How To Implement The Function Inspection; How To Implement The Probe Compensation - PeakTech 1190 Bedienungsanleitung

5. How to implement the Function Inspection

Make a fast function check to verify the normal operation of the instrument, according to the following steps:
1. Connect the Instrument to the Power and Push down the Power Switch Button.
The instrument carries out all self-check items and shows the prompt "Press any Key Enter system".
Press the "8 (UTILITY)" button to get access to the "FUNCTION" menu and push down F2 the menu
selection button to call out the function "Recall Factory". The default attenuation coefficient set value of
the probe in the menu is 10X,
2. Set the Switch in the Oscilloscope Probe as 10X and Connect the Oscilloscope with CH1 Channel.
Align the slot in the probe with the plug in the CH1 connector BNC, and then tighten the probe with
rotating it to the right side.
Connect the probe tip and the ground clamp to the connector of the probe compensator.
3. Press the "7(AUTOSET)" Button.
The square wave of 1 KHz frequency and 5V peak-peak value will be displayed in several seconds (see
Fig.4).
Check CH2 by repeating Step 2 and Step 3.

6. How to Implement the Probe Compensation

When connect the probe with any input channel for the first time, make this adjustment to match the probe with
the input channel. The probe which is not compensated or presents a compensation deviation will result in the
measuring error or mistake. For adjusting the probe compensation, please carry out the following steps:
1. Set the attenuation coefficient of the probe in the menu as 10X and that of the switch in the probe as 10X,
and connect the oscilloscope probe with the CH1 channel. If a probe hook tip is used, ensure that it keeps
in close touch with the probe. Connect the probe tip with the signal connector of the probe compensator
and connect the reference wire clamp with the ground wire connector of the probe connector, and then
press the button "7(AUTOSET)".
