Model 2461 Interactive SourceMeter® Instrument Reference Manual Section 8: TSP command reference2461-901-01 A/November 2015 8-189DetailsOvervoltage protection restricts the maximum voltage level that the instrument can source. It is ineffect when either current or voltage is sourced.This protection is in effect for both positive and negative output voltages.When this attribute is used in a test sequence, it should be set before turning the source on.Even with the overvoltage protection set to the lowest value (2 V), never touch anythingconnected to the terminals of the Model 2461 when the output is on. Always assume that ahazardous voltage (greater than 30 VRMS) is present when the output is on. To preventdamage to the device under test or external circuitry, do not set the voltage source to levelsthat exceed the value that is set for overvoltage protection.Examplesmu.source.func = smu.FUNC_DC_VOLTAGEsmu.source.protect.level = smu.PROTECT_40VSets the maximum voltage limit of theinstrument to 40 V.Also seeOvervoltage protection (on page 2-121)smu.source.protect.trippedThis attribute indicates if the overvoltage source protection feature is active.Type TSP-Link accessible Affected by Where saved Default valueAttribute (R) Yes Not applicable Not applicable Not applicableUsagevalue = smu.source.protect.trippedvalue Overvoltage protection not active: smu.OFFOvervoltage protection active: smu.ONDetailsWhen overvoltage protection is active, the instrument restricts the maximum voltage level that theinstrument can source.Exampleprint(smu.source.protect.tripped) If overvoltage protection is active, the outputis:smu.ONAlso seeOvervoltage protection (on page 2-121)smu.source.protect.level (on page 8-188)
