Connecting the Logic Probe
High-speed logic probe (700986)
1.
Attach the accessory connecting lead (IC clip or alligator clip) to the logic probe, and lock
the connector by clamping the lever inwards. To release the connecting lead from the logic
probe, pull both levers outwards. Continue with step 3.
Isolation logic probe (700987)
1.
Connect the measuring lead to the input terminal of the logic probe.
2.
Set the input switch. The threshold level is set to 50 VAC
±
50% (Hi : 80 to 250 VAC, Lo :
0 to 20 VAC) and 6 V
±
50% (Hi : 10 to 250 VDC, Lo : 0 to 30 VDC) when set to “AC” and
“DC,” respectively.
Connecting the logic probe to the Logic Input Module
3.
Turn OFF the instrument.
4.
Connect the end with the 26-pin connector (clamp filter with ferrite core, parts No.
A1190MN) of the logic probe to the input connector of the Logic Input Module.
5.
Turn ON the instrument.
To the input connector of
the Logic Input Module
Note
• Each bit is displayed as “L level” when the logic probe is not connected to the instrument.
• For the specifications of the logic probe, refer to Section 15.23 “Logic Input Module.”
• The display for the 32-bit extended logic input is turned OFF as default. For turning ON/OFF the
display, see 5.1 “Turning Channels ON/OFF.”
