PREPARING THE SCALE FOR USE
STANDARD BENCH SCALE
Xpress Standard Bench Scales are designed to meet the real world requirements of manufacturing, agricultural, packaging, and general weighing applications, and are ready to use right out of the box.
The Xpress Standard Indicator is a rugged, reliable electronic weighing indicator in an IP65 washdown enclosure designed for easy operation in washdown applications. The Xpress Standard Bench stainless steel platforms (XMC-S, XWS-S and XWT-S) are also manufactured to be used in washdown applications.
Xpress Standard Bench mild steel platforms (XMC, XWS and XWT) are intended for use in general purpose industrial and commercial environments. For the best performance, they should not be used in environments requiring washdown, immersion in liquids, or exposure to corrosive chemicals
This chapter gives detailed instructions and important information regarding the successful installation of the Xpress Standard Bench Scale.
ENVIRONMENT
Before you install the scale, identify the best location for the equipment. The proper environment enhances its operation and longevity. Keep in mind the following factors, which might have a negative influence on the scale's operation:
Vibration: Vibration diminishes the scale’s ability to measure accurately. Electrical machinery such as conveyors and drill presses can cause inaccurate and non-repeatable readings. The scale may also read inaccurately if it is not leveled properly.
Air currents: Moving air can cause the scale to read wind movement as an additional force and cause inconsistency in the weighing results.
Friction: A scale cannot measure accurately if an object is rubbing or pressing against the scale platform.
UNPACKING AND ASSEMBLY
Thank you for purchasing an MT Xpress product. Please inspect the package immediately upon receipt. If the box is damaged, check for internal damage and file a freight claim with the carrier if necessary. If the container is undamaged, open the box, remove the scale and place it on a solid, flat surface. Please keep the packing material and shipping insert in case you need to return the scale to an Xpress representative.

POWER UP/DOWN SEQUENCE
Power Up: Press the power key to turn on the Xpress XIS. It goes through a series of self-tests when it is turned on. The scale performs diagnostics on its internal memory, and precedes to normal the operating mode. The power up sequence is as follows:
z All segments of the display segments and cursors light to verify operation.
z Next the unit displays the software part number; revision number, geo value and country one by one.
z The unit captures zero and is ready for normal operation.
Note: Before switching on the scale, always make sure there is nothing on the platter. If you have powered up the unit with something on the scale, the scale may not find the zero value, and shows “------“. To clear this condition remove the item, press the power key until the unit displays “off”, then press the power key again, the scale will then capture the correct zero value.
Power Down: Press the power key until “OFF” is shown on the display to turn off the scale.

OPERATING YOUR SCALE
STRAIGHT WEIGHING
Place the item to be weighed on the platter.
Remove the item from the platter and the display will return to 0.000.
RE-ZERO FUNCTION
There are two ways to re-zero the scale:
Power-up Zero: The scale will automatically capture zero when it is turned on. The power-up zero capture range is +/-10% of the scale capacity.
Note: When the scale is turned on with a weight on the platter is more than 10% of the capacity, the scale will not capture zero (the weight display will show "-----") to indicate that the scale will not be ready for use. After removing the weight the scale will capture "zero".
Push-button Zero:
The ZERO key sets the gross zero value over a range of +/-2% of the scale capacity. To use this function, the scale must be in the gross weighing mode (NET cursor dark) and in a no-motion condition. When the weight on the platter is more then +/-2% of the scale capacity depressing the zero key will not yield a result until the weight is removed and the Zero key has been depressed a second time.
TARE FUNCTION
The
key subtracts the weight of the container or wrapping material placed on the scale prior to
weighing a desired item.
Place the empty container or wrapping material on the platter, e.g. 5 lb.
Press the
key, it show net weight 0 lb, the net weight cursor should light.
Place the item to be weighed onto the platter or into the container or wrapping material.
Note the net weight value and record it if necessary.
Remove the weighed and container or wrapping material from the platter, the display will show the
negative net weight of the container, e.g. -5 lb. This indicates the net weight of the container.
Press
key to return the scale back to gross weighing mode, proper execution of this function is
indicated when the net cursor is not illuminated.

GRAVITY ADJUSTMENT
The Standard Indicator has built in compensation provisions to allow factory calibration with destination correction capabilities to compensate for variances on gravitational forces. If the Standard Indicator is subjected to a different gravitational force at its destination location, this can be compensated for electronically by adjusting the geo value. The geo value has 32 settings. The geo value for any world location can be found in the Geo Value Table in the Appendix as long as the geographical coordinates and elevation above sea level are known.

After replacing a load cell, the overload stops must be checked and adjusted (if needed). Refer to the next section for the overload stop adjustment procedure.
Thread the load cell cable through the column from the bottom.
Connect load cell cable to terminal.
Coil the excess load cell cable and insert it into the column. A small length of tape applied to the ends
of the coils allows the cable to slide into the column easier.
Apply power to the scale.
Recalibrate and test the operation of the new load cell.

OVERLOAD STOP ADJUSTMENT
The overload stops must be checked and reset if the top or bottom frame or the load cell has been replaced.
Remove the stainless steel platform from the base.
Using the proper size feeler gauge, check all six overload stops as shown in the figure below. The
correct gap measurements can be found in the table below.
If the gaps are not set properly, proceed to the following steps.
Loosen the overload screw jam nuts. Refer to the figures below.
Using the proper size feeler gauge, turn the screw until you feel a slight drag on the feeler gauge.
Tighten the jam nut and recheck the gap. Readjust if necessary.
Adjust all six overload stops using this procedure.
Reinstall the platform and make sure the scale weighs to full capacity.

SHIFT TEST
23
A shift test verifies that the scale weighs correctly irrespective of load placement. If the scale does not pass the shift test, verify the overload stops gaps before replacing the load cell. No adjustment for the shift is possible. If the scale does not pass the shift test, the load cell must be replaced.
For NTEP and Canadian Weights and Measures tests, use weights equal to 1/2 the scale’s capacity. Place the test weight sequentially at each of the positions A, B, C, D and E as shown in figure in the right. These positions are the centers of the four quadrants of the platform and the center of the platform. Note the terminal’s reading of the weight at each position. The difference between any two positions in the shift test cannot exceed the tolerance shown in the table below.
