3. MAXIMUM OUTPUT VOLTAGE The Model 5070 provides the ability to limit the maximum test voltage to a value you specify from 40 to 5100 volts When programmed the instrument will not gen erate a higher voltage to conduct the test even if the switch position indicates a higher voltage For example if you set the maximum voltage to 1250 volts and you place the rotary switch in the 5000 volt position and start a test the Model 5070 will only output 1250 volts Range 40 to 5100V 24 Megohmmeter Model 5070 SET DEFAULT PARAMETER This function allows you to reset all the user programmable functions back to the factory defaults CLEAR MEMORY The clear memory function allows you to selectively erase individual tests or all tests from the internal memory of the instrument A warning will appear first to ensure that you don t do this by accident V DISTURBANCE V OUTPUT see Appendix C This ratio defines the maximum allowable disturbance voltage depending on the selected measurement voltage If the V Disturbance exceeds the value of the ratio the instrument stops the test in process If the voltage exceeding the ratio is pres ent at the device under test before the test is started a test will not be allowed to start Three programmable values are 3 10 and 20 of the measurement voltage The default is 396 Example If a test is to be performed at 1000V and the V Disturbance V Output is set at 10 the presence of
