2.3 Turn on the Instrument
Connect the power supply between the instrument power source and the instrument.
The instrument enters its INITIALIZE mode that lasts a few seconds per channel. As
each channel in the instrument is initialized, the transducer's serial number may be
seen on the display if the transducer has a
Signature Calibration
Module in it.
When the instrument enters its normal operating mode (RUN mode), you will see the
following format on the front panel display:
1
•
00000. PSIG
"
where:
•
Channel number:
“1” is the channel number.
•
Value type:
The next character indicates the nature of the following value.
A blank character indicates the tracking value. The instrument is “tracking” the sig-
nal, continuously updating the display in response to the signal from the trans-
ducer.
A “
•
" character indicates the peak value (highest value seen since the [CLEAR]
button was last pressed).
A “
–
" character indicates the valley value (lowest value seen since the [CLEAR]
button was last pressed).
•
Data value:
“00000.” displays the value from the transducer in engineering units.
•
Units label:
“PSIG” indicates the engineering units being used (up to 4 charac-
ters).
•
Tare indicator:
A “
"
“ symbol indicates tare is off; a “
Ë
“ symbol indicates tare is on.
NOTICE
If the channel’s display flashes “
APPLY 00000.
” (or some other load value), the
instrument has detected a transducer other than the one which was last cali-
brated with that channel. The instrument is prompting you to apply the
requested load to the transducer so that a “mV/V Calibration” or a “Shunt Cali-
bration” can take place.
After making certain that the correct transducer is connected to the Input Chan-
nel, press the [ENTER] button after you have applied the requested load to per-
form the calibration.
NOTICE
If the instrument displays error code 57 or 68, it has detected a transducer
other than the one which was last calibrated with the Input Channel. Further-
more, the channel cannot perform an automatic calibration because its calibra-
tion type has been set to “Known Load Calibration”.
Either re-connect the correct transducer to the channel, or see “
Menu Item” on page 60 to select another calibration type.
