4.4.2 KepcoDCPwr Measure [MSR].vi
This VI takes a measurement of the output signal and returns the measured value (see Figure
4-4.
FIGURE 4-4. KepcoDCPwr Measure [MSR].vi CONTROL PANEL
This VI has the standard inputs of all of the functions of the LabView G Driver. It also has three
orange inputs at the top of the VI (Virtual Resistance, Virtual Current, Virtual Voltage). These
inputs are used in simulation. They do not need to be connected, but provide the ability to verify
the operation without using the power supply. These simulation inputs are only used when
error in is true (indicating an error has occurred).
Figure 4-5 is a block diagram which shows the method used by the VI to perform the simulated
current measurement. The query MEAS:CURR? is transmitted to the power supply which
replies with the current measurement.
TABLE 4-4. KepcoDCPwr Measure [MSR].vi INPUT/OUTPUT DESCRIPTIONS
DESCRIPTION SYMBOL
channel name - ("1") Passes the name of the channel on which to configure the voltage level. It is not required
for most supplies and is provided for compatibility.
Valid Channel Names: 1
Default Value: "1"
error in (no error) - The error in cluster can accept error information wired from VI’s previously called. Use this
information to decide if any functionality should be bypassed in the event of errors from other VI’s. The pop-up
option Explain Error (or Explain Warning) gives more information about the error displayed (see Table 4-3).
VISA Session - The ViSession handle is obtained from the KepcoDCPwr Init or KepcoDCPwr InitWithOptions
function. The handle identifies a particular instrument session. Default Value: None
Model Out - The Model Out handle is obtained from the KepcoDCPwr Init or KepcoDCPwr InitWithOptions func-
tion. The handle identifies a particular instrument. Default Value: None
channel name out - ("") Passes the name of the channel on which to configure the OVP limit.
Valid Channel Names: 1; Default Value: ""
