Archiver

How's the logic probe look like at the connecting end?
I've look around but only saw those tat hav a red n
black plug jacks at the connecting end. Used them b4
on those big troubleshooting board. How do I power
them up w/o the big board? Eg. Red jack to +ve of BATT
n Black to -ve of BATT? R there any types tat we
insert batteries into them n operate?

Thnks!

i change the ends to a red and black microclip then
you can clip them on the legs of ttl logic chips
usely the bottom left pin is ground and the upper
right pin is vcc or 5 volts but check the chip pinout
on the web good luck
