2. Deployment of S1100 pH Sensor

  1. Using the Abrasion Block to abrade the surface of the installed transducer as shown in Section 4.
  2. If in controlled interface mode please refer to
  3. If in autonomous mode attach the S1100 to the Battery Pack via the male/female SubConn cable and connectors (Pin 1 +V, Pin 4 GND). Connect the male/female at both ends of the cable and fasten the red sleeve.
  1. Once connected the S1100 will emit a ‘BEEP’ as feedback to confirm power supply.
    ** The user has 4 minutes to place the sensor in the water before it starts to record. At the end of this period the unit will beep again to provide a 15 sec. warning, after which it will double beep and scanning will commence.
    NOTE: If the sensor continues to beep during the 4 minute deployment time, please contact your representative at ANB Sensors.
  2. The array will scan at the preprogrammed rate until removed from the water.
  3. Once removed from the water, disconnect the Battery Pack and dry both completely and store safely.

3. Disconnecting from Power

  1. Simply unscrew the red sleeve on the cable and separate the male/female connectors.
  1. Reattach the SubConn protector to avoid any damage to pins.
  2. Ensure sensor is completely dry prior to storage.

4. Abrading Transducer

See video at

  • Only abrade the transducer once housed in the S1100 body.
  • Abrade the top surface of the transducer – the higher part with 14 black dots – using the abrasion tools in the Sensor Case.
  • Be cautious to ensure the abrasion block remains horizontal to the surface.

5. Removing the Transducer

  • Only remove the transducer if informed to do so by the program on TerraTerm.
  • The software will inform you to do this at one of two times: after data collection, or in the pre-deployment scan check.

Always ensure the sensor is dry before removing the transducer

  1. Using the spanner unscrew the three large bolts in the titanium plate until they begin to spin freely.
  2. Pull on the titanium plate to remove the array from the body as illustrated below.
  1. Using the supplied towel dry the cavity formed by the missing transducer.

6. Replacing the Transducer

Important note: the transducer can only be inserted in one orientation – if solid resistance is felt in the early stage ensure rotation is correct.

  1. Take the replacement transducer complete with plate, bolts, and nuts from the S1100 case or from a newly ordered part.
  2. To ensure you always possess a working transducer we recommend you purchase a new spare transducer at this point as they can have up to 8-week lead times.
  3. Apply silicone grease to the perimeter of the O-rings ensuring a thin and even covering.
  4. Using the three large bolts as a guide locate the correct rotation.
  5. If correct location is found the transducer should freely fall into the cavity until the lower O-ring.
  6. With minimal force, press the transducer in until the bolts contact the S1100 body.
  7. Using the provided 8mm spanner tighten the bolts until the transducer is flush with the S1100 body. Each bolt should be tightened incrementally.
  8. If the transducer is not flush with the body, you will not get any data and may damage the lifetime of the array.
