) or metres/second (m/sec) and is chosen by the user in a menu.

    In Cat Whisker Fast the Status LED is Red. In Cat Whisker Slow the Status LED is off. One important operating features of the PVD200 is the ability to signal process each contact closure. Contact closures from any type of meter are inherently noisy causing miscounting or double counting.

    PVD200 will not automatically power down when Bluetooth is enabled and connected. 4.5.1 Serial Communications Interface The PVD200 can be connected to a hand-held or notebook computer or any device that can ® transmit and receive serial communications using Bluetooth using an application such as HyperTerm.
  • Page 13 If there is no contact closure detected when the measurement interval has been reached, the PVD200 will continue to send data and the user must send the ‘I’ command to abort the function. Note that the meter contact number, nn, is limited to a total of 255 counts (hexadecimal notation ‘FF’).

  • Page 14: Data Conversion Example

    Example: v1.0 4.5.2 Data Conversion Example The data format of the PVD200 is transmitted in HEX ASCII (base 16 numbers using the ASCII code which is displayable on any terminal) to provide efficiency in the number of data characters sent through the serial interface. Following is an example of the interpretation of the data.
  • Page 15 HyQuest Solutions Pty. Ltd. Data Format Notes The data format presented by the PVD200 during a measurement provides for displaying a computed velocity by an external device at a 1-second rate. The accumulating contact closure counts and time interval counts can be used in a rating equation to display velocity.

  • Page 16: Operating The Special Functions Using Serial Communications

    A laptop, desktop PC, or PocketPC using a terminal emulating package or Microsoft ’s HyperTerminal can be used to invoke the function. No menu selections in the PVD200 are needed. The selection of the meter type and turning the buzzer On and Off can all be done using the serial communications interface.

  • Page 17: Maintenance And Repair Procedure

    Allow the unit to dry out completely before reinstalling the batteries. There are no user serviceable parts inside the PVD200. If the unit does not function properly, the unit must be returned to HyQuest Solutions for component repair. The PVD200 does not require any calibration or adjustments.

    The contact time and total time shown above in the formula are expressed in terms of the number of samples measured at a sample rate of 1200 Hz as it is measured by the PVD200. A high sample rate is used to reflect a more accurate measure of the contact time and total time measured.
