:ERRor?

1004,EEROM data invalid

Corruption has been detected in the EEROM; it needs to be replaced, or, if brand new, it needs to have MEM:SAVE executed once.

1006,Channel timeout <17 hex digits>

This error is generated when a relay apparently fails to switch, based on the detected state of the sense lines. The 17 hex digits indicate which card and which of the 32 channels experienced failures just as for error 1001. Each channel has two associated bits; the leftmost indicates that the error was detected on the CLOSED side of the relay; the rightmost that the error was detected on the OPEN side. A failure is indicated with a 1.

❍

❍

❍

A Channel timeout without an accompanying Sense error indicates that the sense lines were in a valid state, but it was the wrong state.

A Channel timeout with a Sense error indicates that both sense lines appeared to be at 0 V.

A Sense error without a Channel timeout means both sense lines appeared to be at 24 V.

1007,Label too long

A path or group label was more than 32 characters long.

1008,Nonexistent group

An attempt was made to use a group name which was not previously set up with a GROUP:NAME command.

1009,Group already exists

An attempt was made to name a group with a name already in use by another group.

1010,Nonexistent path

An attempt was made to use a path name which was not previously set up with a PATH:DEF command.

4000,Divide by Zero

4001,Float Overflow

4002,Float Underflow

4003,Logarithm Error

4004,Integer Overflow

4005,Square Root Error
