PRECAUTIONS FOR USE
1. Please keep the indicator in a cool place. Do not store it at a high temperature.
2. Please keep it clean and avoid hosting of cockroach and any other possible live creatures.
3. Avoid objects impacting with the indicator. Do not drop loads onto the scale or subject the
platter to any physically strong shock.
4. The load placed on the platter must not exceed the maximum weighing capacity of the
scale.
5. The indicator is IP68 waterproof design. Only the cables with Φ3 to 5.5mm caliber can be
used, or the indicator’s waterproofness will be affected.
6. Clean and wrap the scale into a clean bag for long time no use. A desiccant sachet may be
included to prevent any moisture built up.
7. To avoid current leakage, please do not subject the batteries to excessive heat or attempt
to open the batteries.
8. In order to maintain the re-chargeable battery in good condition it should be kept fully
charged whenever possible. If the scale is to be stored, the battery should be fully charged
before storage, and then re-charged at 3 month intervals.
9. The number of times that the battery can be recharged will vary according to the conditions
of use. However it can be maximized by re-charging the battery frequently and by avoiding
conditions of total discharge. The battery cannot be overcharged.
10. Please operate or charge the scale in an open area. Do not squeeze the power cord to
avoid wire on fire.
11. If the scale is not working properly, please send it to our distributor for service.
12. Any suggestion for the product is warmly welcome.
BEFORE USING THE SCALE
Thank you for purchasing an EXCELL Electronic
Digital Indicator. In order to use the indicator
properly, please read this User Manual carefully
before use. If you have a problem concerning the
indicator, please contact your supplier.

EXCELL PRECISION CO., LTD.
PREPARING TO USE THE SCALE
1. Locate the scale on a firm level surface free from vibrations for accurate weight readings.
2. Avoid operating the scale in direct sunlight or drafts of any kind.
3. If possible, avoid connecting the scale to AC power outlet sockets which are adjacent to
other appliances to minimise the possibility of interference affecting the performance of the
scale.
4. Remove any weight that might be on the platter before the scale is switched on and avoid
leaving weight on the platter for long periods of time.
5. All goods weighed should be placed in the centre of the platter for accurate weighing. The
overall dimensions of the goods being weighed should not exceed the dimension of the
platter.
6. Once the scale has been powered on, it will go through a LCD display test and it is ready
for use when the display shows zero.
7. The scale requires 15 to 20 minutes warm up before operation to ensure best accuracy.
8. When the power bar indication turns to be low battery , it means the battery
should be recharged immediately.
9. Introduction of Storage Battery
02006100 ZSME300000379

EXCELL PRECISION CO., LTD.
No burning
Caution Corrosion
Due to the storage battery adopt the advanced free-maintaining technique, customers need not
to replenish electrolyte.
The scale should be recharged every 3 months to prevent failure of the internal rechargeable
battery.
1. The battery should be charged for 8~10 hours.
2. The temperature of battery should below 45°C.
Maintaining
1. Please do not discharge with over-current when using the battery. Please charge the battery
after discharging current.
2. Please take down the battery when the scale is not used for a long time or break the
connection of cathode.
3. Do not short the battery terminals to check whether there is current. Please check whether
the connection point is firm to guarantee good connection.
4. The battery should be replaced by specialized person. No reverse-battery or the product
will be damaged.
a) Anode of battery should be connected with Anode of product battery (usually red cable)
b) Cathode of battery should be connected with Cathode of product battery (usually brown
cable or black cable)
c) See the following picture:
Safety warnings
1. The electrolyte of battery is caustic which causes metal, cotton, etc to corrode.
2. The hydrogen will be resolved when using or charging the battery and it will cause explosion
when approaches fire.

CHAPTER 2 BASIC OPERATING FUNCTIONS
PH3 has three weight modes: Simple, Limit and Target, press to
switch.
Simple weight mode
In this mode, the weight value can be displayed by means of analog and
digital. For example, when an object weighs 20 kg, the LCD2 shows the digits
20 and LCD1 has slight changes on its graduation.
Limit weight mode
This is a weight check mode, press “HI” and “LO” keys to input high and low
limit values, LCD1 displays if the weight on platter is greater than the high
limit, lower than the check value or equal to the OK range. When it meets the
OK range, the OK zone will blink. For example, High limit = 20, Low limit = 18,
then OK range is between 18 and 20.
Target weight mode
Use this mode to set a “Target” weight and an allowable range. When the
weight is within the range, it means the weight meets the target requirement.
For example, pour liquid into a container, press “OK” key to set target as 30
and press “Range” key to set an allowable range as ±2, when the weight
reaches the range between 28 and 32，the OK zone on LCD1 will blink.

RS1 07 & RS1 08 Settings Instruction
1. Under auto transmission mode, if RS1 07 and RS1 08 are all set at “00”, no matter what
weight it is, no any data of the weight will be transmitted out.
2. Under auto transmission mode, if RS1 07 is set between “00 ~ 99”, and RS1 08 is set at
“00”, when the weight is over or under the zero range that set in RS1 07, after being
stable, the data of weight will be transmitted out; if the weight is back to the zero range
(RS1 07,) and then becomes higher or lower than the range again, after being stable, the
data of weight will be transmitted out (the format is set in RS1 03.)
e.g.: When RS1 07 is set at “05”, RS1 08 is set at “00”, and RS1 04 is set at “02”, if the weight
is less than 5g, no data of weight will be transmitted out.
Put on a weight of 6g, after being stable ST, NT, +00000006g
If take off the weight of 6g, weight column displays “0g”
No transmission (because it’s in the zero range)
Put on a weight of 50g, after being stable ST, NT, +0000050g
If take off the weight “48g,” weight column displays “2g”
No transmission (because it’s in the zero range)
Add the weight to 30g, after being stable ST, NT, +0000030g
And so on…
3. Under auto transmission mode, if RS1 07 is set at “00” and RS1 08 is set between “00 ~
99”, as long as the weight is higher than “0”, after being stable, the data of weight will be
transmitted out. And then, the weight becomes the benchmark, as long as the weight
changes higher or lower than the range of RS1 08, after being stable, the data of weight
will be transmitted out. To sum up, on condition that the weight changes and after being
stable, the data of weight will be transmitted out (the format is set in RS1 03.)
4. Under auto transmission mode, if RS1 07 is set between “00 ~ 99” and RS1 08 is set
between “00 ~ 99”, as long as the weight is higher or lower than the zero range set in
RS1 07, after being stable, the data of weight will be transmitted out. To sum up, on
condition that the weight changes, not including “0”, after being stable, the data of weight
will be transmitted out (the format is set in RS1 03.
