1. Introduction

The hanging scales of the PCE-HS N series are applied in industrial sectors as well as in private
sectors. The scales stand out due to a long life time, a simple design and useful functions. They are
delivered as a ready-to-work article, so that you can start as soon as the package has arrived.

Functions of the hanging scales:

- Auto ON / OFF function (can be deactivated)

- Various measurement units: kg, lb and N (Newton)

- Mode for weighing animals (filter for moving objects)

- Several Hold functions (Auto HOLD / Key HOLD / AUTO key HOLD)

- Peak value indication (PEAK)

- Backlight

2.Technical specifications

2

The scales may only be plugged into a socket with earth conductors (PE) according to
regulations. The protective effect cannot be abolished by using an extension line without
earth conductors. In case of voltage supplies from networks without connected earth
conductor, a comparable protection according to the effective installation guidelines is to be
built by a specialist.

- In case of operation in surroundings of more strict safety requirements the relevant guidelines must be followed.
Use only extension lines with earth conductors.

- If the line cord is damaged, the device has to be disconnected from the power network, effective immediately,
and the line cord has to be replaced.

- If there is any reason to doubt a risk-free operation of the scales, the device has to be disconnected from the
power network and safeguarded against accidental operation.

- The instruction manual is to be read by every operator and must be always within reach at the workplace.

- Do not enter the danger zone, regardless of whether the scales are loaded or unloaded.-

DANGER

Do not place any flammable material onto, under or next to the device. Do not operate the scales in possibly
explosive areas. Please be cautious not to let any fluids get inside the device or into the connections at the back
of the device. In case a fluid is spilled onto the device, disconnect the device immediately from the power
network. The device may only be reinstated, after inspection by a competent PCE Inst. specialist.

Instruction Manual

3. Delivery content and assembly

Please check immediately, after the package has arrived, whether the following items are included.

Delivery content: 1x hanging scales PCE-HS N series, 1x hook, 1x shackle, batteries and

instruction manual.

Assembly:

1. Please remove the packaging from the scales.

2. Insert battery into scales.

3. Attach mounting parts to the scales.

4. Precautions

4.1 “LO” = Low battery voltage

In case a battery load is lower than 3.4 V ±0.1 V, the scales will show an error indication
“LO” at the display. Then the batteries should be replaced. You will require three 1.5 V AA
batteries.

4.2 “ooooo” = overload

If the scales are loaded above its maximum range, the display will indicate “ooooo” (see table).
Please unload the scales and check them afterwards. That error indication may also occur if
the calibration of the scales is wrong and the scales assume to be overloaded. Please perform
a calibration of the scales then.

5. Disposal

For the disposal of batteries, the 2006/66/EC directive of the European Parliament applies. Due to the
contained pollutants, batteries must not be disposed of as household waste. They must be given to
collection points designed for that purpose.

In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use them
or give them to a recycling company which disposes of the devices in line with law.

If you have any questions, please contact PCE Instruments.?

6. Operation

6.1. Starting the scales

In order to start the scales, please press the button at the control panel. The scales will first shortly
activate all segments of the display (1st image) and will then show which HOLD functions are activated
(2nd image shows HOLD key). Then the scales will automatically skip to the scaling mode (3rd image) and
the weighing can be started.

Since the scales only indicate weights above 10 d (compare with table “minimum load”) it may

occur that later on these values will lead to faulty measurements. We advise to press the
button previous to every weighing to delete the values that cannot be indicated.

6.2. Tare function

The scales have a tare function, e. g. in order to subtract the packaging from the gross weight.

- To do so, hang the empty container onto the scales, so it will only indicate the weight of that package.

- Then press the button, so that the display will show again.

- You can also use the tare - function repeatedly (multiple tare).

