PLH Series DC Power Supplies: Precision Metering

Precision Metering - clear and unambiguous "at a glance"
High accuracy, four digit, fixed-resolution meters
The PLH series uses four digit meters for both voltage and current.The fixed resolution ensures that there are no sudden and confusing changes in the reading. Some other power supplies use 3 digit meters which autorange at 1999 counts.
Not only does this reduce resolution, but it also changes the position of the most significant digit. When glancing at the display this could lead to mis-reading of the value by a factor of ten.
