1. CALIBRATION KIT
Equipment required:
9Calibration kit ref: P01196770 including software and interface board
9Screwdrivers: Torx 4 mm or Posidriv, depending on date of manufacture
9Calibrator: Fluke 5500, Datron 9900 or equivalent
9Test leads
9Short cord or short circuit with 19 mm spacing
1.1 Getting started with CA 527x
Unplug the test leads.
1.1.1 Step 1
1.1.2 Step 2

2.3. COM port
Select the communication port: look for the COM port that corresponds to your USB cable.
Example: Windows XP config panel Æ System Hardware Æ Device manager Æ Ports
(COM and CPT). Search for CP210x in the list of COM ports. Select the
corresponding COM port in menu below.
Note : COMx searches automatically the COM corresponding to CP210x.
2.4. Reading the calibration data
After selecting the COMx, you are advised to read the data from the current calibration:
Select « Read_Ram ».

3. CALIBRATION
The CA 527x, MX 50xx, MTX 329X have manual settings.
3.1. Offset setting
Warning! The operations below must be carried out strictly in the following order.
1) Turn the multimeter OFF.
2) Short-circuit the VOLT and COM inputs.
3) Press the "MODE" and "HOLD" keys and hold them until step 5) below.
4) Set the multimeter to the V(AC+DC) position.
5) The display shows "CAL". Release « MODE » and « HOLD ».
6) Wait for XX s (LCD display counts down from XX to 0).
During calibration process, LCD displays:
Îautocal Volt « DC »
Îautocal Volt « AC + DC »
Îautocal Amp « DC»
Îautocal Amp « AC + DC »
CAL « OHM » ÎSelect the "OHM" function
CAL « CAPA » Îopen "DC" and select the "CAPA" function
7) Wait until the display shows "En0" then turn the CA527x / MX50xx / MTX 329x
multimeter off.
3.2. Slope settings or gains settings
*There is no order in respect to the setting of the slopes. It is possible to set
some or all ranges based on errors identified during product verification.
Refer to possible selections below:

English
12
1) Select (if this has not already been done previously) a function and its range
Ex.: VDC 600mV.
2) Press the yellow button "CAL Pentes / Slopes".
This opens the following menu.
3) Calibrate.
Note: R0 to R5 are the different ranges. The boxes to the right show the
relevant range for each instrument.
In this example: R0 = Voltmeter: 60mV, Ohmmeter: 600Ω,
Ammeter: 600μA, Capacitance: 600nF.
#Example : Function « Volt DC », « range 600mV » Æ R1
Press « CAL Pente: Slope »

English

13
Loop :
Check whether the "Input" set point is correct (e.g. range 600 mV =+500mV).
Apply the set point positive voltage.
Press the "READ val AD" (Input pos) button.
Apply the set point negative voltage.
Press the "READ val AD" (Input neg) button.
If the calculated slopes are correct (type table below), press the "WR Slope /
Slope".
Otherwise, check that V = V calibrator reference and there is no
communication problem.
The multimeter should now show an exact value (close to the set point of
the calibrator).
Go to next range.
Loop end.
In order to calibrate the range 600mV only, press "R1" and perform the loop
once. To calibrate all ranges, perform the loop with R0, R1, R2, R3, R4, R5.
Notes: For each Range, the program suggests a set point for calibration. This
setting can be changed. It is better to stay between 60 and 80% of the
range.
It is possible to change the AC/DC coupling. In order to prevent losing
a calibration after the instrument has been switched off, it is possible to
store the settings at all time with the button "MEM_RAM."
For a full calibration, choose next :
V(AC + DC) and do all ranges
A(DC) and do all ranges
next A(AC + DC) and do all ranges
next Ohm and do all ranges
next CAP and do all ranges
for TEMP : You must enter the ambient temperature at ± 0.5 ° C, and strt
“READ TEMP” after this “SET OFFSET”, otherwise do nothing.

3.3. Correction factor
For use only by SAV
1) In the "Function MENU" select the "Cor_AC" line.
2) Check whether the correction slopes have been refreshed.
3) Carry out a transfer using the "WR Slope/Pente" button.
3.4. Bandwidth Compensation
To calibrate the bandwidth, select:
1) Menu "Fr_Comp", "AC + DC" Bandwidth compensation.
Calibrator setup and calibration:
2) Frequency
CA 527x apply 2.5 kHz on range 600mV, and 3 kHz on ranges > 600 mV.
MX 50xx apply 5 kHz for all ranges.
3) Amplitude
Apply approx. 50% to 70% range (e. g. range 600mV Æ300mV).
4) Adjust the displayed value with the buttons "C7 to C0" (assets are marked).
Proceed starting with the largest available CX (MSB), press WrCAP to
validate, check the displayed value.
If the display is in excess, keep Cx ON, and carry on with Cx-1.
If the display is in default, turn Cx OFF, and carry on with Cx-1.
The optimum setting is approached by dichotomy.
Proceed this way with all Cx, keeping each time the setting that best
approaches the set point. Generally, at the end, the value must be within the
tolerance: Set point ± 0.5%.

English
17
17
4) At the end of the process, save the setting with the command "MEM_RAM" or
"Write to EEPROM mem."
5) Note: The program provides a starting configuration with all Cx OFF. After
the initialization, switching ON any Cx can only decrease the value. It is
possible to start with positions corresponding to the preceeding
adjustment. Please perform the Read_RAM command at beginning,
then enter the switch positions manually.

3.5. Misc. (Divers)
Select the language
Store / read the calibration data to / from a file and transfer to the CA 527x /
MX50xx / MTX 329x or to a computer.
3.6. READ
Here you can read some Multimeter data :
Read_LCD reads the value of the LCD primary display
Read_UC reads the RMS value supplied by the converter
Read_Bat reads the battery voltage
Read_Ram reads the calibration values

3.9. Running a remote command
To pilot the CA 527x, the MX 50xx or the MTX 329x manually, select a command in the list
below and press the "Command Î" button.
*Warning! For the "OHM / CAP / TEMP / DIODE / CONT" commands, the switch on
the instrument must be in the corresponding position.

English

4. STORING CALIBRATION DATA
Select the "Write mem to EEprom" command and press the "Command Î" button.
The calibration results are stored in the EEprom.
5. QUITTING THE PROGRAM
You can save your modifications on the EEprom :
When exiting the program, the language and the COM settings are memorized.
