Using the demonstrator box
The optional demonstrator box can be used to test and demonstrate all functionalities of
the device. Because the pulse level and frequency can be adjusted, a wide range of
measurement scenarios can be simulated, which is why the demonstrator box is
outstandingly suited for in-house product training sessions.
The box can be switched on and off again by briefly pressing the
button. The LED
that lights up in red on the button signalises that it is ready for operation. If the LED does
not light up, this indicates that the battery is weak. In this case, the 4 x AA batteries in
the battery compartment on the bottom of the box must be replaced.
The magnets affixed to the bottom allow the box to be conveniently attached to a
metallic surface (e.g. a substation) for demonstration purposes.
The box starts operating directly after being switched on, and generates partial
discharge-like pulses. The level and frequency of the pulses, as well as the type of
decoupling, are based on the current settings, which can be adjusted as following using
the buttons on the front panel:
Button Setting
Selection of operating mode
Pressing this button repeatedly activates the available operating modes in
succession. The respective operating mode that is active is indicated by a
green LED. The selected operating mode also directly determines the type of
signal decoupling (see next page).
Adjustment of the pulse level
Pressing this button repeatedly activates the available settings in succession.
The respective setting that is active is indicated by the LED that lights up
above the button. The following selection options are available:
Low
Low level, which should induce measured values that are
uncritical for the thresholds preset by default (green)
Moderate
Moderate level, which should induce measured values that are
only slightly critical for the thresholds preset by default (yellow)
High
High level, which should induce measured values that are critical
for the thresholds preset by default (red)
Random
Level that changes every second
