SYSTEM DESCRIPTION AND INTENDED USE

SYSTEM DESCRIPTION:

The SRV930 medium capacity counter top scale employs the latest in microprocessor and load

cell technology to provide accurate and repeatable weight data. Operated by one (1) 9-volt battery,

the scale can be used in a fixed location or as a portable scale.

The low power microprocessor circuitry allows the SRV930 scale to derive its power from one (1)

9-volt battery or for continuous operation, the optional AC adaptor (SRV930AC).

The animal’s weight is displayed on a 4½ digit LCD display.

INTENDED USE:

The SRV930 scale is designed for use as an animal weighing system for animals not exceeding 44

pounds. Please read the following warnings to avoid injury to the animal or attendant.

STORAGE and TRANSPORTATION

STORAGE:

If storing this equipment for periods longer than three (3) months, remove the battery. To maintain

proper operation of this instrument, storage and transport conditions should not vary outside the

following conditions: Ambient Temperature 41F to 95F (5C to 35C).

TRANSPORTATION:

To transport the SRV930 scale from one location to another within the office, use the handles to

lift and carry. If moving from inside to a mobile location, SRI recommends using the soft-sided

carry case (SRV930CC) to protect the scale from outside elements.

BASIC SYSTEM OPERATION

TURNING SYSTEM ON:

Make sure the scale is free and clear of any obstructions and then press the “TARE/ON/OFF”

button to turn the scale on. When scale is ready, “0.00” will be displayed.

Kg/Lb FUNCTION:

Press the “Kg/Lb” button to toggle between lb, oz, lb-oz, or kg displayed weighing units.

The scale will remain in the last mode used unless manually changed. For example: If the last

weight recorded was in kilogram and the scale is shut down, the weight mode will be in kilogram

when the scale is turned back on.

TARE:

The tare function is used to subtract any additional weighed items (example: receptacle) from the

patient’s net weight.

MEMORY:

Press the “MEMORY” button to store the “last weight” for recall if needed. To view the last

stored weight from memory, press the “MEMORY” button again to return to the original value.

“MEMORY” will hold last stored weight until the memory is replaced with another stored

memory (the memory will not zero).

NOTE: The “MEMORY” button will not store weight that is less than two pounds (one

kilogram).

HOLD ARROW INDICATOR:

The HOLD ►arrow at the left bottom of the LCD display will at first flash while weighing. Once

weight has stabilized the arrow stays solid.

REWEIGHING (NEXT USE):

To reweigh the same or different patient, be sure the tray is free and clear of any objects. Press the

“TARE/ON/OFF” button to zero the scale. When “0.00” is displayed the scale is ready for use.

TURNING SYSTEM OFF:

The SRV930 scale can be programmed to auto-shut down at 120, 180, 240, or 300 seconds.

Pressing the “TARE/ON/OFF” button until the scale turns off will conserve on the battery life.

To change the auto shut down time press the “TARE/ON/OFF” button to turn the scale “ON”.

Press and hold the “Kg/Lb” button until the display reads “UNIT”. Press the “Kg/Lb” button

until the display indicates “A.OFF”.

Press the “MEMORY” button once. The display will indicate one of the following “OFF, 120S,

180S, 240S, or 300S”. Toggle the “Kg/Lb” to select the desired shut down time. Once selected,

press the “MEMORY” button to save. The display will revert back to “A.OFF”. Press the

IMPORTANT

CALIBRATION CHECK Qualified service personnel only should perform this

procedure. Load cells have no user serviceable components and should not be tampered

with for any reason. Re-calibration is generally not required, but should be verified

periodically to ensure accuracy. The recommendation for calibration check is at least

once every 12 months, or as individual maintenance policy requires.

IMPORTANT

This scale is factory calibrated and ready for use.
