3 Initial Start-Up
3.1 Start-Up of the Optional High-Voltage Module
3.1.1 Mounting the High-Voltage Module to the Basic Instrument
The HP or the HV high-voltage module must be mounted to the
PROFITEST 204+ test instrument before initial start-up.
When correctly mounted, reliable data exchange is assured
between the two devices by means of LED transmission (see
chapter 3.7.4, “Performing the Self-Test”).
The basic instrument and the high-voltage module must
both be disconnected from the mains and from the
measuring circuit prior to mounting.
➭ Close the lid of the basic instrument.
➭ Turn the basic instrument upside down. Place it onto a soft
surface in order to avoid scratching the lid.
➭ Pull the two rubber feet from the bottom of the basic
instrument behind which the through-holes are concealed.
➭ Position the high-voltage module such that the connector
terminals and cables from both devices are on the same side.
➭ Pull the two rubber feet from the bottom of the high-voltage
module behind which the through-holes are concealed.
➭ Set the four threaded rods into the through-holes (see sketch).
➭ Tighten the threaded rods with a screwdriver (4.5 mm).
➭ Insert the two previously removed rubber feet into the holes at
the high-voltage module.
