Condition Errors 801 to 899, Temperature
This series of errors corresponds to the bits in the 
STATus:QUEStionable:TEMPerature register. The second column in the 
table shows the corresponding bit in that register.
An event with the error number shown in the table means the condition has 
been detected. When the condition is cleared, an event with the error number 
plus 1000 is generated. These error numbers can be viewed in the Show Errors 
screen, along with the DETECTED and CLEARED indicators.
For example, error 801 indicates that the Ref Osc Oven Cold condition has 
been detected; error 1801 indicates that condition has been cleared.
This register is summarized as bit 4 of the STATus:QUEStionable register, as 
described in the section “Condition Errors 601 to 699, Error Summaries” on 
page 133.
