To Next PageTo Next PageWhy are the readings erratic on my Watts HF scientific CLX- XT Measuring Instruments?
Erratic readings on your Watts Measuring Instruments can be caused by: * Bubbles in the solution. To resolve this, install a bubble elimination chamber. * Debris in the flow. To resolve this, clean the T-strainer.
What to do if readings are lower than expected on Watts HF scientific CLX- XT?
If the readings on your Watts Measuring Instruments are lower than expected, it could be due to several reasons: 1. Condensate or a leaky measurement cuvette. Install a desiccant cartridge kit to fix this. 2. A dirty measurement cuvette. Clean or replace the cuvette. 3. Bad or expired reagents. Replace the reagents. 4. The buffer reagent is not being dispensed. Check the buffer lines and check valves.
What to do if lower display shows MA on Watts HF scientific CLX- XT?
If the lower display on your Watts Measuring Instruments shows 'MA', it indicates a 4-20 mA loop open. To solve this, check the wiring.
