4.21-10 Section 4: Using the Model 9100: AC Harmonics Function - Operation
Final Width = 215mm
4.21.5.4 Low and High Voltage States
In the interests of safety, to avoid electric shock, the 9100 incorporates a high voltage
interlock system for both DC and AC Power functions. The interlock threshold voltage
can be chosen by the user. A default threshold value is set unless another is set by the user,
and the active threshold value is stored in non-volatile memory.
Refer to Section 4.4.5.4 for further details.
4.21.5.5 Reconfiguration of High Voltage State Thresholds
N.B. A password will be required for access when changing thresholds.
The High Voltage State thresholds have default values and change procedures as given
in Sections 4.4.5.4 and 4.4.5.5.
4.21.6 Volt-Hertz Limits
4.21.6.1 Volt-Hertz Profile (Sinusoidal Waveshape)
The combination of voltage and frequency of the sinewave output signal is constrained
within the Volt-Hertz product envelope shown in Fig. 4.4.2. subject to further HF
limitations for Harmonics as stated in the specifications.
Any attempt to select a combination of voltage and frequency outside these constraints
will not be enabled. An audible warning will be given, accompanied by the screen
message: ‘Out of range’.
If the abortive attempt involves the use of Direct Editing. then a further message will be
placed into the active editing box.
