FACTORY SERVICE CODE
0-250
Enter the Service Code for the desired operation.
RESTORE FACTORY DEFAULTS
Use the ! and @ keys to display COdE 66 and press P. The meter will flash
rESEt and then return to COdE 50. Press the P key to return to Display Mode.
This will overwrite all user settings with the factory settings. The only exception
is the User Mnemonics which retain their programmed values (see Code 69).
RESTORE FACTORY DEFAULTS (w/Units Mnemonics)
Same as Code 66, except the User Mnemonics are also returned to the factory
default settings (blank).
MODEL AND CODE VERSION
The meter will briefly display the model (P2S) on Line 1, and the current
firmware version (UEr x.xx) on Line 2, and then return to COdE 50.
METER CALIBRATION
NO INPUt AnLOut
The meter 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 meter
appears to be indicating incorrectly or inaccurately, refer to Troubleshooting
before attempting to calibrate the meter. 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 (APPLY) Scaling Style.
Preparation for Voltage Input Calibration
Warning: Input Calibration of this meter 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 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 meter. 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.
Input Calibration Procedure
1. After entering CodE 48, in Factory Service Operations, select the input
(0.020v or 0.20v) to be calibrated.
2. Press the P key until the desired range along with 2ER is indicated on Line 1
of the meter.
3. Apply the zero input limit of the range indicated on Line 1 of the meter.
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 on Line 1 of the meter.
7. Apply the signal level indicated on Line 1 of the meter.
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 the other Input Range if
calibration for the other range is desired.
Analog Output Card Calibration
Before starting, verify that a precision meter with an accuracy of 0.05% or
better (voltmeter for voltage output and/or current meter for current output) is
connected and ready. Using the chart below, step through the five selections to
be calibrated. At each prompt, use the PAX2S ! and @ keys to adjust the
output so that the external meter display matches the selection being calibrated.
When the external reading matches, or if the range is not being calibrated, press
the P key to advance to the next range. When all the desired ranges have been
calibrated, exit programming mode and remove the external meters.
