NOTE: False readings may occur if the scale is used in environments having high
electrical noise. False readings may also occur if the cylinder touches the case or
controls, or if anything touches the platform, especially the cord to the control box.
TIF9020A Electronic Scale
SETUP
1. Place the unit on a firm and level surface.
2. Remove the control box from the case in order
to provide clearance.
3. Switch unit on by pushing the ON/OFF button.
4. Select the desired unit of measure by pressing
and releasing the UNITS button. Three scales
are available:
lbs./oz. (0 lbs. 0.0 oz.)
decimal pounds (0.000 lbs.)
kilograms (0.000 kg)
OPERATION
1. Carefully place refrigerant cylinder in center of
the platform.
2. Connect refrigerant cylinder to a charging mani-
fold via utility hose if charging refrigerant, or to
a recovery machine if recovering refrigerant.
3.
Open refrigerant tank valve. Purge air from hoses.
4. Press ZERO button; display changes to zero.
5. Open manifold valve(s), or turn on recovery
unit. Refrigerant begins to flow, and display
indicates the weight being removed (if charg-
ing) or added (if recovering). A minus sign (-)
appears if weight is being removed.
6. Monitor the display; when desired charge or
maximum allowable fill is reached, close the
cylinder valve and manifold valves, and/or
switch off the recovery unit.
7. When operation is complete, turn unit off by
pushing the ON/OFF button. Close cylinder
valve, disconnect hose(s), and store the unit.
LOW RESOLUTION MODE
In normal operating mode, the high resolution of the
scale may lead to noticeable fluctuations in the read-
ing caused by weight shifts or wind. To improve this
situation, a low resolution mode may be activated.
1. With scale switched on, with any unit or weight
displayed, press and hold the UNITS button.
2. The enunciators (units of measure) will begin to
flash.
3. Release the button and continue normal opera-
tion. Resolution is now reduced by a factor of 5
(1.0 oz./.050 lbs./20 g) and will provide stable
readings under extreme conditions.
4. To return to the normal resolution mode,
depress and hold the UNITS button until the
enunciators stop flashing.
WEIGHT MEASUREMENTS
The unit may be used strictly as a weight scale.
1. Follow steps 1 through 4 in Setup.
2. Press the ZERO button. Display changes to zero.
3. Carefully place the object (e.g., cylinder) that is to
be weighed directly in the center of the platform.
4. Gross weight will be displayed.
5. When weighing has been completed, turn unit off.
This feature is especially useful when recovering. To
calculate the amount of refrigerant in a tank, subtract
the "Tare" weight (marked on cylinder) from the dis-
played amount to find the quantity of refrigerant in
the cylinder.
OVER-RANGE INDICATION
If the gross weight applied to the platform exceeds
the specified range, the unit will display a single 1 at
the left of the display.
BATTERY INSTALLATION
The BATTERY enunciator will appear when the battery
needs replacing. A display of “---” indicates battery
voltage insufficient for operation. Replace battery in
order to resume operation.
1. Remove battery from control box by removing the
battery cover located on the back of the box.
2. Disconnect the battery from the battery clip.
3. Attach a new 9V alkaline battery to the clip.
4. Install new battery and cover.
