Usage: 

Asynchronous command

SENSe:CURRent:RANGe:AUTO:DOWN:MINimum 

<arg0>

SENSe:CURRent:RANGe:AUTO:DOWN:MINimum? 

<arg0>

Sets or queries the smallest range that instrument autorange switch to.

Parameters for setting and query: 

<arg0>

Range: 

10 

µ

A  to  100 mA

*RST: 

1 mA

Example: 

SENS:CURR:RANG:AUTO:DOWN:MIN 1E-003

The instrument does not switch to a measurement range lower
than 1 mA range.

SENSe:CURRent:RANGe:AUTO:DOWN:THReshold 

<arg0>

Sets or queries the threshold duration for autorange in the underrange condition.

Parameters:

<arg0>

Range: 

µ

s  to  0.13 s

*RST: 

1.5 ms

Example: 

SENS:CURR:RANG:AUTO:DOWN:THR 0.001

The instrument does not switch to a lower measurement range if
the underrange condition is shorter than 0.001 seconds.

SENSe:CURRent:RANGe:AUTO:UP:APPRoach 

<arg0>

SENSe:CURRent:RANGe:AUTO:UP:APPRoach? 

<arg0>

Sets or queries how autorange handles an overrange condition.

Parameters for setting and query: 

<arg0>

DEFault | TOP | STEPwise

DEF

Default = TOP.

TOP

If overrange is detected, the measurement range switches to the
highest range. After which, the instrument switches to a lower
range if necessary.

STEP

Measurement range is switched to the next range step until the
overrange condition stops.
*RST: 

TOP

Example: 

SENS:CURR:RANG:AUTO:UP:APPR TOP

If overrange is detected, the measurement range switches to the
highest range. After which, the instrument switches to a lower
range if necessary.
