Signal limitations
CAUTION
To prevent damage to the Model 2000-SCAN, do not exceed the maximum
signal level specifications of the card.
Relay input signal limitations
Channels 1-10 are all relay inputs. To prevent over-heating or damage to the relays, never
exceed the following maximum signal levels for these channels:
DC signals: 110V DC, 1A switched, 30VA (resistive load).
AC signals: 125V rms or 175V AC peak, 1A switched, 62.5VA (resistive load).
Scanner card detection
Power-up detection
The scanner card is detected only at power-on. If the card is plugged in after the power is
turned on, the card will not be recognized as being present by the multimeter.
CAUTION
Plugging in the scanner card with power turned on may result in damage to
both the Model 2000-SCAN and the multimeter.
If the card is not present at power-on, scanner bus commands or queries will generate a
“Missing hardware error”, and front panel operations pertaining to the scanner will inform you
that no scanner is present.
Scanner option bus query
*OPT? is an IEEE 488.2 common query which will allow you determine whether or not a
scanner card is installed. The response to this query indicates whether or not a scanner card is
present as follows:
•
0: Scanner not installed.
•
200X-SCAN: Scanner installed. (The Model 2000 does not distinguish among scanner
cards.)
Refer to Model 2000/2001/2002 manuals for more details on using the *OPT? query.
