IV.
General Use Instructions:
Please refer to these instructions for daily use of this scale. These instructions simulate the
procedure for every day usage.
ON AND OFF LOADING USAGE:
To start with a new, FULL tank that will be loaded on & off, please follow these steps:
Please choose a method of usage by Tare or Net Weight:
TARE
: You must know the weight of your empty tank, and any other equipment mounted on
to the tank that will affect the weight. Add this weight together, and turn the black tare knob on
the front of the indicator until it reads that number in the negative. Turn the knob counter-
clockwise in order to achieve negative numbers. Once that negative tare weight is set, you
may load the tank, and apply other equipment on that tank. The weight that registers on the
scale indicator is the NET WEIGHT, or weight of the contents. At this point you will not change
the black tare knob unless you are loading on a new tank. As you use the contents, the weight
decreases. When the tank is at zero, or close to it, you will begin again by removing the empty
tank, setting the tare weight with the black knob (for the new tank + equipment), and begin
using the material again.
NET:
If you do not know the tare weight (it is not stamped on the tank), you may know the Net
Weight (contents in the tank). If this is the case, you will use this procedure:
Load on your full tank and attach any equipment that affects the weight on the scale. Turn the
black tare knob on the front of the indicator until it reads the known NET WEIGHT (weight of
contents only) on the indicator. Clockwise will increase the readings and counter-clockwise
will decrease the readings. When the weight is set for the contents in the tank, do not adjust
this again until you load on a new tank. The reading will decrease until you have used all the
contents in the cylinder, where it will read 0 lb./kg. Start a new tank by removing the old empty
tank, loading on a new full tank, and attaching equipment, and set tare knob to Net weight
again.
For use when FILLING the TANK instead of on & off loading:
To start with a new, EMPTY tank that will be filled while on the scale base, please follow
these steps:
Load the new, empty tank on to the platform. Be sure to connect all equipment to the tank that
may apply weight to the scale. With this weight applied, turn the black tare knob located on
the outside, front of the indicator, until the digital reading says zero. This means that your
digital reading will show net weight, or the weight of the contents alone. As you fill the tank for
the first time, the scale shows the current weight at all times. Do not readjust the tare weight
unless you are starting with a dry, new, empty tank. Any residual weight will reflect what is left
in the tank, and should not be changed unless a new tank is put on the base.
V. Calibration
Procedure:
The Model 4042™ and 4042WB™ Secondary Spill Containment Scale is
pre-calibrated at
the factory to within specified accuracy
and is calibrated to standards traceable to the
Bureau of Weights and Measures.
No further calibration should be necessary. If the
electronics or load cells in the base are being replaced, the following procedure should
be used.
1. Plug the AC Cord into a well-grounded receptacle. There is no power on / off switch, so
power is applied as soon as it is plugged in.
2. Allow approximately 15 minutes warm-up time before calibration.