The range for the tare function of the scales covers the entire
weighing range. However, please consider that the weighing range of
the scales cannot be extended with that function. For example, if you
have the 50 kg scales and you use the tare function with a container
of 5 kg, you will only have a total weighing range of 45 kg left. So if
the maximum weighing range is exceeded, the display will indicate
the following error notice:

6.3. Measuring unit “UNIT”

The scales can perform measurements in ”kg” (kilograms), in “lb” (pounds) and “N” (Newton). The
measuring unit is indicated at the right corner of the display. The “unit” switch is installed at the back of
the scales. The unit that is set will remain active as long as you do not switch to the next unit.

1 kg = 1000 g
1 kg = 2.204 lb
1 kg = 9.81 N

6.4. AUTO Power OFF

The scales have an automatic switch-off function to preserve the batteries. If the scales remain un­operated for 5 minutes (no alternation of the weight, no manipulation of the keys), the scales will switch
off themselves. But this function can also be deactivated. Press and hold the ”UNIT” key at the back of

the scales while also pressing the button in order to start
the scales. “P-ON” (power on) will be indicated in the display for a
short time. If you activate the scales this way, they will remain
active until you switch off the scales yourself by pressing the

button or until the batteries are flat. At the next start of the
scales the AUTO Power OFF function will be active again. Thus
an unintentional waste of the battery power of the scales will be avoided.

6.5. Backlight

The display lights of the scales will be activated as soon as the scales are in use. If the scales are not
operating, the lights will shut down after 5 seconds. This adjustment is preset and cannot be changed.

6.6. Adjustment / calibration

The scales have the option of a linear adjustment. Hereby the scales are adjusted
with several weights. Thus a more precise accuracy for the entire weighing range is
achieved.

To do this, press the key and the “UNIT“ key at the back of the scales, hold

both keys pressed while starting the scales via the key. “CAL” will be
indicated in the display. Now release the keys and the display will indicate “S-20”.
Via the “Unit“-key, you can now search for the weighing range of the scales, e. g. S-

150, which can then be confirmed by pressing the key. After that there will be
a number in the display, e. g. 28353. Now you have to put the scales into the wanted

calibration position and then press the key.
As soon as the weight required for the calibration will be indicated shortly in the
display, the adequate calibration weight must be hung onto the scales. Then you

have to wait until the value is stabilized. Then press and the next weight to
hang on for calibration will be indicated in the display (e. g. PCE-HS 150 N shows: 40
kg / 80 kg / 120 kg and 150 kg). You have to hang each of these weights one after
another onto the scales for proper calibration. Follow each step until the display
indicates “End”.

If “FAIL“ is written on the display, the adjustment went wrong and you are advised to
repeat all adjustment steps.

6.7. HOLD function (MAX and weighing animals)

The scales support various “HOLD“ functions. The HOLD functions determine when to show a result in
the display of the scales.

In order to access the adjustment options for the “HOLD“ function, press and hold the key, so that
several HOLD functions will be shown one after another.

HOLD / ANIMAL Mode to weigh animals

This function allows weighing moving objects Therefore the scales
automatically calculate an average value out of several weights. The
average value will be indicated in the display after 6 … 8 seconds. The
average value is calculated from approx. 14 … 16 measurements.

PEAK Indication of maximum value

This function keeps the maximum value in the display until that value is
exceeded. This function is often used for tensile tests (500 ms … 0.5 s).

HOLD / AUTO Automatic Hold of value

This function automatically freezes the value in the display, as soon as it
is stable. The stability will be indicated at the left upper corner of the

display as a circle. Further weighings can be performed by pressing the
“HOLD” button. During the measuring process, the “HOLD” symbol
flashes. As soon as a stable value is reached, the “HOLD” symbol will
freeze in the middle upper area of the display and will not flash anymore.

For further questions and information on calibration, please contact us: PCE Inst.

HOLD / KEY Freezing value by key press

This function freezes the value in the display that is indicated during
pressing the “HOLD” button. Therefore the value does not need to be
stable. For further weighing please press the “HOLD“ button again.

HOLD / AUTO / KEY HOLD by key press for stable values

The value will only be frozen in the display after the “HOLD” key is
pressed and the value on the display is stable enough.
