Date and Time
setup menu (54): Use this menu to set the date and time in the flowmeter’s internal
clock. The time is expressed in military time (24-hour format), and the date is in the month-day-year
format (Figure 3.13-I, below). If you are NOT using UltraScan, set the time and date as follows:
a.
Perform a Master Erase on the flowmeter according to
Section 5.2 (page 45)
.
b.
Reconfigure the flowmeter, and access Menu 54.
Performing a Master Erase and reconfiguring the flowmeter prior to changing
date or time prevents possible data corruption.
c.
Press
ENTER
, and prompts are displayed, requesting entries for month, day, year and hour,
minute, second (Figure 3.13-J, below). Press
ENTER
after EACH entry.
d.

3.14 Additional Setup Menus Within the 4-20 mA Submenu
*Not included in the Quick Setup configuration
Within the
4-20mA
submenu is the
Current Loop Group
menu (56)
(Figure 3.14-A, page 26)
, which
contains 3 setup menus:
Span, Cal., Test
(menus 57 through 59).
The 4-20 mA current loop is factory calibrated and should not require field calibration prior to use. If
calibration and testing should become necessary, complete the following steps:
1.
Connect a milliammeter to the input (IN) and output (OUT) terminals of the current loop module.
2.
Access Menu 58
(Figure 3.14-B, page 26)
.
3.
Press the
RIGHT
or
LEFT ARROWS
to adjust the 4 mA set point until the value reads exactly 4.00
mA on the milliammeter. Every 2 presses of the arrow key adjusts the calibration approximately .01
mA.
