Appendix A. CS110 Measurement
Status Codes
Status codes 1 through 3: Good Instrument Health.
status = 1, Good instrument health. ±250 mV measurement range only.
Return measured Efield value.
status = 2, Good instrument health. ±2500 mV measurement range used.
Return measured Efield value.
status = 3, Good instrument health. NAN returned for Efield because of
measurement over-range on the
±2500 mV measurement range.
No priority issues exist with status codes 1 through 3 since only 1 of these
“Good Instrument Health” codes can exist for a given measurement.
Status codes 4 through 6: Good measurement, after properly positioning
the shutter.
status = 4, Good instrument health. ±250 mV measurement range only.
Had to properly position shutter.
status = 5, Good instrument health. ±2500 mV measurement range used.
Had to properly position shutter.
status = 6, Good instrument health. NAN returned for Efield because of
measurement over-range on the
±2500 mV measurement range. Had to
properly position shutter.
Status code 4 through 6 indicate that the shutter was not properly positioned
upon commencing the measurement. The problem was recognized, corrected
and a valid measurement made. Status codes 4 through 6 are common upon
power up, or if the shutter has been touched or bumped since the last execution
of the CS110 instruction. Persisting status codes 4 through 6 indicate a problem
with parking the shutter that should be investigated.
Status codes 7 through 10: Datalogger warnings and errors.
status = 7, +5Vext low. Return measured Efield value.
status = 8, Datalogger skipped scan. Return measured Efield value.
status = 9, Input power < 9.6 V. Return measured Efield value.
status = 10, Datalogger watchdog reset. Return measured Efield value.
Status codes 7, through 10 increase in priority with 7 being the lowest and 10 the
highest of the warning and error codes. Status code 7 is a low priority error
message, as low +5Vext is a concern, but does not corrupt electric field
measurements. Status code 7 is overwritten by any other warning and error
code (i.e. status
≥ 7), including Leakage current exceeds compensation range.
Status codes 8 through 10 are the highest priority error messages returned by
the CS110, and will overwrite other lesser errors that occur simultaneously
during the CS110 instruction. Since only one status value can be returned from
a CS110 instruction, status 10 is given the highest priority, status 9 the second
highest, and 8 the third highest priority of CS110 status codes. Next in priority
are codes 16, 15, 14, 13, 12, and 11 followed by 7, 6, 5, 4, 3, 2 and 1.
