Open the package case and please check the following parts to see
if any missing or damaged. If so, please contact your dealer immediately.
2.1 Check the scale before. Please do not use it if any part missing or
damaged.
2.2 Please do not weight items that are over the maximum capacity of
the scale. This could damage the scale.
2.3 Please try to place the item in the middle of the scale pan and do
not shake, never let any items (include the helix line) contact with
the scale, otherwise will influence the precision.
2.4 Please do not storage or use the scale at a place where is high
temperature, high humidity, explosive, flammable or strong
electromagnetic fields.
2.5 Please do not change the internal circuit of electronic scale.
2.6 Please do not pull the helix line, this could damage the scale.
2.7 Please replace the battery when battery alarm on.
2.8 Before use, please confirm whether the power is for single-phase
AC power use, otherwise it will damage the scale.
2.9 Cover the cap on inlet/outlet port after each use.
2.10 Turn the scale off after each use. If the unit is to be stored or not used
for long time, take the battery out of the electronic scale. The scale

the weight will display accurately as the resolution in the technical
parameter form.
5.5 CHARGE MODE
This function allows the user
to quickly and conveniently
charge a system in a minimal
amount of time. Simply turns

The scale is not only a stand-alone scale but also can be compared
1. Make sure all connections are correct and tight (refer to following
illustration):
2. Turn the scale on.
3. Place refrigerant tank on scale. Wait for the reading to settle out.
e.g. The refrigerant tank is 12 Kg, the following screen will appear:

6. If the scale is not connected to the AC power, the solenoid valve will
not work. The scale’s buzzer will alarm when charging nearly finish
(refrigerant ≤0.05 Kg). when the charge is completed, stop the charge
system manually. Press the “Enter” key exit to screen, the scale will
display the gross weight of refrigerant tank.
2. Turn the scale on.
3. Place refrigerant tank on scale. Wait for the reading to settle out.
e.g. The refrigerant tank is 12 Kg, the following screen will appear:
4. Press “Charge” key, the Charging Indicator will appear, and enter the

previous operation, then press “RECOVER” key ,the previous screen will appear.
b. If you want to finish earlier during recover mode, press “CLEAR” key to stop.
c. If the entered recover weight is more than the gross weight of tank, the scale
will display “ERROR”, please re-enter the recover weight.
d. It is very dangerous if the recovering weight is more than 80% capacity of the
refrigerant tank.
The “Repeat” key is used to repeat the previously entered charge
/recover weight. After the first charge/recover cycle is complete, press
the “Repeat” key, it will start to charge/recover the same quantity as
last time.
5.7 REPEAT MODE
Caution: If there is a mistake or system is down, please press
