adjust to 18.2ms. The
%' 0+ *
setting is especially useful when using the pulse output as a
ratemeter, however, if a ratemeter output is desired, the 4-20mA loop will provide better results. Dial
position #7 provides a customized pulse output setting initially set to
. , which can be edited for any
pulse width (max 999ms).
Note: If the pulse width exceeds the inverse of the number of requested output pulses per second,
the total display will indicate this error with an in the left most totalizer character during Run Mode .
When the is displayed, output pulses are being lost. Example: If the pulse width is set to (ms),
then the maximum number of pulses that may be outputted is two per second.
11.2 Pulse Output - Pulse Divider
Divides the pulse output by the displayed value. The divider is set by turning the
Number dial to the desired position. The dial positions allow several standard
pulse dividers as well as one customizable setting. The selected pulse divider is listed in the upper
display. The customized pulse divider setting is switch position #8 (initially set to
. ), and can be
edited for any value (max 9999).
12. Backlight Timer
Determines the length of time the backlight remains “ On ” when activated. Set by
turning the Number dial to the desired position. The dial positions allow several
standard timer values in seconds as well as one customizable setting. The selected timer value is
listed in seconds in the upper display. If the timer is set to
, the battery will last about two
months. This setting is not needed for DC powered units as the backlight is always on when DC
powered anyway. The customized backlight timer setting is switch position #9 (initially set to
. ), and
can be edited for any number of seconds (max 9999s).
Note: The backlight timer is only a timer. Even when disabled, the backlight may be used when a
magnet is located by the
Light
magnetic reed switch.
Note: The backlight is the highest current drawing component of the IT400 . Use it sparingly;
excessive use will quickly reduce the battery life (when running on the internal battery).
13. Power Mode
Sets the IT400 ’s internal power savings functions and the refresh rate. The power
mode is set by turning the Number dial to the desired position. Power modes
range from mode 1 (fastest refresh, shortest battery life) to mode 5 (slowest refresh, longest battery
life). The power mode is described in greater detail in the Power section of this manual.
Note: When power mode is set to 5, the datalogger activation timer period (
!
) will be rounded
down to the nearest even number.
