23Subject to change without notice1 Hz – 1 MHzThese AC square wave signals can be used for probeadjustment and judgement of the frequency response. Asthe frequency and the pulse duty factor accuracy are notimportant for such purposes, these values are not specifiedand are therefore relatively inaccurate.Dependent on TBThe square wave signal’s pulse duty factor differs widely inmost settings from 1:1. In time deflection ranges from500 ms/div to 1μs/div. the period length and the time deflectioncoefficient are equal; this allows you to check the time baseaccuracy. The smallest period length is 1 μs (1 MHz) andconsequently time coefficients <1μs/div do not change it.[36] 0.2 Vpp Concentric socketThis socket serves as the output for the signals describedunder item CAL. SEL. [35]. The output impedance is approx.MAIN MENUThe instrument software contains several menus. The followingmenus, submenus and menu items are available:1. ADJUSTMENT contains the submenus:1.1 AUTO ADJUSTMENT with the menu items1.1.1 SWEEP START POSITION1.1.2 Y AMP1.1.3 TRIGGER AMP1.1.4 X MAG POS1.1.5 CT X POSCalling one of these menu items requires that no signal is appliedon any input. For further information note „Adjustments“.1.2 MANUAL ADJUSTMENT contains menu items that areonly accessible for HAMEG workshops.2. SETUP & INFO contains the submenus:Main Menue50 Ohm. For high impedance loads (Oscilloscope approx.1 M Ohm, Digital Voltmeter approx. 10 MOhm) the outputvoltage is either 0.2 Volt DC or 0.2 V pp (AC, square wave).Under “First Time Operation” section “Probe compensationand use” the most important applications of this signal canbe found.[37] CT – Pushbutton and 4mm banana jackBriefly pressing the pushbutton switches the instrumentover from oscilloscope to “Component Tester” mode andvice versa.This mode is indicated by the READOUT which displays”Component Tester”.One test lead is connected to the CT socket. The second testlead uses the ground socket [27].Please note ”ComponentTester”.The maximum test voltage is approx. 20 V pp under opencircuit conditions, while the max. test current under shortcircuit condition is approx. 20 mA pp.Briefly pressing the CT-pushbutton switches back to theprevious oscilloscope operating conditions.2.1 MISCELLANEOUSActive functions are indicated by „x“. SET switches overfrom active to inactive and vice versa.2.1.1 CONTROL BEEP. Acoustic signal confirms error freeoperation.2.1.2 ERROR BEEP. Sounds in case of operating error.2.1.3 QUICK START. Reduces the waiting time after POWERON, as neither the HAMEG logo nor the check andinitialisation are displayed.2.2 FACTORYSubmenus are available only for HAMEG authorized serviceworkshops2.3 INFODisplays information regarding the instrument’s hardwareand software.CTGLUE SETONOFFCAL.SEL.UNIT0.2 Vpp SELECT SOURCEC U R S O RMEASURE MAIN MENUREADOUT37 3637 35 34 33 32 31
