WARNING
Death or severe injury caused by high voltage or current possible
Using the DC current mode may be very dangerous. In this mode, it is not possible
to interrupt the circuit using a standard relay or a standard circuit breaker. Due to the
arc, contact clearances of up to 10 mm are required to switch off the current.
► Do not use a standard relay or a standard circuit breaker to interrupt the current in this
mode.
► Always use a switching device with a sufficient contact clearance of > 10 mm to
switch off the current or stop the current output on CT Analyzer.
For this measurement type, the CT-Quick card holds the following measurement quantities:
Table 10-2: Parameters for Advanced measurement type
Parameter Description
Output Output signal type AC or DC or output signal switched off.
Possible values: AC or DC or Off. Default: AC.
U/I Operating mode of the internal signal generator: voltage or current source.
Possible values: U (voltage) or I (current). Default: Voltage
Amplitude RMS voltage or current value of the output signal.
Possible values:
Mode "AC" and "Voltage": 0 to 40V
Mode "DC" and "Voltage": 0 to 120V
Mode "AC" and "Current": 0 to 5A
Mode "DC" and "Current": 0 to 10A
Default: 1.00V or 1.00A.
f Frequency of the output signal. Only available for AC voltage or current output.
Possible values: Any value between 5.0 and 400.0Hz or soft keys 16.7Hz, 50Hz,
60Hz or 400Hz.
Default: 50Hz
Measurement Measurement mode.
Mode
Possible values: DC, RMS or f-sel. filter. Default: RMS
DC measurement:
Measures the DC part of the signal only.
RMS measurement:
Performs a standard true RMS measurement of the signal.
Frequency selective measurement:
Allows high precision measurement of the fundamental wave of an applied signal. All
frequencies below and above the output frequency plus/minus the filter bandwidth are
suppressed by at least 110 dB. This measurement mode is deactivated for output
signal type DC.
