Frequently Asked Questions - M601620 ADE

How do I change the battery in my ADE M601620 scale?

Open the battery compartment on the underside of the scale. Remove the old batteries and insert two new AAA batteries observing the correct polarity. Close the compartment securely.

What units of measurement does the scale support?

The scale supports kilograms (kg), pounds (lb), and stones (st). Press the unit button on the back to cycle through units.

Why does the display show 'Err' or 'OL'?

'Err' usually indicates an unstable weight measurement. Stand still and try again on a hard, flat surface. 'OL' (Overload) means the weight exceeds the maximum capacity of 180 kg. Remove the weight immediately.

How do I clean the scale?

Wipe the scale with a soft, damp cloth. Do not use abrasive cleaners or immerse the scale in water. Dry immediately after cleaning.

Where is the best place to use the scale for accurate readings?

Place the scale on a hard, flat surface such as tile or hardwood flooring. Avoid carpets or uneven surfaces as they can affect accuracy.

How do I reset the scale if it is not turning on?

First, check if the batteries are installed correctly or if they need replacement. If the scale still does not power on, remove the batteries for 30 seconds and reinsert them. This acts as a reset.

Can I use the scale on a carpet?

No, the scale is designed for use on hard, flat surfaces. Using it on carpet may result in inaccurate weight readings.

What is the tare function and how do I use it?

The tare function allows you to zero out the weight of a container. Place the empty container on the scale, press the tare button (if available), and then add the item to be weighed. The display shows only the net weight.

How do I change the unit from kg to lb?

Look for a unit button on the back or bottom of the scale. Press it to cycle through kg, lb, and st. The selected unit will appear on the display.

What should I do if the scale displays inconsistent readings?

Ensure the scale is on a stable, level surface. Stand still and evenly distribute your weight. If problems persist, replace the batteries and recalibrate by pressing the platform firmly once (refer to manual). If it continues, contact ADE support.

Assembly

Dismantle packaging and foil carefully. Weighing platforms are equipped with castors and a handle for easy transport.

(1) Move the scale to the place of use.
(2) Connect both platforms to each other with the connecting cable.
(3) Connect the indicator with the corresponding cable to the jack connector at one of the weighing platforms.
(4) Connect the attached mains adapter to the indicator.
(5) Afterwards connect the mains adapter to the socket. The rechargeable batteries need 24 hours power supply to achieve full battery load.
(6) Start the scale by pressing the ON key.
(7) The scale is ready to use
(8) Follow the steps under the chapter "Operations".

Power supply

Power is supplied either by the rechargeable battery in the display unit or by the mains power via the supplied power unit. The imprinted voltage value at the mains adapter must match the mains voltage at the place of use. Connect the mains cable to the indicator and to a socket.

The wall socket must be located near to the unit and be easily accessible. Please use only the mains adapter supplied by ADE. The mains adapter is charging the battery pack during normal operation.

When the battery is being charged for the first time a sufficient charging period of approx. 24 hours is necessary to achieve a full battery load.

If the unit is in battery mode and the display indicates – Lo, the battery needed to be recharged with the mains adapter. For a full battery load a charging period of 12-16 hours is required with the scale being switched off. If–Lo still appears at the display inform your service partner.

Replacing the rechargeable battery

The battery compartment is located on the front of the unit.

1) Open the battery compartment.
2) Remove the battery cables carefully from the housing, connect the wires (red to red, black to black) and insert the battery into the housing.
3) Close the battery compartment again.

Only use original rechargeable batteries and charger units from ADE. The warranty does not cover any damage caused by using other types of batteries or charger units.

Tips for handling the batteries

The life of a battery depends essentially on the load, frequency of use, temperatures, settings and the accessories used.

– New batteries or batteries that have been stored for long periods require a longer charging period.
– Charge the batteries at room temperature.
- Never expose the batteries to temperatures below -10^ (14°F) or above 45^ (113°F).
- Rechargeable batteries lose their charging capacity over the time and require a longer charging period the older they are. If the battery performance drops considerably, then it is time to replace the battery.
- New batteries are supplied in partial charged condition. Batteries achieve their full capacity after several complete charge and discharge cycles.
- Do not throw old rechargeable batteries into the domestic waste. Ensure that the valid legal and municipal regulations of your country are being followed.
- Never dispose of batteries in fire as they can leak or explode!

Operation

Modes of operation

- Weighing mode

The "weighing mode" is of course the standard mode of your scale. After initial configuration and sealing (by attaching a calibration sticker to the back of the unit), the ADE-scale can only be operated in this mode.

- Setting mode

Date, time and consecutive numbers for print commands are being set in this mode. To start setting mode, hold the GROSS/NET key pressed until TIME appears on the display.

- Configuration mode (set-up mode)

The values for different parameters including the calibration could be set in the configuration mode. This function is for authorized service personnel only.

- Test mode

There are different diagnostic functions for the ADE-MAK in test mode. This is for service personnel only.

