Offer using instruction and guidance.
1 Year warranty period. After the goods are received, customer can contact us for after-sale service if there is any problem.
If products were confirmed after received, but have tolerance problem during the usage, we can also offer free calibration, customer need to pay for the delivery cost.
Due to the nature of weights, only class F2 /M1 or below can be 2nd calibrated.
Our handsome client who purchased anti-slip countertop truck scale and send us his pictures with our goods. Thanks for his trust and kind feedback.
*Calibration weights for moisture meter
*Calibration weights for electronic scales
Generally, electronic scales should be calibrated with 1/2 or 1/3 of the full scale range. The standard calibration process is as below:
Turn on the scales, warming up for 15 minutes, and calibrate 0 bit. Then use weights to calibrate in sequence, such as 1kg/2kg/3kg/4kg/5kg, keep the readout to be the same weight of weights, the calibration process is done.
Different scales will need different class of weights:
Balance with 1/100000 tolerance and minimum scale 0.01mg is excellence level balance. It need to be calibrated with E1 or E2 weights.
Balance with 1/10000 tolerance and minimum scale 0.1mg will use E2 weights to calibrate.
Balance with 1/1000 tolerance and minimum scale 1mg will use E2 or F1 weights to calibrate.
Balance with 1/100 tolerance and minimum scale 0.01g will use F1 weights to calibrate.
Scale with 1/100 tolerance and minimum scale 0.1g will use M1 weights to calibrate.
The scales and balances can be calibrated by corresponding value and class weights.
*Elevator loading test
It’s a common method for elevator loading test. The balance factor test of the elevator also needs to use the weights. The balance factor of the elevator is one of most important parameters of the traction elevator, and important parameter for safe, reliable, comfortable and energy-efficient of the elevator. As an important function, the test of balance factor is included in the acceptance inspection project. 20kg cast iron weights “rectangular weights” (M1 OIML standard weights) with 1g tolerance is used for elevator inspection. Generally, elevator companies will equip with small cast iron weights ranging from 1 ton to several tons.
The special equipment inspection institute also needs to use the cast iron weights for the elevator loading inspection. The common sizes are: 20KG cast iron weights (convenient for handy, easy to lift), and secondly some inspection units will choose 25kg cast iron type.
*Calibration of heavy duty weighbridge/truck scales
Calibration on corners: Choose weight in 1/3X value( X instead of weighbridge’s total capacity), put it on the four corners of the platform and weigh separately. The readout of four corners can’t out of allowable tolerance.
Linearity calibration: Choose weights in 20% X and 60% X, put them on the center of weighbridge separately. After comparing the readout with weights’s value, the deviation should not exceed allowable tolerance.
Linear calibration: Select 20% X and 60% X weights, place the standard weight in the center of the weigh scale countertop, weigh separately, and the reading should be compared with the standard weight. The deviation should not exceed the allowable error.
Display value calibration: Average full weighing capacity into 10 equal parts, set standard value according it, put standard weight in the center of weighbridge, then record the readout.
*Calibration of livestock scales
Livestock scales are used to weighing livestock. To keep the accuracy of scales, cast iron weights can be used to calibrate the livestock scales.
*Pallet truck scales
It is integrated in hand pallet truck and scales together. With a pallet truck scales, transporting and weighing can be done at the same time. Make your in-house logistics more efficient with lower cost.
Crane scales are used for weighing a hanging load , with different range and weighing capacity, offer a solution for the problem how to weigh a nonstandard oversized load under industrial conditions Generally used in industry of steel, metallurgy, factories, mines, freight stations, logistics, trade, workshops, etc., such as loading, unloading, transportation, metering, settlement, etc. Industrial heavy-duty digital crane scales available from 100kg to 50tonne capacities
