Resolution

The resolution (minimum incremental weight or volume) that can be displayed by the REF- METER-OCTA can be adjusted to make the display easier to read. Unstable loads or high winds can cause the display to fluctuate erratically. By reducing the display resolution, external influences can be minimized. As shipped, the REF-METER-OCTA is set to MEDIUM resolution, suitable for most purposes. The resolution can be changed to LOW,

MEDIUM or HIGH by repeated pressing on the keypad. Table 1 illustrates the displayed resolution for each units mode vs. resolution. Regardless of the resolution setting, the scale operates internally with the highest resolution; therefore, only the displayed value is affected.

activated. can be used during the RUN mode similarly as described in the HOLD MODE section. The REF-METER-OCTA-PLUS provides additional functionality when using the RUN mode. Refer to the REF-METER-OCTA-PLUS User’s Guide for details.

Tank Capacity Mode

It is often convenient to know the relative amount of material (i.e. refrigerant) remaining in a container (tank). The REF-METER-OCTA’s Tank Capacity Mode allows a continuous display of the percentage of material remaining in a tank. In order to compute the percentage accurately, the REF-METER-OCTA must be trained to know the weights of an empty and full tank. To train the REF-METER-OCTA Tank Capacity Mode, perform the following steps:

REF-METER-OCTA User’s Guide

English

Tank Capacity Mode Training

1.While holding down, press . The SET TANK indicator will turn on, and OFF will show on the display. This indicates that the Tank Capacity Mode is currently off.

2.Turn the Tank Capacity Mode on by pressing . The display will show ON, and the Alternate Numeric Display and Percent Indicator will turn on.

3.Press to proceed to the first step of training. 0% will flash in the Alternate Numeric Display indicating that the weight of an empty container must be registered.

4.Apply an empty container (or a load representing the weight of an empty container) on the platform. Wait 5 seconds for the load to stabilize, then press . 100% will flash in the Alternate Numeric Display indicating that the weight of a full container must be registered.

5.Apply a full container (or a load representing the weight of a full container) on the platform. Wait 5 seconds for the load to stabilize, then press . This completes the training process, and the SET TANK indicator will turn off.

6.From this point forward, the Alternate Numeric Display will show the percent of material remaining in the container from 0% to 100%.

NOTE: The 100% weight must be larger than the 0% weight by at least 200g. If not, “Err” will show on the Alternate Numeric Display. To clear the error, retrain as above using a 100% weight that is at least 200g larger than the 0% weight. During training, the ZERO key may be used to assist in setting the 0% and 100% values. This will have no effect on the training, as the Tank Capacity Mode relies on absolute, not relative, weights.

Calibration

The REF-METER-OCTA is calibrated at the factory to provide high accuracy. While recalibration should seldom, if ever, be necessary, recalibration is performed easily without sending the product to the manufacturer for service. A known calibration weight (in kilograms) is required to recalibrate the scale, and can be any value between 5 kg and 100 kg. 25 kg is recommend. Best accuracy is obtained by using the largest weight available (i.e. a 50 kg calibration weight will provide better calibration accuracy than a 5 kg calibration weight). In addition, it is necessary to know the weight to within 2 grams.

To recalibrate the REF-METER-OCTA, perform the following steps:

1.Place the REF-METER-OCTA weighing platform on a firm, level surface.

2.Turn the power to the REF-METER-OCTA off.

3.Remove all objects from the platform.

4.While holding , press and release . The REF-METER-OCTA will turn on, and after a few seconds the display will show SET CAL and 25.000 kg.

5.Using or adjust the displayed value (in 1g increments) so that it is equal to the weight of the reference calibration weight. Use the key to adjust in 1 kg increments.

6.Press . A number representing the weight of the unloaded platform will appear on the display. Press to lock in this value. The display will read zero.

7.Apply the calibration weight to the platform. A number representing the applied reference weight will appear on the display. Allow at least 10 seconds for this number to stabilize.

8.Press . The REF-METER-OCTA is now recalibrated to the reference weight.

9.Refer to the Quick Start section above for setting the desired Units and Resolution.
