High Voltage SourceMeter Instrument Reference Manual Section 12:
2470-901-01 Rev. A / May 2019 12-81
Details
Overvoltage protection restricts the maximum voltage level that the instrument can source. It is in
effect 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 (20 V), never touch anything
connected to the terminals of the 2470 when the instrument is on. Always assume that a
hazardous voltage (greater than 30 V
RMS
) is present when the instrument is on. To prevent
damage to the device under test or external circuitry, do not set the voltage source to levels
that exceed the value that is set for overvoltage protection.
Example
SOUR:VOLT:PROT?
Set the voltage source protection to 40 V
and query the value. The output is:

Overvoltage protection (on page 4-34)
:SOURce[1]:<function>:PROTection[:LEVel]:TRIPped?
This command indicates if the overvoltage source protection feature is active.
Type Affected by Where saved Default value
Usage
:SOURce[1]:VOLTage:PROTection[:LEVel]:TRIPped?
Details
When overvoltage protection is active, the instrument restricts the maximum voltage level that the
instrument can source.
If the voltage source does not exceed the set limits, the return is 0. If the voltage source exceeds the
set limits, the return is 1.
Example
If overvoltage protection is active, the output is:
1
