To ensure safe operation of the equipment and eliminate the danger of serious injury due to short-circuits
(arcing), the following safety precautions must be observed.
Damages resulting from failure to observe these safety precautions are exempt from any legal claims
whatever.
•
prior to connection of the equipment to the mains outlet, check that the available mains voltage
corresponds to the voltage setting of the equipment.
•
connect the mains plug of the equipment only to a mains outlet with earth connection.
•
do not place the equipment on damp or wet surfaces.
•
do not subject the equipment to direct sunlight or extreme temperatures.
•
do not subject the equipment to extreme humidity or dampness.
•
replace a defective fuse only with a fuse of the original rating. Never short-circuit fuse or fuse housing.
•
do not exceed the maximum permissible input ratings.
•
conduct measuring works only in dry clothing and in rubber shoes i.e. on isolating mats.
•
comply with the warning labels and other info on the equipment.
•
check test leads and probes for faulty insulation or bare wires before connection to the equipment.
•
disconnect test leads or probe from the measuring circuit before switching modes or functions.
•
do not cover the ventilation slots of the cabinet to ensure that the air is able to circulate freely inside.
•
do not insert metal objects into the equipment by way of the ventilation slots.
•
do not place water-filled containers on the equipment (danger of short-circuit in case of knockover of the
container).
•
do not operate the equipment near strong magnetic fields (motors, transformers etc.)
•
do not subject the equipment to shocks or strong vibrations.
•
keep hot soldering irons or guns away from the equipment.
•
allow the equipment to stabilize at room temperature before taking up measurement (important for exact
measurements)
•
do not modify the equipment in any way.
•
do not place the equipment face-down on any table or work bench to prevent damaging the controls at
the front.
•
opening the equipment and service- and repair work must only be performed by qualified service
personnel. Repair work should only be performed in the presence of a second person trained to
administer first aid, if needed.
Cleaning the cabinet
Prior to cleaning the cabinet, withdraw the mains plug from the power outlet. Clean only with a damp, soft
cloth and a commercially available mild household cleanser. Ensure that no water gets inside the equipment
to prevent possible shorts and damage to the equipment.

(a) Probe (b) PROBE compensation by Correction Square-Wave Abb. 2.2 Probe compensation 2.2.2 Signal Connections There are three methods of connecting an oscilloscope to the signal you wish to observe. They are: a simple wire lead, coaxial cable, and scope probes. A simple lead wire may be sufficient when the signal level is high and the source impedance low (such as TTL circuitry), but is not often used. -
Page 12: Single-Trace Operation
Single-trace operation with single timebase and internal triggering is the most elementary operating mode of the PeakTech 2020 GN or PeakTech 2030 KT. Use this mode when you wish to observe only a single signal, and not be disturbed by other traces on the CRT. Since this is fundamentally a two-channel instrument, you have a choice from your single channel. -
Page 13: Dual-Trace Operation
2.2.4 Dual-trace operation Dual-trace operation is the major operating mode of the PeakTech 2020 GN and PeakTech 2030 KT. The setup for dual-trace operation is identical to that of 2.3.2 Single-trace operation with the following exceptions: Set the V MODE switch (5) to either DUAL. Select ALT for relatively high frequency signals (A TIME/DIV switch set to 0.5 ms or faster). -

Trigger Mode Selection: When the NORM trigger mode is selected, the CRT beam is not swept horizontally across the face o the CRT until a sample of the signal being observed, or another signal harmonically related to it, triggers the... - Page 15 Triggerpoint selection The SLOPE switch determines whether the sweep will on a positive-going or negative-going transition of the trigger signal (See fig. 2-4). Always select the steepest and most stable slope or edge. For example, small changes in the amplitude of the sawtooth shown in Figure 2-4 a will cause jittering if the timebase is triggered on the positive (ramp) slope, but have no effect if triggering occurs on the negative slope (a fast-fall edge).
