During base code download, three high-high beeps sound when any errors occur. (The unit resets
and then the two high-high beeps mentioned in the previous bullet sound.)
Error Codes
In almost all cases, an error result causes the unit to sound the “low tone” three times and to illuminate the
red LED three times. When this happens, send the request for status message and then observe the “error”
code of the list returned. The “error” code will be one of the values in the table below.
Error
Code Error Cause
0 This is normal. No corrective action is needed.
1 Invalid FASTMODE. An attempt to select fast sampling mode was made.
When in FASTMODE, only a single analog channel can be active.
This error number also displays if the FASTMODE selection is a value other
than 0 or 1.
2 FASTMODE ABORT. During FASTMODE, an attempt to communicate with
the LabPro was made while it was waiting for a trigger. As a result, sampling
was aborted.
5 The list being sent contains a number that is too large to be represented
internally. This can only happen when the list being sent contains an error.
6 The list being sent contains a non-integer number where only integers are
allowed. For example, command numbers must be integers and a command
of 3.5 will produce this error.
8 The list being sent contained too many numbers for proper conversion. In
general, no more than 32 numbers can be sent for some commands and no
more than 44 numbers for other commands.
9 The command number sent (first number of the list) did not specify a valid
command.
12 The channel selected for setup did not exist. Channel numbers must be 1-3,
11, 21, 31.
13 The operation selected for the channel being setup is invalid. For example,
sonic channels cannot be setup for a voltage probe.
14 An invalid value was selected for the post processing parameter. This must
be a number from 0 to 2.
16 An invalid equation on/off parameter was found. The equation on/off
parameter must be a 0 or a 1.
17 An invalid Frequency/Period selection parameter was found. This error
usually occurs when a second channel is selected for a measurement during
Frequency/Period measurements.
18 Multiple channels are not allowed to be selected at the same time for the
Digital/Sonic inputs. This error usually means that the sonic port and a
corresponding digital port have been selected.
22 Command 2 contains invalid data.
30 The filter type must be between 0 and 6 for NON-REALTIME data collection
