13 Direct Analog Test Probes (DATP00…DATP12)

• Input-only

• Connected directly from PPC to PLT

• DATP00…DATP06 are hooked up to the built-in DMM of the PLT-300A, for precise measurements at voltages up to 100V.

• DATP00…DATP06 can be switched to the MUX0 and MUX1 channels for shorting, impedance or voltage measurements

• DATP00…DATP12 are connected directly to ADCs, allowing differential voltage measurements, and voltage measurements against PLT system ground.
