lb/kg keys until the desired sample rate is displayed then press the HOLD/REL key to save the
setting. Note: Like the filtering level, the sample rate may be changed later without having to enter
the calibration mode.
AUTOMATIC SHUTOFF
The display will now indicate ASH= which is the prompt for the selection of the Automatic Shutoff
feature. This feature will automatically turn the CN20 off after a predetermined period of inactivity. To
turn the instrument back on you must press the ON key. This feature helps prolong battery life by
turning the CN20 off when it is not in use. After pressing the HOLD/REL key, use the ZERO key to
select the desired number of minutes (1 through 9) of inactivity before turning the CN20 off. Entry of
the number zero (0) disables the Automatic Shutoff feature. Press the HOLD/REL key to save the
setting. Note: This setting may be revised without having to enter the calibration mode.
SLEEP MODE
The display will now indicate SLP= which is the prompt for selection of the Sleep feature which can
also be used to conserve battery power when the indicator remains unused for a selected period of
time. If this feature is enabled, the load cell excitation will be reduced and the display will be reduced
to one scrolling segment after remaining at zero for the selected time from 1-9 minutes. Unlike the
Automatic Shutoff feature which only requires that there be no motion on the indicator to activate, the
Sleep feature requires that the indicator remain at zero (0) to activate. To enable the Sleep feature
after pressing the HOLD/REL key, use the ZERO key to display a number of 1 to 9 which
corresponds to number of minutes of inactivity while at zero (0) before the indicator will automatically
enter the Sleep mode. Press HOLD/REL to store the setting. Entry of zero (0) turns this feature off.
PUSH BUTTON TARE
With the display showing Pbt= press the HOLD/REL key to show current setting, then press ZERO
to select YES (enable) or NO (disable). Must be NO if equipped with standard (Figure no. 7) keypad.
Press the HOLD/REL key to save setting.
AUTOMATIC HOLD MODE
The display will next indicate HLd= which is the prompt for the selection of the Automatic Hold mode.
This mode of operation is used to lock the CN20 display and is used only in noncommercial
applications. After pressing the HOLD/REL key, enter a YES to enable or a NO to disable by pressing
the ZERO key, then press the HOLD/REL key. This feature must be set to NO for “Legal for Trade”
applications.
NON-ROLL-UP MODE
The CN20 display will now indicate nrU= which is the prompt for selection of the Non-Roll-Up mode
of operation. The Non-Roll-Up mode blanks the display and delays the weight display update until the
weight has stabilized or a three-second time delay has elapsed. A single moving segment is displayed
during this time delay. After pressing the HOLD/REL key, press the ZERO key to set the value to YES
or NO, then the HOLD/REL key to save the setting.
INHIBIT SERIAL DATA
The display will now indicate iSnd=. After pressing the HOLD/REL key, press the ZERO key to set
the value to NO. Press the HOLD/REL key to save the setting.
The display will display the software revision number then the gross weight. The setup and calibration
process has been completed and the indicator is ready to weigh. Place the test weight back on the
scale to verify calibration.
Make certain that all four (4) screws in the bottom of the CN20 enclosure have been tightened.
A summary of the setup and calibration steps is shown in Figure no. 6 to serve as a quick reference.