Manipulations to test and configuration modes can revoke the calibration status and will result in loss of warranty!

Before weighing

1. Move the wheels of the bed onto the weighing platforms.
2. The constructions do not allow to pass over the weighing platform. In any case ensure that the wheels of the bed are secured and the brakes are engaged.
3. Switch on the scale.
4. An automatic function test will lead to zero indication (0.0). The weight of the bed is being ignored automatically.
5. Place the patient into the bed. The displayed weight is the weight of the patient.
6. If the weight of the patient should be ignored as well (e.g. for dialysis purposes), follow the instruction under the point "Tare function".
7. If the weight of the bed including bed-clothes is already being stored follow the instruction under the point "Restore the preset tara value"
8. The indicator is now giving the weight of the bed.
9. To evaluate the weight of the patient please follow the instructions on page 7 chapter Use of the scale section to take patient's weight.
10. Place each of the platforms in front of the wheels of the bed.

Weighing

Press the ON key for at least 3 seconds to turn the scales on. An automatic function test will be conducted afterwards. The test is done when the display shows zero. The scale is now ready for the weighing procedure.

Resetting the scales back to zero: Wait until the standstill status indicator ▲▲ (14) appears. By entering the ZERO key (8), measuring inaccuracies after switching on the scale are being compensated. The zero key re-starts the scale. The status indicator (6) →0←appears when the scale is being resetted.

Tare function

The TARE key (9) is useful for many weighing operations. Tare might be useful in case the patient is being placed on the scale/bed with items (e.g. clothing, bed clothing shoes or other items) which should be ignored by the scale. Weigh these items first. After the weight is displayed, press the TARE key (9) to reset the display back to zero. The display changes to net mode (NET status indicator (5) is on) and shows zero.

Note: Taring the bed with subsequent determination of the patient weight is not possible/practical, as the bed weight is subtracted from the maximum load of the scale and thus only a small weighing range is available. To determine the patient weight, proceed according to section "Before Weighing" on page 7.

Entering manually tare - values:

The user is able to insert manually the gross weight, which is for example mentioned at the identification plate of the bed. Enter the appropriate tare value just by using the key pad under normal weighing mode. The value will be stored after use of the ENTER key (or TARE). The ADE-display is now ready for weighing and changes to net mode [NET status indicator (5) is on]. Enter the tare button to leave this mode.

Preset tara

Press and hold the PRESET TARE key (10) for approx. 3 seconds. PRO PT X appears on the display. Select the memory location 1-10. Now enter the TARE VALUE which you would like to be ignored by the scale and confirm same with ENTER. The value is displayed as a negative figure and will be deducted when a load is being placed on the scale. Enter the on/off, zero – button (8) to leave this mode.

Restore the preset PRESET TARA value:

Press the PRESET TARE key (10). "Pt x" appears on the display. Enter a number from 0-9 (memory location for the tare value). If no new number will be inserted to change the already displayed value within five seconds, the unit will turn back to weighing mode and displays the last stored value as negative figure as above.

Enter the on/off, zero - button (8) to leave this mode.

Displaying the gross weight, net weight and tare value:

Press the "0" key to change between the net weight (gross weight minus the tared value) and the gross weight.

8 M601620-210422-Rev008-UM-e

Hold function

The determined weight could be continued being displayed even when the load has already been removed. That enables taking care of the patient first before reading the results.

To use the hold function the scale must be at standstill. The standstill status indicator ▶▲(14) is on and Hold appears at the digital display. Deactivate the HOLD function by pressing the key again.

Determining the Body Mass Index (BMI)

The BMI figure is an index showing the ratio between height and weight.

$$ \text { BMI } = \frac {\text { body weight }}{(\text { height }) ^ {2}} \quad \begin{array}{l} \text { To determine this value you need the height of the person. } \ \text { Start the scale and weigh the person following the steps under weighing. Then } \ \text { press the BMI key(11)to start BMI mode. The last value entered appears on the } \end{array} $$

display. Use the numerical key pad to enter a new value for the height (in cm) or retain the value, which is already been displayed. Confirm the value entered with the ENTER key or delete same by using the CLEAR key. After the entry has been confirmed by the ENTER key, the BMI value will be calculated using the weight on the scales. The display changes between weight value and BMI value "b xx.x" (every two seconds) for a period of 3 minutes. Press the BMI key (11) to cancel before this time has expired.

Evaluating Body Mass Index

BMI evaluation according to WHO

BMI < 16 Severely underweight

16 - 17 Moderately underweight

17 - 18.5 Slightly underweight

BMI 18.5 - 25 Normal weight

BMI 25 - 30 Overweight

30 - 35 Obese Class I

35 - 40 Obese Class II

40 Obese Class III

Print out a record

The scales must be at standstill, e.g. standstill status display ▲▲ (14) appears at the screen.

Press the ENTER key (13) to send the data to the serial interface.

Note: Printing is not possible if the net weight is 0. The print function only produces one print-out. A reset is required to print out another copy.
