Comments

•

If a parameter is left off, then all the historical data for all parameters of that
command is erased. For example, if the <blower> parameter is left off of the

HIST:RES:BLOW

command, then ALL of the BLOWer historical data is

erased.

•

These commands are not allowed while the mainframe’s power is off.

Error Conditions

The following table lists the most common error conditions and causes. Error
numbers and corresponding messages can be found using

SYSTem:ERRor?

query.

Reset Condition

A *RST has no effect on the HISTory subsystem.

Number

Message

Probable Cause

-221

“Settings Conflict”

The mainframe’s power is off.

-224

“Illegal Parameter”

The parameter was not correct.

-311

“Memory error”

The historical data’s memory is not available.
