Device Current

With the Device Current function selected, the display will show the current draw of the

DUT. The Receptacle should be configured with HOT-CLOSED, NEUTRAL-CLOSED,

GROUND-CLOSED and POLARITY-FWD. Refer to the Specifications section for

current capacity and permitted duty cycle for this test mode.

Earth Resistance

With the Earth Resistance function selected, the display will show the resistance

between the Chassis Test lead and Receptacle Earth/Ground. This resistance is a

combination of the resistance within the DUT enclosure and the resistance of the

Earth/Ground Lead in the DUT power cord.

NOTE: This test has no meaning for equipment that does not use a grounded cord.

The test requires that the Chassis Test lead be plugged into the Chassis Connector.

The other end should be connected to a solid ground point on the DUT.

The display is in hundredths of Ω and will read to 19.99 Ω. Over-range shows as

“1_ _ _”.

Earth/Ground Leakage Current

With the Earth/Ground Leakage function selected and the Ground-Open, the display will

show the leakage current in the ground wire of the DUT.

NOTE: This test has no meaning for equipment that does not use a grounded cord.

Selecting this function automatically opens the connection to Earth/Ground and passes

any leakage current through a 1000 Ω load with either AAMI ES1-1993 or IEC 601

frequency compensation as selected by the Load Selection switch.

Enclosure Leakage

With the Enclosure function selected, the display will show the leakage current between

the Enclosure (Chassis) and Earth/Ground.

The test requires that the Chassis Test lead be plugged into the Chassis Connector.

The other end should be connected to a solid ground point on the DUT.

NOTE: If a non-conductive enclosure is used, a 200 cm

conductive foil pad should be

used. This foil is to be placed in close contact with the enclosure and connected to the

Chassis Test lead.

Any leakage current will flow through the Chassis Test lead and then through a 1000 Ω

load with either AAMI ES1-1993 or IEC 601 frequency compensation as selected by the

Load Selection switch.
