Product(s): METRABUS MTHERM-20 MTHERM-16 Question: Does it matter where I place the MTHERM Card Answer :Because both Versions of the MTHERM Card draw relatively large currents from the +5 Volt Power supply, either MTHERM card should be positioned close to the 5 V source.In situations where this is inconvenient, users should consider using a customized heavy duty cable to deliver quality 5 Volt power to the board!    Copyright 2003, Keithley Instruments, Inc.
