Chapter 5 Error Messages

Execution Errors

-151

Invalid string data

 

An invalid character string was received. Check to see if you have

 

enclosed the character string in single or double quotes and that the

 

string contains valid ASCII characters. Example: DISP:TEXT ’ON

 

(the ending quote is missing).

-158

String data not allowed

 

A character string was received but is not allowed for the command.

 

Check the list of parameters to verify that you have used a valid

 

parameter type. Example: CALC:STAT ’ON’

-160 to

-168

Block data errors

 

 

 

 

The multimeter does not accept block data.

 

-170

to

-178

Expression errors

 

 

 

 

The multimeter does not accept mathematical expressions.

 

-211

 

 

Trigger ignored

 

 

 

 

A Group Execute Trigger (GET) or *TRG was received but the trigger

 

 

 

 

was ignored. Make sure the multimeter is in the “wait-for-trigger” state

 

 

 

 

before issuing a trigger, and make sure the correct trigger source is selected.

 

 

 

 

 

-213

 

 

Init ignored

 

 

 

 

An INITiate command was received but could not be executed because

5

 

 

 

a measurement was already in progress. Send a device clear to halt a

 

 

 

measurement in progress and place the multimeter in the “idle” state.

 

 

 

 

-214

 

 

Trigger deadlock

 

 

 

 

A trigger deadlock occurs when the trigger source is BUS and a READ?

 

 

 

 

command is received.
