Hach GS1140 Manual Del Usuario página 8

Do not point the measuring end of the sensor up or damage to the sensor can occur (e.g., during storage,
transport, calibration, installation and operation).
Keep the sensor at 0 to 40 °C (32 to 104 °F) or damage to the sensor will occur.
The GS1440 and GS2440EX sensors continuously measure the hydrogen sulfide (H
concentration in liquids and air. Refer to
The sensor is used with a device that supplies 4–20 mA loop power to the sensor and receives the
sensor measurements as a 4–20 mA analog signal or RS-232 digital signal.
The GS1440 is made for use in non-hazardous locations. The GS2440EX is made for use in
hazardous locations.

Status
The 4–20 mA analog output represents 0–5 mg/L (liquids).
The 4–20 mA analog output represents 0–1000 ppm (air).
The sensor is in calibration/configuration mode.
Temporary (with calibration cap attached): Calibration was not successful.
Continuous (without calibration cap attached): There is a problem with the sensor.
