Voltage / Contact Closure

The first key in the 4-key bank selects between voltage inputs or contact closures for

the discrete controls. More information on these inputs may be found in the section

entitled Rear Panel Connectors. For contact closure mode, set this key to the ON

position.

Restore Factory Defaults

Be sure to return this

key to the ON position

once the defaults

have been restored.

Failing to do so will

result in the DVM

restoring the defaults

every time it powers

on.

Setting the second key in the 4-key bank causes the DVM to reset all stored settings to

the factory defaults. These settings include the video configuration, password, network

address, and any other non-volatile settings stored on the DVM. Once you switch the

key to the OFF position, it only takes a moment to reset the defaults.

NTSC / PAL

The third key in the 4-key bank determines whether the DVM’s output format is PAL

or NTSC. When the key is ON, the DVM will output NTSC. When the key is OFF, the

DVM will output PAL.
