Test considerations
When performing the calibration verification procedures:
• Be sure to restore factory front-panel defaults. From the front panel, select the MENU key, select
Info/Manage, and select System Reset.
• Make sure that the test equipment is warmed up for the time recommended by the manufacturer
and is connected to the DMM6500 input/output terminals.
• Make sure that the correct DMM6500 terminals are selected with the TERMINALS FRONT/REAR
switch.
• Make sure the test equipment is set up for the proper function and range.
• Do not connect test equipment to the DMM6500 through a scanner, multiplexer, or other
switching equipment.
Figure 1: VARIABLE - WARNING
The front and rear terminals of the instrument are rated for connection to circuits rated
Measurement Category II up to 300 V, as described in International Electrotechnical
Commission (IEC) Standard IEC 60664. This range must not be exceeded. Do not connect the
instrument terminals to CAT III or CAT IV circuits. Connection of the instrument terminals to
circuits higher than CAT II can cause damage to the equipment and severe personal injury.
