PROBE CONNECTOR
Front panel 10-pin connector. Accepts research
perivascular Flowprobes and extension cables with
male CRA 10-pin connectors. Conversion cables are
available for other congurations.
AUTOMATIC ADJUSTMENTS
Probe size identication and corresponding ow
output ranges. Volume ow calibration of applied
Probe.
DIGITAL DISPLAY
4-Digit (14 segment) LED displays Flow / Probe data
/ Error Messages
Bar Indicator Light: Displays received signal
amplitude for continuous monitoring of Probe
signal quality
ANALOG DISPLAY
Taut-band needle (-0.2 volts to +1.2 volts ) displays
Flow / Received Signal Amplitude/Calibration
information
MODE BUTTON CONTROLS
Select modes of operation of displays and outputs
● MEASURE MODE: Displays current volume ow
values. Indicator light bar shows received signal
strength
● TEST MODE: Displays Probe size & received signal
amplitude
● ZERO MODE: Sets outputs to zero vlots to
calibrate external recording device
● SCALE MODE: Sets outputs to scale factor ow (1
volt) to calibrate external recording device
FILTER PROPERTIES
● 0.1, 10, 40 Hz: 2nd order Butterworth, with a
third passive pole at 160 Hz
● 160 Hz: 3rd order Butterworth
ZERO ADJUST
Recessed momentary push button to zero ow
reading at stopped ow
LOW RANGE
Low Range increases ow gain by a factor of 4
INVERT
Invert the polarity of analog ow outputs and ow
displays
SIGNAL OUTPUTS
Up to 8 accessible signals via 400-Series Console’s
back-panel terminal block: Pulsatile Volume Flow;
Mean Volume Flow, Received Signal Amplitude (2);
Phase (4)
ULTRASONIC FREQUENCY RANGE
600 KHz to 14.4 MHz; Probe size dependent.
FLOW OUTPUT
Front panel mounted BNC output connector & rear
panel terminal block:
● Pulsatile/Average Volume Flow
● Filtering controlled by front panel selectable
lter
● Voltage range: -5 to + 5 volts
● Output resistance: 500 Ohm
● Full Range for Flow: -5 to +5 V (bidirectional
ows, with range of 5 x scale factor ow)
AUTOMATIC DIGITAL PROBE ID & CALIBRATION
TS420 circuitry reads Probe operational data (size,
scale & calibration) programmed in the Probe’s
EPROM.
● Probes with 10 or 12-pin connectors: EPROM
installed in the connector.
● 4-pin Probe connectors require separate EPROM
calibration key
CAL KEY PORT: Front panel socket accepts 3-pin
EPROM calibration keys for Flowprobes with 4-pin
connectors. Flow Module reads and uses “CAL
KEY” data if both a separate calibration key and
connector EPROM are present.
SYNCHRONIZATION
Rear panel jumpers select synchronization mode
● Self-Triggering Mode: “SYNC IN” to “SYNC OUT”
jumper on each Module
● Sequential Triggering Mode: “SYNC IN” crossed
to “SYNC OUT” between Modules
