REF-METER-OCTA User’s Guide English

Unpacking the REF-METER-OCTA

1. Remove the REF-METER-OCTA from the carry bag.

2. Push the signed part of the control box to remove it from the storage dock. The storage dock is placed on the low side of the weighing platform.

3. Pull out the control box from the storage dock. When using the REF-METER-OCTA, ensure the cable does not touch the top of the weighing platform to avoid inaccuracies.

4. If desired, extend the mounting hook.

Repacking the REF-METER-OCTA

1. If extended, restore the easel of the control box to the retracted position.

2. Hold the control box and press the yellow auto reel button on the side of the platform.

3. Push the control box firmly into the storage dock of the weighing platform until it snaps in place.

4. Replace the REF-METER-OCTA into the carry bag.

Battery Installation & Replacement

1. Remove the battery cover from the rear of the control box by compressing tab at the base of the battery cover.

2. If necessary, remove old set of batteries.

3. Insert 4 ‘AAA’. Replace battery cover by aligning tabs and snapping back into place.

IMPORTANT: TO PREVENT DAMAGE TO THE REF-METER-OCTA, CAREFULLY OBSERVE BATTERY POLARITY AS MARKED INSIDE THE BATTERY COMPARTMENT. DO NOT LEAVE DEAD BATTERIES INSIDE THE CONTROL BOX. REMOVE BATTERIES IF THE REF-METER-OCTA IS NOT TO BE USED FOR AN EXTENDED PERIOD OF TIME.

Resolution

The resolution (minimum incremental weight or volume) that can be displayed by the REFMETER-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 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.

Over Range Indication

If the weight applied to the weighing platform exceeds the maximum capacity of the REFMETER-OCTA (100 kg), a single “1” will be shown on the left side of the display. To prevent damage to the REF-METER-OCTA, immediately remove the weight from the platform.

Hold Mode

A special feature of the REF-METER-OCTA allows the emptying or replacing bins or containers used for weighing without affecting the weight shown on the display. This Hold Mode may be used as follows:

1. Allow load to settle until display is steady.

2. Press

. The current weight is now locked on the display.

3. Remove, empty, or replace objects, bins, or containers on the platform.

4. Wait 5 seconds for the new load to stabilize.

5. Press

Programming

With the REF-METER-OCTA, a programmable threshold weight will sound an alarm. The alarm will sound when the displayed weight (either positive for increasing weight, or negative for decreasing weight) equals the programmed weight. To program the alarm, perform the following steps:

1. Set up the REF-METER-OCTA with the desired units and resolution as described in the

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:

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.

Battery Level Indicator

The battery level indicator shows the relative strength of the batteries. Full power is indicated by four bars. As the batteries are depleted, the number of bars displayed decreases, until no bars are left. At this point, it is necessary to replace the batteries (refer to the Battery Installation section above). If the battery power drops to the point where the REF-METER-OCTA can no longer function accurately, the power will turn off automatically. When the batteries are replaced, and the scale is turned back on, the REF-METER-OCTA will resume operation with all previous setting intact.

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 after a few seconds the display will show SET CAL and 25.000 kg.

5. Using or weight of the reference calibration weight. Use the

6. Press the display. Press

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

, press and release . The REF-METER-OCTA will turn on, and

adjust the displayed value (in 1g increments) so that it is equal to the

key to adjust in 1 kg increments.

. A number representing the weight of the unloaded platform will appear on

to lock in this value. The display will read zero.

. 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.

English REF-METER-OCTA User’s Guide

Restoring Factory Calibration

If you make a mistake recalibrating the REF-METER-OCTA, you can always restore the factory calibration (and factory defaults) of the scale.

To restore the factory settings perform the following steps:

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

2. Remove any objects from the platform.

3. While holding beep 10 times. The factory settings are now restored.

Sound

As delivered from the factory, the REF-METER-OCTA beeps when turning on and when keys are pressed. This sound can be muted as follows:

1. Make sure the power is on.

2. While holding

section. This will allow you to know at any time the percent of refrigerant remaining in the refrigerant cylinder.

3. Carefully set the refrigerant cylinder on the weighing platform.

4. Attach the cylinder to the charging manifold via a utility hose. Open the cylinder valve and purge air from the hose (ie. REFCO CL hoses).

5. Program the desired refrigerant charge weight as described in the Programming section. Activate the program by pressing

6. Open the manifold valve(s).

7. The display will indicate the weight charged as negative, indicating refrigerant is being removed from the charging cylinder.

8. If the refrigerant cylinder empties while charging:

a. Close all valves. b. Press

to “freeze” the display .

c. Replace the empty refrigerant cylinder with a full one. Attach and purge hoses. d. Press

to exit the Hold Mode.

e. Open manifold valve(s). Charging will continue from where it left off.
