The following applies to loggers with channels types bpr_00 up to bpr_07 types (loggers manufactured previously to november 2015, or under a special request). For the newer implementation of BPR channels, please refer to derived BPR channels implementation.
Usage
>> bpr <index> [ sensorsettling | integrationtime | serial | fullscale | paroscaldate | oversampling | U0 | Y1 | Y2 | Y3 | C1 | C2 | C3 | D1 | D2 | T1 | T2 | T3 | T4 | T5 ]
Security
Open, Unsafe for update (modifications not permitted while logging).Description
This command is specific to loggers with one or more BPR (Bottom Pressure Recorder) channels installed. It reports or sets information regarding a BPR channel specified by <index>; the <index> argument is the same as that used for the command channel. A channel can be identified as a BPR channel by its reported type:
<< channel <index> type = bpr_00 | bpr_01 | bpr_02 | bpr_03 | bpr_04 | bpr_05 | bpr_06 | bpr_07
Descriptions of the available parameters follow:
- sensorsettling is the sensor settling time, in milliseconds, before any measurement is made. It is greater than 10 ms and below 65000 ms.
- integrationtime is the integration time, in milliseconds, taken for one measurement. It is greater than 20 ms and below 172,800,000 ms (2 days).
- serial is the Paroscientific sensor serial number.
- fullscale is the range rating of the Paroscientific sensor. It is in meters.
- paroscaldate is the Paroscientific calibration date and must be given in <YYYYMMDD> format.
- oversampling is the number of readings averaged for each measurement; it should be between 1 and 128 inclusive.
- U0,Y1,Y2,Y3,C1,C2,C3,D1,D2,T1,T2,T3,T4,T5 are the calibration values of the sensor provided by Paroscientific, reported as floating point numbers using a format with a mantissa and exponent; for example 3.3910000e+003. When setting coefficients, any simple format compatible with floating point representation may be used; for example 11, 11.000 or 1.10e+1 would all be accepted.
Parameters may be read individually or in any combination, but setting more than 15 parameters at a time is not possible.
Examples
>> bpr 2
<< bpr 2 serial = 210, fullscale = 2000, U0 = 5.8, Y1 = -3954.4, Y2 = -10760.9, Y3 = .0, C1 = -29800.7, C2 = 1820.5, C3 = 106769.1, D1 = 0.0, D2 = 0.0, T1 = 30.0, T = 1.8, T3 = 65.9, T4 = 221.7, T5 = 0.0, paroscaldate = 20130115000000, integrationtime = 600, sensorsettling = 2500, oversampling = 64
>> bpr 3 sensorsettling=1000, integrationtime = 300
<< bpr 3 integrationtime = 300, sensorsettling = 1000
Errors
Error
E0105 command prohibited while logging
Parameters may not be modified while logging is in progress.
Error
E0107 expected argument missing
An argument expected by the logger was not given with the command; for example, there must always be an <index> argument, and if setting coefficients then all fields required must be supplied.
Error
E0108 invalid argument to command: '<invalid-argument>'
The supplied argument was not valid.
Error
E0501 item is not configured
There is a problem with the configuration of the specified channel; please contact RBR Ltd for help.
