SAGEON PSMC I PRODUCT MANUAL
PM990-2999-00, Rev 5
3-12
Note:
At installation time perform steps 1 to 6 with the input leads shorted. Each channel
should display a value close to zero. Whether it does or not, calibrate the value for
zero with its inputs shorted. Doing so fixes the proper offset values into memory.
Once these steps are complete connect the inputs to their respective sources, repeat
steps 1 to 6 and adjust for the proper levels.
Calibrate Zero Procedure
1. Enter the “
Calibrate Zero
” menu from the
Configure
menu by Pressing “
Select
”, then
press “
Next
” until the
Calibrate Zero
menu appears, then press “
Select
” again to access
the first channel:
PLANT VOLTAGE
READING: (present value)
2. Short the Plant Voltage sense leads together at the measurement point; the reading will
show the zero offset value.
3. Press “
Select
” again, and the SAGEON PSMC I will prompt:
INPUT SHORTED?
CONFIRM? NO
4. Verify proper shorting of the input leads then press “
Next
” or “
Previous
” to toggle the
input to “
YES
”
5. Press “
Select
” again and the SAGEON PSMC I will zero the channel and return to the
initial display showing the offset as zero:
PLANT VOLTAGE
READING: 0.00
6. Only those analog channels that were enabled in the Enable Channels menu will appear in
sequence. Press “
Next
” to reach the next analog channel; repeat this procedure to zero all
the analog channels. Shunt channels are displayed in millivolts (mV) and temps are
displayed in degrees F.
Note:
The temperature sensors by construction do not support shorting at the measurement
point. These channels can only be zeroed at the SAGEON PSMC I input when the
standard sensor and cable assembly are disconnected. In cases where an extension
cable was necessary the user can zero out the extension cable before connection to the
actual sensor wiring. BE SURE to short only the
SIG
and
RTN
leads.
When all the analog channels have been zeroed, leave the sense leads open to prepare for the
Calibrate Gain procedure. Press “
Escape
” to return to the initial “
Calibrate Zero
” menu.
Use “
Next
” or “
Previous
” to reach other Configure sub-menus, or “
Escape
” again to return
to the Save Configurations menu.
