## Phidget Frequency Counter.lvlib:FrequencyCounterStart.vi

Opens and initializes a Phidget Frequency Counter

| FrequencyCutoff Frequency at which 0 Hz is assumed.

| error in (no error) error in can accept error information wired from VIs previously called.

| status status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred. Right-click the error in control on the front panel and select Explain Error or Explain Warning from the shortcut menu for more information about the error.

| code code is the error or warning code. Right-click the error in control on the front panel and select Explain Error or Explain Warning from the shortcut menu for more information about the error.

| source source describes the origin of the error or warning. Right-click the error in control on the front panel and select Explain Error or Explain Warning from the shortcut menu for more information about the error.
