Calibration Hints

Nominal Stability vs. Full Stability

To meet the criteria for a valid calibration point, the change (delta) in probe response is monitored over time. The controller is looking for the calibration solution temperature and the probe readings to settle over a specific time period. The criteria for Full Stability are designed to meet the published specifications. The criteria for Nominal Stability are designed to shorten the calibration time when an approximate calibration is acceptable.

Factory Recalibration

Proper maintenance can improve your results and extend the life of the instrument.

l RDO PRO and Aqua TROLL 400 instruments use the RDO Classic Sensor cap

that must be replaced annually. When this cap has expired, the exclamation icon appears on screen.

l RDO PRO-X Probes use RDO-X Sensor caps that typically last 2 years. If the

RDO-X Sensor cap has exceeded its recommended service period, or if the cap has sustained significant abrasion The Service Needed icon appears on screen.

Calibrating Conductivity

The Aqua TROLL 200 Instrument’s factory calibration with NIST-traceable standards provides a high degree of linearity across the entire operating range of 5 to 100,000 μS/cm. The Aqua TROLL 200 is capable of meeting its published specifications without requiring additional calibration by the user, as most commercially available standards can introduce a larger potential measurement error than the instrument’s initial factory calibration.

A user calibration is only recommended if you must conform to a standard operating procedure or if the cell has undergone physical change (e.g., deposits on conductivity cell walls that cannot be removed; physical damage to conductivity cell walls).

1. If you opt to calibrate the Aqua TROLL conductivity cell, refer to the calibration procedure in the Aqua TROLL Operator’s Manual for laboratory setup instructions.

2. From the Con TROLL PRO Main menu, select Calibrate, then Aqua TROLL 200 (or

100), then Conductivity.

3. Use the arrow keys to enter the standard value. Select Enter.

4. You will see the Calibration Beginning icon next to the μS/cm value. When the calibration reaches stability, choose Stable to accept the value or Cancel to return to the pre-existing calibration.

Zeroing the Pressure Sensor

Aqua TROLL 200 has been factory calibrated with NIST standards to a greater degree of accuracy than can be achieved in nearly any alternate setting.

The pressure sensor in an Aqua TROLL 200 can be “zeroed” in air, but should never be “zeroed” in water. In-Situ Inc. does not recommend zeroing the pressure sensor.

Setting a Level Reference

1. From the main screen, select Menu, Calibrate.

2. Select the Aqua TROLL 200 Instrument.

3. Select Level Reference, and use the arrow keys to enter the level reference value, and Press Enter.

Factory Recalibration

Proper maintenance can improve your results and extend the life of the instrument. When your instrument is overdue for a factory recalibration, the Service Needed icon will appear on the display.

l Factory recalibration of the Aqua TROLL Instruments should be performed every

12 to 18 months.
