Operation & Product Features
Power Up Test: When the scale is turned on, all display
segments will appear for approximately 3 seconds before
resetting to zero or disappearing and 0 being displayed.
Stable Reading Indication: On the display, a down arrow will
appear in the lower left corner indicating that the weight
reading is stable. During weighing, this down indicator
disappears and will reappear once a stable reading has been
reached.
Weight Unit Indication: On the display, one of the four right
facing arrows on the right side will appear indicating the
weight unit selected: kg, lb, oz or lb:oz. (kg, lb or oz only for
ES200L)

Overload: If the applied load exceeds the capacity of the
scale, an E will appear on the display and the load should
be removed immediately. The scale will return to normal
operation.
Negative Value: When a load is removed from the scale, any
zeroed value will be displayed as a negative number. To
return to normal operation, the zeroed value can be cancelled
by pressing On/Off/Zero.
Zero Function: Values can progressively be added to a
sample. By pressing the On/Off/Zero key, the scale display
returns to zero. After adding additional mass, press On/Off/
Zero to zero the scale again. Additional mass may be added
up to the capacity of the scale. While removing the sample
from the scale, a total gross weight of the sample will be
displayed as a negative value. Zero the scale again before
subsequent usage.
Low Battery Indication: The display will show Lo when the
batteries are weak and need to be replaced.
Auto Shut-O : To extend battery life, the scale will automati-
cally turn off after approximately five minutes if no key press or
active weighing is occurring. This feature is only active with
battery operation.
Two Button Keypad
On/O /Zero: Pressing this key turns on the scale. The same
key operates the zero feature when the scale is ON. A long
press of three seconds will turn the scale off.
Units/Cal: Press this key briefly to change the weighing unit.
The following weight units may be selected: kilogram (kg),
pound (lb), ounce (oz), or pound:ounce (lb:oz), (kg, lb, or
oz only for ES200L). Pressing and holding this key longer will
start the calibration process.

Calibration
For best results, calibrate the scale at regular intervals. This is espe-
cially important if the scale is in use for prolonged periods.
1. Allow the scale to warm up and stabilize for two
minutes before commencing the calibration
procedure.
2. Press and hold the Units/Cal key until CAL
flashes on the display.
3. Press the On/Off/Zero key to capture the scale
zero. The platform should be empty and the
display shows -C-
4. After the zero is captured, the display will show
xxx. The value xxx is the span calibration
weight.
. Place the calibration weight on the platform and
press On/Off/Zero key. The display will again
show -C-.
6. After span capture, the display will return to the
normal weighing mode.
NOTE: If CAL E appears on the display, a calibration
error has occurred and the process should be re-
peated. The message CAL E will appear if the
calibration steps are not followed in the correct order
or if an incorrect calibration weight was applied.
