To use the loop power converter module with a HMP60 or HMP110
series probe, make sure that:
- The probe is in the analog output mode
- The desired quantity must be on channel 1
- Channel 1 is scaled to 0 ... 2.5 V
When using the loop power converter module, power the module with
8 ... 28 VDC. The operating voltage for the probe (5 VDC) is delivered
by the module.
