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. Refer to Balance Kit Contents and AZI Part Numbers on page 17 for a complete list of
the contents of the kit and the associated AZI part numbers.
Operating Environment
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 and
not in direct sunlight. The surface should not be magnetic and should be located away from doors,
windows, heaters, air conditioners and fans.
Figure 1 - Balance Full View

AZI Customer Service 800-528-7411 Manual, ZSP-150-F Page 5 of 22
Leveling the Balance
Adjust (turn) the front feet (see Figure 2) to level the balance by centering the bubble in the level
indicator, which is shown in Figure 1. Turning the foot as shown below raises that side of the
balance and an opposite adjustment lowers it. Turn both feet together to raise or lower the front of
the balance. When properly adjusted the metal center shaft of the assembly will protrude from the
center of the plastic foot and will support the balance. The plastic foot will be raised up against the
bottom of the balance and will not be touching the weighing table.
Connecting to an Electrical Outlet
The balance is supplied with a 115/230 VAC, 50/60 Hz automatic switching, remote power supply
with five international plug adapters. This power supply will work with most electrical outlets.
However, before making any connections, verify that the power (VAC) requirement shown on the
power supply is compatible with the AC power outlet to which the balance will be connected and the
proper plug adapter for your outlet is installed on the power supply.
First, plug the round connector into the rear panel receptacle.
Then, plug the power supply into an AC outlet.
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 10.
AZI recommends that the balance be plugged into an electrical outlet at all times. This ensures that
the balance is always warmed up and ready to use.

AZI Customer Service 800-528-7411 Manual, ZSP-150-F Page 11 of 22
CAL 2 - Linearity
Linearity is set in the balance’s software at the factory during the manufacturing process. It requires a
special set of weights that are not available commercially. When a CAL 1 function is performed the
linearity is automatically reset as well. Unless the balance is damaged the linearity will not change.
Therefore, CAL 2 should never be performed by the user.
Capacity Tracker
The capacity tracker located between the 0% and 100% at the bottom of the front panel display
provides a graphic display of the used and unused portions of the weighing range. Each segment
represents 10% of the balance’s total capacity. As 10% of the balance’s capacity is used the first
segment will illuminate. As 20% of the balance’s capacity is reached the second segment will light
and so on.
Selectable Vibration Filters and Stability Indicator
Balances are equipped with three user-selectable vibration filters, which reduce fluctuating readings
in varying weighing conditions. The balance was delivered to you set in the high filtering mode (Fil
HI). This is the most aggressive filtering mode. Normal filtering (Fil nor) and low filtering (Fil Lo) can
be selected for quieter conditions and faster response.
The stability indicator, OK, is illuminated when the variance of the readings are below the preset
stability parameters as selected by the user. The stability indicator is useful in determining the
stability of the weighing environment. In normal weighing the OK stability indicator should come on
within five seconds after the sample has been placed on the pan and the windscreen is closed. If the
stability indicator does not come on or takes a very long time this indicates it is too noisy of an
environment for that level. Try improving the environment or raise the filter level To enter the
selection mode proceed as follows: To exit the selection mode and return to normal operation, turn
the balance off and then back on again at any time.
To enter the filter selection mode, proceed as follows:
