This eliminates the need to externally ground the input to establish a DC ground reference Pre charging To minimize surge currents in the circuit under test when using deflection factors of 50 mV Div through 1 mV Div and a test lead or 1X probe use the AC DC and GND pushbuttons to take advantate of the pre charging circuit incorporated in the unit The pre charging circuit permits charging the coupling capacitor to the DC source voltage when the AC and GND buttons are pressed in and also limits surge current to the coupling capacitor from the signal source The procedure for using this circuit is as follows a Before connecting the BA 18N to a signal containing a DC component push in the AC and GND buttons Then connect the input to the circuit under test b Wait about one second for the coupling capacitor to charge 2 3 Operating Instructions 5A 18N c Remove the ground from the coupling capacitor GND button out The display will remain on screen and the AC component can be measured in the usual manner Deflection Factor The amount of trace deflection produced by a signal is determined by the signal amplitude the attenuation factor if any of the probe the setting of the VOLTS DIV switch and the setting of the Variable control The deflec tion factors indicated by the VOLTS DIV switch are cali brated oniy when the Variable control is rotated fully clockwise into the detent CAL position The range of th
