Model 5030 SHARP Monitor Instruction Manual
Indicated in μg/m
[Measured value]:
mantissa and 2 characters exponent, each one with sign.
Mantissa: sign followed by 4 numerical characters. The decimal
point is located after the first two decimal characters and is not
transmitted. Exponent: sign followed by 2 numerical characters,
leading zeros are included in the transmission.
[Status]:
4 characters, operational and error status byte, each one being
represented by two characters, formed like the BCC: operating
status <SP> error status
[Serial no.]:
Number of manufacture to guarantee unique device identification
[SFKT]:
Special function, not used, six times the numerical character 0.
Note In the previous example, the indication is only in μg/m³ if the
transmitted variable is the Concentration. The user may select other
variables for transmission through the Geystec Protocol menu. The variables
which can be selected are:
Conc, Mass, Q-OP, Q-N, T1, T2, T4, RH, P1, P2, and P3
Significance of the operating status bits:
1. Standard: Operating and error status as described in the
"Troubleshooting" chapter.
2. Compatible with FH 62 I-N:
02 : Keyboard active
04 : Filter change
Significance of the error status bits:
01 : Air flow disturbed
02 : Breach or end of the filter tape
04 : Detector error
08: Heater error
10: Any error occurred
<ETX>[BCC1][BCC2] is replaced by <CR><LF>, if the data inquiry has
been terminated by <CR>.
