(%) Percent Weighing:
User Action Balance Response
1 Place an empty container on the weighing pan
and press the ZERO button.
Zeros are displayed.
2 Place the sample which represents 100% in the
weighing container. Display indicates the weight of the sample in the unit of measure you have
selected.
3 Press the FUNCTION button (or MODE and
RANGE buttons simultaneously for dual
range models).
Display cycles repeatedly through PCS, HI-OK-LO, CAL1, CAL2, T , and %.
4 Press the MODE button when CAL 100
appears on the display.
Display will indicate % and 100.00. This means that the weight on the pan now
represents 100.00%. You are now in the percent weighing mode with all
weight readings displayed as a percentage of the weight of the sample used in
Step 2.
5 If you want to exit the percent weighing mode,
press the MODE button.
You are now in the weighing mode you used just before selecting percent
weighing.
( T ) Live Animal Weighing / Severe Environment Weighing:
User Action Balance Response
1 Press the FUNCTION button (or MODE and
RANGE buttons simultaneously for dual
range models).
Display cycles repeatedly through PCS, HI-OK-LO, CAL1, CAL2, T , and %.
2
Press the MODE button when T appears on
the display.
T appears in the display and you are now in the time averaging weighing
mode.
3 Place a container/cage on the pan. T appears in the display as well as a slowly increasing weight of the
container/cage.
4 When the display has stabilized, press the
ZERO switch to zero out the container/cage
weight.
T appears in the display as well as zeros.
5 Remove the container/cage and place the
sample/animal in the container/cage.
A slowly decreasing negative weight is displayed.
6 Replace the container/cage with the enclosed
sample/animal on the weighing pan
After the sample/caged animal is placed on the pan, the weight reading will slowly stop
decreasing and then slowly start increasing as the weight reading is averaged over time.
When the weight stops drifting upward, you have reached the final time averaged weight
reading.
7 If you want to reach the final time averaged
weight reading more quickly, press the
FUNCTION switch (or the RANGE switch on
dual range models). This resets the time
averaging mode.
The final time averaged weight reading is reached more quickly.
8 If you want to exit the time averaging
weighing mode, press the MODE switch.
You are now in the weighing mode you used just before selecting the time
averaging mode.
Floating Tare™ (dual range models only):
Floating tare is only active when the balance is in LO range. Floating tare yields low range resolution throughout the entire high range
capacity of the balance. A typical example using floating tare would be where you combine different components by weight to
produce compounds. The procedure is as follows.
1.
Select LO range by pressing the RANGE button until LO briefly appears in the display.
2. Place container on weighing pan. If the container weight exceeds LO range capacity, OL is displayed. If the container
weight does not exceed the LO range capacity, the container weight is displayed.
3. Press the ZERO button. The display returns to zeros and LO range.
4. Add the first component until the target weight is reached. Then press ZERO.
5. Add the second component until the target weight is reached. Then press ZERO.
6. Continue until all components have been added.
Floating tare allows you to enter the LO range from anywhere within the full capacity range of the balance. This feature is particularly
useful when adding small amounts to large tare loads and compounding where weights are accumulated. Floating tare is only active
when the balance is in LO range. Pressing the ZERO button returns the display to zeros in LO range. While you are using the floating
tare feature, it is easy to lose track on how much capacity has been used. For this reason the Capacity Tracking feature is a helpful
tool. Please see the discussion under that heading.
