2.3.3 Input connections
All connections to the scanner card input jacks should be
made using appropriate low-noise coax (Model 6521) or tri-
ax (Model 6522) cables. See paragraph 1.9 in Section 1 for
cable recommendations.
WARNING
Make sure all power is off and any
stored energy in external circuitry is dis-
charged before connecting or discon-
necting cables.
2.3.4 Output connections
The supplied triax output cable should be connected to the
Model 6517 INPUT jack.
2.3.5 Typical connecting schemes
Figure 2-5 through Figure 2-8 show typical connecting
schemes for using the scanner card for amps, volts, ohms,
and coulombs measurements.
NOTE
The Model 6521 is intended for current
measurements. The Model 6522 is de-
signed for all Model 6517 measurement
functions. The Model 6517 should be pro-
grammed for the voltage or current scan
mode as appropriate. (See paragraph
3.4.4.)
