Ohaus CP series electronic balance maintenance
Common fault information and solutions
| Fault phenomenon | Possible cause | Solution |
| Unable to start | • No power | • Check connections and voltage |
| Weighing readings are not accurate | • There is no correct calibration balance • Unstable working environment | • Calibrate the balance • Shift the sky to a stable place of work |
| Cannot calibrate the balance | • Incorrect calibration method • Unstable working environment | • Calibrate the balance in the right way • Shift the sky to a stable place of work |
| Cannot change weighing mode | • Weighing mode is not activated | • Enter menu mode to activate weighing mode |
| Cannot change weighing unit | • The weighing unit is not activated | • Enter unit mode to activate the weighing unit |
| Err 5 | • Average weight is too small | • Add additional samples |
| Err 7.0 | • time out | |
| Err 8.1 | • There are heavy objects on the weighing pan before starting up | • Remove heavy objects and press the zero button |
| Err 8.2 | • Remove the weighing pan before turning it on | • Reinstall the weighing pan |
| Err 8.3 | • The weight on the weighing pan exceeds the maximum weighing value | • Remove heavy objects from the weighing pan |
| Err 8.4 | • Remove the weighing pan during weighing | • Reinstall the weighing pan |
| Err 9.5 | • Factory setting error | • Contact an authorized dealer |
| Err 9.8 | • Factory setting error | • Recalibrate the balance |
| REF Err | • The sample weighing value as a reference is too small | • Add extra samples |
| Error 53 | • EEPROM data error | • Contact an authorized dealer |
| LCWrEF | • When counting and percentage weighing are performed, the sample weighing value as a reference is too small to accurately calculate the average piece weight of the sample. | • Add additional samples or continue with less accurate weighing |
Virus Specimen Collection Tube
Inspection principle:
It can perform protein denaturation on fresh clinical virus samples to inactivate the virus, prevent secondary transmission of infection, and ensure the safety of transportation and testing personnel.
♣.Structural composition: Combination of cotton swab and transport medium (VTM).
♣. Product requirements:
The product should be airtight, avoid high temperature, avoid direct sunlight storage. It should be used in a clean, hygienic, pollution-free, and temperature-friendly environment.
♣, Storage conditions and validity period:
â‘ , the product should be stored in a clean, dry and ventilated environment,
②, the temperature is 5℃-35℃;
â‘¢, relative humidity <85%RH;
â‘£, product shelf life: 12 months.
♣. How to use
â‘ Before sampling, mark relevant information on the label of the sampling tube.
â‘¡. Sampling with the corresponding cotton swabs.
â‘¢ After the collection is completed, quickly put the cotton swab into the collection tube, break the part higher than the sampling tube, and tighten the tube cover.
â‘£. For the specific sampling method, please refer to the following:
a) Nasal swab Gently insert the sampling head into the nasal cavity, stop for a while and then slowly rotate to exit, immerse the collected specimen in the Xiangxiang solution, break the excess part and discard it, and tighten the sampling tube cover.
b) Pharyngeal swab: Wipe bilateral pharyngeal tonsils and posterior pharyngeal wall with the sampling head, immerse the collected specimen in the sampling solution, break off the excess part and discard it, and tighten the cap of the sampling tube.
c), Mycoplasma Chlamydia, Ureaplasma specimen collection
Male: Insert the sampling head into the urethra about 2cm and rotate, stay for a while and then exit, and immerse the collected specimen in the sampling solution.
Female: Wipe the mucus of the cervical orifice, insert the sampling tip into the cervical canal for 1-2 cm for sampling, immerse the collected specimen in the sampling solution, break off the excess part and discard it, and tighten the cap of the sampling tube.
♣. Precautions
1. After the virus is collected, the disposable sampling swab should be completely inserted into the preservation solution, so that the virus can be retained to the greatest extent possible.
â‘¡ The collected specimens must be sent for inspection in time.
â‘¢. It is forbidden to use products with damaged packaging and expired validity period to prevent pollution.
This single-use Virus Sampling Tube is used for in vitro diagnosis. It cannot be used for human or animal oral or external use. If swallowed, it may cause serious events; it is irritating to eyes and skin. If it is not splashed into the eyes, rinse with water.
