RESTORE FACTORY DEFAULTS
Use the ! and @ keys to display COdE 66 and press
P. The controller will
flash rSEt and then return to COdE 50. This will overwrite all user settings with
the factory settings.
MODEL AND CODE VERSION
The controller will briefly display the model (P2C) on Line 1, and the current
firmware version (UEr x.xx) on Line 2, and then return to COdE 50.
CONTROLLER CALIBRATION
NO Curr UoLt rES
tc ICE rtd AnLG
The controller has been fully calibrated at the factory. Scaling to convert the
input signal to a desired display value is performed in Input Parameters. If the
controller appears to be indicating incorrectly or inaccurately, refer to
Troubleshooting before attempting to calibrate the controller. When recalibration
is required (generally every 2 years), it should only be performed by qualified
technicians using appropriate equipment. Calibration does not change any user
programmed parameters. However, it will affect the accuracy of the input signal
and the values previously stored using the Apply (APLY) Scaling Style.
Preparation for Current, Volt, and Ohm Input Calibration
Warning: Input Calibration of this controller requires a signal source
capable of producing a signal greater than or equal to the range
being calibrated with an accuracy of 0.01% or better.
Before starting, verify that the Input Range, T/V, and Excitation Jumper is set
for the range to be calibrated. Verify that the precision signal source is connected
and ready. Allow a 30 minute warm-up period before calibrating the controller.
Selecting NO at any calibration step, will cause the unit to maintain the existing
calibration parameters for that step. Selecting YES and pressing the
P key will
cause the unit to store new calibration settings for the range selected. Pressing
D at any time will exit programming mode, but any range that has been
calibrated will maintain the new settings.
Current, Volt and Ohm Calibration Procedure
1. After entering CodE 48, select the input signal type (Curr, UoLt, rES) to be
calibrated.
2. Press the
P key until the desired range along with 2ER is displayed in the Line
2 units mnemonic.
3. Apply the zero input limit of the range indicated on Line 1 of the controller.
4. Press ! to select YES.
5. Press
P. Display will indicate ---- on Line 2 as the unit reads and stores the
new calibration parameter.
6. Display will indicate the desired range along with FUL in the Line 2 units
mnemonic
7. Apply the signal level indicated on Line 1 of the controller.
8. Press ! to select YES.
9. Press
P. Display will indicate ---- on Line 2 as the unit reads and stores the
new calibration parameter.
10. Repeat Preparation and Calibration Procedure for each Input Range to be
calibrated.
