Setting Up the Transducer
1. Turn the transducer power supply on. The instrument will go through
a preprogrammed power-up sequence. The internal display will
sequence through the current settings: Calibration date “
CALdAtE
”,
“
=
“, month and year “
03.1995
”(March 1995), measurement units
“
mEtErS
”(m/s) or “
FEET
”(ft/min), “=“, selected output type and
range “
0-5V
” and the time constant “
tc = 1.00
” in seconds. The
display will then show velocity readings.
2. Push
the
SET
button to enter setup mode. When setup mode is
entered, the transducer voltage/current output will drop below zero.
3. Use
the
▼
and
▲
buttons to select the desired setting.
4. Use
the
SET
button to advance to the next setup message.
Note:
The output signal is disabled during the 15 second warm-up period
and when the transducer is in setup mode.
