OPERATOR’S MANUAL
Introduction
The SRS2 is a rugged wireless scale designed
specifically for weighing refrigerant cylinders. The
wireless remote control is securely stored inside the
back of the rugged scale platform. The remote has a
bright blue backlight. The remote can be hung by the
magnetic hat for easy, hands-free measuring. The
platform is made of solid aluminum with rubber cor-
ners to protect against the hazards of daily use.
SRS2 Quickstart
Operation:
1. Turn on the remote. The platform will turn on
automatically if synchronized and in stand-by
mode.
2. Zero (tare) the scale by holding the ZERO button
on the remote for one second.
3. Press the UNITS button on the remote to select
pounds or kilograms.
4. Read weight directly on the remote’s display.
SYNCHRONIZATION:
If “no Sig” or “CH USEd” is displayed when the
remote is powered on, you need to SYNC the
remote to your platform.
1. Check that the platform is powered on.
2. Hold the SYNC button on the remote until search
pattern appears.
3. During the search, hold the SYNC button on the
platform until green SYNC LED blinks.
4. If the sync is successful, the SYNC LED will go
solid and a reading will be shown on the display.

Major unit reading, in pounds (Lb) or kilograms (Kg).
Minor unit reading, in ounces (oz) or grams (g).
Combine with major unit for total weight.
For example: if the upper display shows 14 Lb and
the lower display shows 11.50 oz, the total weight is
14 Lbs and 11.50 oz.
Tech Tips for the Field
Respect the environment
Always use low loss hose fittings to minimize
harmful refrigerant gases entering the atmosphere.
Hoses affect weight
There are two ways to handle this issue:
EASY WAY
Connect the hoses to the system before zeroing
the scale. Once the system is stable, log the
weight displayed before disconnecting from the
system.
HARD WAY
Zero the scale without hoses connected. Then,
connect hoses to the system, and add or recover
refrigerant. Disconnect the hoses from the system
and the tank. Now the display will show the
weight of the added or recovered refrigerant.
Maintenance
Clean the exterior with clean dry cloth. Do not use
liquid.
Battery replacement:
Separate battery indicators
for the remote and the platform are shown on the dis-
play.
Replace the remote’s battery with a NEDA type
1604 9V battery. The scale platform will also indicate
low battery by the illumination of the LOW-BATT
LED. When this is lit, replace the platform batteries
with 6 AA batteries.
