GND Post

Provides access to chassis ground, which is also an earth ground as long as a standard
3-wire line cord is used. This is a protective conductor terminal to be used to achieve
chassis grounding requirements when the main connectors don't provide an earth
ground terminal. Use a minimum of 18 gauge wire to connect to this terminal.

Warm Up and Environmental Consideration

Operate the 6000 at an ambient temperature in the range of 0 to +40°C. Storage
temperatures should be in the range of -20 to +60°C. To achieve rated accuracy, let
the 6000 warm up for 1 hour. For greatest accuracy, recalibrate when ambient
temperature changes more than a few degrees.
System Operation
Do not exceed 250 VAC on the line input.
Do not operate with a line voltage that is not within ±10%
of the line setting. Too low of an input voltage may cause
excessive ripple on the DC supplies. Too high of an input
voltage will cause excessive heating.
Operating above +40°C can cause excessive heating and
possible component failures.
