Operating Instructions
PROFITEST H+E TECH
Phases and Phase Sequence
The symbols for the phases (see page 7) indicate whether or not phases L1, L2 and L3 are switched
on. The respective symbols appear when the phases are switched on. As soon as all 3 phases are
switched on, the direction of phase rotation is displayed (clockwise or counterclockwise).
Operating the Inline Tester with the Rotary Switches
The rotary switches currently have no function (except for switching display illumination back on).
They're included in order to be able to add menu driven operation by means of future product
updates.
Battery Display
Adequate battery voltage is imperative for testing the PWM signal. For this reason the inline tester
is equipped with a simple battery voltage display.
The symbol indicates whether or not battery voltage is adequate for proper diagnosis.
As soon as "battery depleted" is indicated (see also page 9), diagnosis is no longer possible.
"Battery full" is indicated when the power pack is connected.
USB Port
The USB port is used to install firmware updates and (depending on software version) to transmit
diagnostics results to a connected PC.
Warning!
Danger!
The USB port may not be connected to a PC or a notebook while a charging point is being
diagnosed!
Language Selection
Upon shipment from the factory, the user interface language of the inline tester is set to German.
Additional languages are also available. The device must be switched off in order to select a
different language.
In order to select a language, press and hold the escape button (2). Then simultaneously press and
hold the on button (4). The currently selected language is then indicated at the display (5). The
desired language can then be selected by turning the rotary mode selector switch (1) and
acknowledged by pressing the OK button (1). The inline tester is then restarted automatically with
the selected language.
The selected language is retained until a different language is once again selected.
