Frequently Asked Questions - DRC 1 PCE Instruments
How do I calibrate the DRC 1 refractometer?
Use distilled water or a standard calibration solution. Place a few drops on the prism, press the CAL button, and wait for the reading to stabilize. The device will automatically calibrate to zero (or the standard value).
What is the measurement range of the DRC 1?
The refractive index range is 1.3300 to 1.5000 nD, and the Brix range is 0.0 to 95.0%.
How do I clean the prism?
Gently wipe the prism with a soft, lint-free cloth dampened with distilled water. Avoid using abrasive materials or solvents, as they can scratch the prism.
What type of batteries does the DRC 1 use?
It uses two 1.5V AAA batteries. Alkaline batteries are recommended for longer life.
Does the device have automatic temperature compensation?
Yes, the DRC 1 features automatic temperature compensation (ATC) for measurements between 10°C and 40°C.
Can I measure hot liquids?
The device is designed for liquids at room temperature. For best accuracy, let the sample cool to within the ATC range (10-40°C) before measuring.
What does the 'LO' or 'HI' error mean?
'LO' indicates the measurement is below the minimum range; 'HI' indicates it is above the maximum. Dilute or concentrate the sample appropriately.
Is the refractometer waterproof?
The housing is rated IP65, meaning it is dust-tight and protected against low-pressure water jets. Do not immerse it in water.
How often should I replace the batteries?
Battery life depends on usage. Replace them when the display shows a low battery icon or the device fails to power on. Typically, batteries last for about 5000 measurements.
Where can I find replacement parts or get repairs?
Contact PCE Instruments or an authorized service center. Spare parts such as batteries and calibration standards are available from the manufacturer's website.
