The multimeter indicates an overload condition (input greater than the
selected range can measure) by displaying or storing:
±
9.900000E+037
for the measurement. For temperature measurements:
9.910000E+037
indicates an overload condition.
An overload sets the Device Dependent Error bit in the Standard Event
Status Register. However, the overload does not generate an error message.
Measurements can be displayed on the HP E1301A mainframe, returned to
the output buffer and entered into a computer, or stored in memory. This
section explains how a reading destination is selected.
The data formats available depend on the reading destination. Table 4-3
shows the data formats available for each reading destination.
