Before using the output function be sure to press OUTPUT confirming that either REC or annunciator is Output is made even when both annunciators are off but the power will be automatically off in approximately 10 minutes since the auto power off function is activated If OUTPUT is pressed in an auto range AUTO the current range is set as the key is pressed AUTO annunciator is turned off Errors may occur or output values unless auto zero adjustment is done in DC A mode The zero cancel function does not affect output Thus voltage would be generated because of an ambient temperature even if there is no input Chapter 2 Measurement Procedure 0 0 0 0 0 0 23 outputs analog outputs The output response time during a f s input differs between rise 0 to 90 about 250 ms and fall 100 to 10 about 500 ms Figs 2 and 3 As the measured value is small to the range response time becomes long Changes of counter updating rate peak measurement frequency measurement recording and data holding are possible when generating current measurement output But output will be changed during mode shift range shift shift to voltage measurement mode or auto zero adjustment Use the optional 9094 OUTPUT CORD to connect the unit to a recorder For recorders use over 1 input impedance Low impedances wil
