SYSTEM DESCRIPTION AND INTENDED USE
SYSTEM DESCRIPTION
The SRV945-BT Portable Platform Scale is a low profile design, which allows the animal easy
step access. The SRV945-BT Scale can be used in a fixed location or as a portable scale. The
Scale employs the latest in microprocessor and load cell technology to provide accurate and
repeatable weight data. Four (4) identically matched transducers are strategically placed to ensure
an accurate representation of the animal’s weight.
The animal’s weight is displayed on an LCD screen. With a push of a button, weight data may be
viewed in either pounds or kilograms.
The SRV945-BT Platform scale is equipped with a Bluetooth wireless module. By waking the
scale up with the “WEIGH” button the wireless feature is turned on. Then use the free SR Scales
app (Google Play store) to connect with the scale to allow for remote wireless operation.

BUTTON FUNCTIONS
ZERO/WEIGH
The “ZERO/WEIGH” button is used to zero the system before placing a
patient onto the scale system. Ensure that nothing is in contact with the
weighing surface during this procedure. The display will read “0.0 LB”(or
KG). The button also wakes up the display and shows the patient’s weight if it
should Auto Power Down before the weighing process is done.
HOLD/RECALL
The “HOLD/RECALL” button freezes the displayed weight and stores it away
in memory. Press “HOLD/RECALL” to store the weight into memory.
To recall last weight reading, press “HOLD/RECALL”button once scale has
shut down.
LB/KG
Weight data may be viewed in either pounds or kilograms. Pressing the
“LB/KG” button allows the operator to toggle between the two readings.
Pounds are displayed in a resolution of 0.2, kilograms are displayed in a
resolution of 0.1.

BASIC SYSTEM OPERATION
SETTING SYSTEM ZERO
Make sure the scale is free and clear of any obstructions. Press and hold the
“ZERO/WEIGH” button to zero the system. In a few seconds, the display will
read “0.0 LB”(or KG). It is recommended that the system be zeroed prior to each
new patient.
After the scale has been set to zero, position the patient on the scale. Display will indicate the
patient’s weight in either pounds or kilograms.
In this default mode, the weighing surface remains active. If scale shuts down, press the
“ZERO/WEIGH” button once to wake display and take reading.
HOLD/RECALL
The scale display is designed to automatically lock the reading on the display,
and store the reading in memory, once the weight is stable. If scale cannot lock
in reading due to patient movement, press the “HOLD/RECALL” button to
automatically lock the display and store the reading.
To return to WEIGH mode when finished, press the “ZERO/WEIGH” button once. The display
will become active.
Once the scale has shut down, the last stored weight can be recalled by pressing the
“HOLD/RECALL” button. Last stored weight will be displayed until the scale shuts down or the
“ZERO/WEIGH” button is pressed.
BATTERY REPLACEMENT
The Portable Platform Scale contains six (6) AA alkaline 1.5-volt batteries. The low battery
indicator is displayed when the battery power is insufficient to power the scale.
Refer to Assembly Instructions (Figure 2).
