Introduction

See Chapter 1, Installation, and Chapter 2, Initial Setup, to prepare the Sentinel Flow Measurement System for
operation. When the meter is ready to take measurements, proceed with the instructions in this chapter.
Note: All inputs and outputs of the Sentinel are calibrated at the factory, prior to shipment. If it becomes necessary
to recalibrate any of the inputs and/or outputs, contact Panametrics for assistance.

Getting Started

The purpose of this section is to give a brief description of the Sentinel user program and how to use PanaView to
view and enter data.
3.2.1

Powering Up

Because the Sentinel does not have an ON/OFF switch, it will power up as soon as the connected power source is
energized.
Note: For compliance with the EU Low Voltage Directive (73/23/EEC), this unit requires an external power
disconnect device such as a switch or circuit breaker. The disconnect device must be marked as such,
clearly visible, directly accessible, and located within 1.8 m (6 ft) of the meter.
There are two methods for obtaining readings from the Sentinel:
• The built-in meter LCD Display, which is configured using PanaView
• The PanaView display on a computer screen
Note: PanaView must be installed in order to obtain flow rate readings from the meter. See the PanaView User
Interface User's Manual (910-211) for additional information.
Immediately upon power-up both the green PWR light and the red
About 15 seconds later the red light stops glowing and the software version display appears. Then, the meter
performs a series of internal checks, which takes about 45 seconds, prior to displaying the flow rate data.
Note:
If the Sentinel fails any of the internal checks, try disconnecting the power and then repowering the unit. If
the meter continues to fail any of the internal checks, contact Panametrics for assistance.
After successfully performing the internal checks, the Sentinel begins taking measurements and the software version
display is replaced by a measurement mode display.
