4.24 Configuration Menu [CONFIG]
The Configuration Menu contains all of the general user settings:
Entry Lock
This function allows the user to lock out unauthorized
tampering with instrument settings. All settings may be
viewed while the instrument is locked, but they cannot be
modified. The Entry Lock feature is a toggle-type setting;
that is, entering the correct code will lock the transmitter and
entering the correct code again will unlock it. The code is
preset at a fixed value. Press ENTER to initiate user entry
mode and the first digit will flash. Use arrow keys to modify
value.
See end of manual for the Q45C2 lock/unlock
code.
Press ENTER to toggle lock setting once code is
correct. Incorrect codes do not change state of lock
condition.
Set 4 mA
Set 20 mA
These functions set the main 4 and 20 mA current loop
output points for the transmitter. The units displayed depend
on the selection made in the CONFIG menu for Iout #1
Mode. Also, when the Relay Option Board is installed, the
units will also display #
1 or #2
– since there are actually two
analog outputs present in this version.
The value stored for the 4 mA point may be higher or lower
than the value stored for the 20 mA point. The entry values
are limited to values within the range specified in “Set
Range”, and the 4 mA and the 20 mA point must be
separated by at least 1% of this range Use the LEFT arrow
key to select the first digit to be modified. Then use the UP
and LEFT arrow keys to select the desired numerical value.
Press ENTER to store the new value.
Set Delay
The delay function sets the amount of damping on the
instrument. This function allows the user to apply a first
order time delay function to the conductivity measurements
being made. Both the display and the output value are
affected by the degree of damping. Functions such as
calibration are not affected by this parameter. The
calibration routines contain their own filtering and stability
monitoring functions to minimize the calibration timing.
Press ENTER to initiate user entry mode, and the value will
flash. Use the arrow keys to modify value; range is 0.1 to
9.9 minutes. Press ENTER to store the new value.
