If the signal frequency is not known, there are two other methods for correct time coefficient setting.

Thus any intermediate value inside the 1 scale can be set. The timebase fine control knob is then out of operation. Correction of a few degrees is pos- sible by turning a potentiometer behind an opening on the front panel marked with TR using a small screw driver.

Battery-powered hk AC supply operated optional. Do not depress any further buttons. The condition for this is that no modifications have been made in the instrument. Using the 2 V CAL. The time resolution poses no problems. This must be set either to DC or to LF. The clear advantage over ordinary probes are field replaceable parts and the HF-compensation feature on the 1 0: Switch test signal coupling to AC or DC.

When using attenuators probes, even high internal imped- ance sources are only slightly loaded approx. I button may be used.

With the time axis expanded fold X-MAG. Amplitude measurement with Y fine control at right stop CAL. If they are depressed, the memory contents are retained until the mains voltage is switched off or fails. All operating modes, such as single- or dual-channel operation, add- or dif- ferential mode, X- and Y-expansion, X-Y operation, as well as the various trig- ger facilities are also available in storage operation.

When the instrument is assembled later, pay attention that the casing is seated behind the edge of the front molding lip on all hame. All four buttons out for mono mode. New storage is only possible on each channel when the relevant button is released out. Neither overshooting nor rounding off is allowable. Without a test signal applied, the base line is only vis- ible if this button is not pressed in the AT-position automa- tic triggering.

The leading edge should be as steep as possible but the top as straight as possible. The 1 MQ input resistance can equally serve as R here, so that only a suitable capacitor C needs to be connected in series. The current time sweep is inter- rupted. Adjusts vertical position of trace for Channel 1 and Channel II. The faster line pulses are then attenuated by a low pass filter to such an extent it is easily possible to trigger on the leading or trail- ing edge of the frame-synchronizing pulse using the level control.

For amplitude measurements, the variable control on the input attenuator switch yameg be in its calibrated position CAL.

The variable controls for amplitude and time base and the LEVEL knob can also be used for this adjustment – without influence on the result.

The test methods described in the test plan of this manual can be performed without great expenditure on measuring instru- ments. With AC coupling of low frequency signals, the attenuation is no longer independent of frequency, pulses can show pulse tilts.

Ml 2 Subject to change without notice Automatic triggering can be used both with internal and external via the socket TRIG. To obtain a well-triggered display in hameeg case, the assistance of the variable time control may be required.

DC-input coupling is therefore of quite special importance with a xlOO attenua- tion probe which usually has a voltage rating of max.
