Measurement Function

As the Product powers on, it will enter the measurement screen by default, as shown in
The Product provides DCV and ACR measurement values. The Product measure through the internal
or external Multiplexer Card if any channel is selected; and the Product measure through the front
panel terminals if no channel is selected.
For measurement using the front panel terminals, FUNC button can be used to switch among
" ACR+DCV, "ACR", and "DCV". If any channel is selected, "ACR+DCV", Enclosure Potential
Contact Check", "Positive to Enclosure Voltage" and "Negative to Enclosure Voltage"
measurement functions can be selected, and the FUNC button on the front panel will be disabled.
By default, the measurement function is ACR+DCV, the DCV and ACR measurement values are
provided (with other function setting, only ACR OR DCV is provided). The DCV value is displayed at
the upper of the main display area, and the ACR values is at the lower.

DCV

DCV measurement function features the following:

User configurable input impedance: the default setting is 10 MΩ, and it can be changed to High Z
(>10 GΩ). See the section

Range: 10 V and cannot be changed. Range information won't be displayed on the screen.

The readings that can be displayed are -11.000000 V to 11.000000 V(BT5320/BT5321) or -
11.00000 V 11.00000(BT5310/BT5311). "- OL" is displayed if the measured value <-11 V; "+
OL" is displayed if the measured value > 11 V; "----" is displayed if the measured is <-12 V
or >12 V.

ACR

For ACR function, only 4-wire connection is supported. The default is AUTO Range mode. User can
configure measurement range.
