5-12 Rel, Math, Ratio, Channel Average, dB Model 2700 Multimeter/Switch System User’s Manual
Basic operation
NOTE If using switching module inputs, make sure the front panel INPUTS switch is set
to the REAR position (in). If using the front panel inputs, the switch must be in
the FRONT position (out).
1. Configure and enable the mX+b, percent, or reciprocal (1/X) math function as
previously explained.
2. Select the desired measurement function.
3. Apply the signal to be measured to a switching channel input or to the front panel
inputs.
NOTE For the Model 7700 switching module, channels 21 and 22 are available for DCI
and ACI. Channels 1 through 20 are available for all other functions.
4. If using a switching module (REAR inputs selected), use the  or  key to select
(close) the input channel. If using the front panel inputs (FRONT inputs selected),
it does not matter if a switching channel is closed. The result of the math
calculation will be displayed.
Scanning
When a simple scan is configured, the present math calculation will apply to all channels
in the scan. When an advanced scan is configured, each channel can have its own unique
math setup. Details to configure and run a scan are provided in
Section 7.
For remote programming, the <clist> parameter is used to configure channels for a scan.
