Introduction
Power Indicator
Th
e power indicator is located at the bottom left of the front panel. When
lit, it indicates that the Blood FlowMeter has power from the external power
supply.
Probe Status Indicator
Th
e probe input has an associated Status indicator. Th
is indicator is used to
indicate what is happening to the channel at any given time. Flash and color
indications are listed below:
•
Green (continuous):
Channel OK — no probe connected
•
Red/Amber (fl ashing):
Calibration in progress
•
Amber (continuous):
Probe connected and laser operating
Probe Input Connector
Th
e Blood FlowMeter is a single channel device and provides one probe input
connector. Th
e input connector is a polarized (keyed) multi-pin connector
with optical interfaces for the fi ber optics in the probe cable. Th
e probes are
designed to push and click into the connector. Do not touch or tamper with
any part of the connector as it may damage the optics or internal circuitry.
The Back Panel
Probe Calibration Button
Th
e Blood FlowMeter is designed to automatically confi gure and calibrate
itself for specifi c probes. Th
is operation requires a MLA191 Calibration Kit,
which includes a controlled concentration of latex spheres in suspension.
Th
is is discussed in Probe Calibration, page 21.
