Unpacking and Setup
The balance, weighing pans, remote power supply and windscreen are packed in a
foam support to protect them from shock during shipping and handling. Save and reuse
all packing material for future shipments. A null modem cable, a 100g weight and this
user’s manual are also packed with the balance.

AZI SP-150 balances are equipped with a special clamping screw that locks the balance
suspension during shipping. This screw must be loosened before the balance can be
operated (see Figure 1).
Locate the black knob, on the front center of the balance, underneath the display
area.
•Remove the paper tag.
•Turn the knob, approximately one (1) turn counter clockwise, as shown in
Figure 1, until it stops.
If the balance is shipped or moved long distances, the clamping screw should be re-
tightened by turning the knob in the clockwise direction until resistance is felt,
approximately one (1) turn.
Figure 1 - Unlocking Clamping Screw
The environment in which your balance is used is very important. Air movement,
temperature changes, vibrations, direct sunlight, etc. influence the performance of high
precision balances. Therefore, place your balance on a solid, sturdy surface that is free
of air currents and vibration. The surface should not be magnetic and should be located
away from doors, windows, heaters, air conditioners and fans.
Level the balance by turning the front feet to center the bubble in the level Indicator.
Turn a foot clockwise to raise that side or counter-clockwise to lower that side of the
balance.
Turn both feet together to raise or lower the front of the balance.

Before making any connections, verify that the power requirement shown on the remote
power supply is compatible with the AC power outlet to which the balance will be
connected. First plug the round DIN connector into the rear panel receptacle.
Then, plug the power supply into a grounded AC outlet. Do not alter or bypass
the ground plug in any way. Doing so adversely affects the performance of the
balance.
NOTE: Your balance must be plugged in and switched on for at least one (1) hour,
then calibrated, prior to use. Please see the calibration instructions on page 9.
The On/Off Switch
Press the ON/OFF switch and observe the turn on sequence shown below.
Figure 2 - Turn On Display Sequence
During this sequence the balance is doing an automatic systems check to verify it is
functioning properly.
**NOTE: The clamping screw must be unlocked before turning the balance on or the
balance will not be able to complete the automatic systems check.

Connecting the SP-150 to the Vapor Pro
The balance is configured to interface directly with the Vapor Pro series of Moisture
Analyzers. Weight readings at the balance can be transmitted directly to the Vapor Pro
through the null modem cable connection.
To enable this communication between the balance and the Vapor Pro:
Power to both units should be switched OFF.
Connect the null modem cable (AZI P/N 200-0069) to the RS-232 connector at
the rear of the balance. Connect the other end of the cable to the balance
connector at the rear of the Vapor Pro.
Switch the power to both units ON.
On the Vapor Pro, press the [Menu] key. Use the [Down] key to highlight the
SETUP MENU. Press the [Selct] key to access this menu. Highlight the EXT
BALANCE SETUP option and press [Selct]. Highlight and select the SELECT
BALANCE DRIVER option. Use the [Edit] key to select AZISP150 as the
external balance. Press [Quit] and then [Accpt] key to program this option.
Select the CHECK BALANCE COMM option to verify the cable is connected and
that the Vapor Pro and the balance are communicating. Use the [Esc] key to
return to the MAIN MENU.
If the Communication Check is not successful, the balance’s communication settings
need to be reset to their factory presets. Refer to RS-232 Front Panel Configuration
on page 12 for instructions on resetting the balance to the required factory presets.
From the MAIN MENU, select the MEMORY START MENU and then ADD/EDIT
MEMORY START. Access the memory start to be edited using the [Up] or
[Down] keys and the [Selct] key. At the SAMPLE WEIGHT ENTRY MODE
option, select DIGITAL BALANCE.
When a test is run using that memory start parameter, the Vapor Pro will automatically
check for data communication. The weight readings from the external balance will be
displayed on the Vapor Pro display. Follow the display prompts to proceed through the
weighing and testing sequence.

The Zero Switch
Pressing the ZERO switch at any time returns the display to zeros. When a weighing
that has been zeroed out is removed from the pan, a negative reading is displayed. To
return to zeros, press the ZERO switch.
The Mode Switch
Pressing the MODE switch starts the unit of weight cycle as follows: grams (g), carats
(ct), pennyweights (dwt), troy ounces (ozt), and ounces (oz). Press the MODE switch a
second time when the desired unit of measure appears. For Vapor Pro operation, verify
that the balance is weighing in grams (g).
The Send Switch
The SEND button is not normally employed in everyday usage of the balance, although
it is used in certain specific configuration procedures, as detailed later in this manual.
The Function Switch
Pressing the FUNCTION switch cycles the display through four functions as follows:
PCS - front panel parts counting
HI OK LO - check weighing
CAL 1 - auto-calibration
CAL 2 - factory set - DO NOT USE
CAL 2 is set at the factory and should never require further adjustment. The procedure
for CAL1 begins on page 9. For the other two functions (PCS and HI OK LO), refer to
the appendices beginning on page 19.

CAL 1 [Auto-Calibration] - Using an external calibration weight
Perform auto-calibration every time you move your balance. It is extremely important to
use high quality weights and verify the balance has been warmed up for at least one (1)
hour prior to calibration.
Procedure
Display Reading
Remove any containers or weights so
that only the stainless steel pan is in
place. Press the ZERO switch.
Zeros are displayed.
Press the FUNCTION switch.
Display cycles repeatedly through PCS, HI-
OK-LO, CAL1, and CAL2.
Press the MODE switch when CAL 1
appears.
CAL 1 and a flashing 0 are displayed.
Wait 10 seconds then press the ZERO
switch.
The display stops flashing. In approximately
10 seconds a weight value or two alternating
weight values flash on the display.
Place the displayed weight or one of
the alternating weights on the pan.
The display stops flashing and the selected
weight are displayed.
Wait 10 seconds then press the ZERO
switch.
The weight continues to be displayed while
the calibration takes place (approximately 10
seconds). The display blanks, then displays
"OK" and the calibration weight.
Remove the calibration weight.
The display returns to zeros and the normal
weighing mode.

Capacity Tracker
The capacity tracker provides a graphic display of the used and unused portions of the
weighing range. Each segment represents 5% of the balance’s capacity and is
illuminated as that portion of the capacity is used. The larger segments, representing
¼, ½, ¾ and full load, flash as they are approached and then become solid again as
they are exceeded.
Selectable Vibration Filters and Stability Indicator
All balances are equipped with three vibration filters and a stability indicator to adapt to
varying weighing conditions. The balance is delivered set in the high (Fil HI) mode,
which is the most aggressive mode. Less filtering (Fil nor or Fil Lo) can be selected for
quieter conditions and faster response.
The stability indicator “OK” is illuminated when the balance has determined that all
readings are within the filter parameters the user has selected. If the weight readings
are outside the acceptable limit, the stability indicator will not light. The stability
indicator can be disabled if desired.
To enter the vibration filter selection mode, proceed as follows:
