Calibration Setup

Requirements

For the calibration test you need:

A high accuracy voltmeter;

A PTC04 calibration board (PTC04-DB-Calib

Supporting daughter board for calibration of PTC04

programmer).

The software has an automatic calibration feature. For this you

need a Keithley 2000 or an Agilent (HP) 34401A multimeter. The

Agilent 34401A multimeter is supported in the PTC04 User

Interface revision 1.35 or higher.

If you use the automatic calibration feature, all channels will be

calibrated with the multimeter as reference meter.

If a manual approach is used, only the first sensing line is

calibrated with the external reference meter. For all the other

channels the first sensing line will be used as reference.

IMPORTANT NOTE:

Although the firmware version of the PTC04 has no impact on

the quality of the PTC04 calibration, it is advised to upload the

ptc04_mlx90251_firmware.hex or

ptc04_mlx90316_firmware.hex firmware to the PTC04 before

replacing the daughter board of the PTC04 with the PTC04-DB-

Calibration.

Figure 2: Connections

Because: some firmware versions have a pre-configuration of the relays

on the daughter board that does not match with the relay configuration

of the PTC04-DB-Calibration.

Connections

1. Replace the daughter board of the PTC04 with the calibration board:

Remove the cover of the PTC-04;

Remove the PTC04 Daughter Board of the MLX device;

Plug in the PTC04 Calibration Board;

2. Connect the reference voltmeter to the BNC connector or 4mm PCB

Plugs (Both connections are in parallel);

3. Connect the RS232 or USB cable to the PTC04 and the PC;

4. Connect the RS232 of the multimeter to the PC;

5. Connect the power supply of the PTC04.

RS232 settings

The RS232 communication of the multimeter has to be configured as follows:

Keithley 2000 multimeter Agilent (HP) 34401A multimeter

BAUD: 19.2 K BAUD: 9600 BAUD: 4800

FLOW: NONE PARITY: EVEN: 7BITS OR PARITY: NONE: 8BITS

TX TERM: CR LANGUAGE: SCPI LANGUAGE: SCPI

For configuration instructions, please consult the user’s manual of your multimeter.

All other settings are set by the software via RS232 commands.

Check Calibration of the programmer

Now your PTC programmer is connected and you can start-up the MPT software.

When the software is started, double click on PTC-04 in the UI modules list

or select from the menu “Tools Search devices All”

Figure 4: Melexis Programmable Toolbox.

The software will search for all available devices. When a PTC programmer is found it will be initialized. Otherwise the

software will display a notification that no PTC devices have been found and will enter the disconnected state.

If the connection failed, check the serial cable and

power connection or change the settings if you have

connected the programmer to a different serial port.

To open the Calibration test module, press the button

Calibrate on the PTC04 User Interface.

Figure 5: User Interface PTC-04.

Calibration check

This module of the PTC-04 User Interface is used to verify if the calibration parameters of the programmer are within

tolerance. The software will check the power drivers (DAC) and the voltmeter (ADC), and compare its results with the

calibration parameters. If the calibration parameters are out of tolerance, they can be corrected.

Before starting the calibration check

It is advised to leave the programmer powered up for minimum 30 to 60 minutes before starting the

calibration. For the accuracy of the calibration, it is important that the programmer is at operating

temperature.

Very important: do not connect any load on the connectors of the calibration board during the calibration

check. Any additional load will corrupt the calibration parameters and lead to an unusable set-up. If this

should happen, restart the calibrate check without a load connected to the programmer.

If you have a Keithley 2000 or an Agilent (HP) 34401A Multimeter, select the correct multimeter from the

selection box (1) before you start the calibration check. The multimeter has to be connected to the PC used

for the calibration check. The default COM-port for the multimeter is COM2. One can change the selected

COM-port in the “COM port #” Edit-box (2).

Figure 6: Calibration Check.

Press Verify Calibration to start the calibration.

You are reminded to leave your PTC04 powered up for minimum 30 to 60 minutes before starting the calibration.

Figure 7: Start Check?

Press yes to continue.

If you don’t use a Keithley 2000 or Agilent 34401A multi meter, you have to use a high accuracy voltmeter. The

accuracy of the calibration depends on the precision of the voltmeter and the number of digits entered. With a

manual voltmeter, the program will start with calibrating the internal voltmeter which will be used to check the

PTC04 programmer.

Figure 8: Proceed Check?

Press yes to continue.

At this stage the software will check if the calibration board and, if selected, the Keithley 2000 or Agilent 34401A

Multimeter are connected. If the calibration board is not detected, a message is shown.

Figure 9: Check setup

If the setup is not complete, press No, switch of the programmer, check your setup and restart the

program.

Manual voltmeter

If the Keithley 2000 or Agilent 34401A multimeter feature is not selected the program will ask you to put in a few

values from your voltmeter manually. These are used to calibrate the first sensing line of the PTC-04. This sensing line

will be used as reference meter for the calibration check.

Note: the accuracy of the calibration depends on the precision of the voltmeter and the number of digits you enter.

Figure 10: Manual calibration internal reference meter.

Press OK to continue.

For the calibration of the internal reference meter, two series of 32 values are required. Once the internal reference

meter is calibrated the software will continue with the calibration check.

Note: the decimal separator of the software is “.” not “,”. If one uses a “,” as decimal separator, the calculated

parameters will be incorrect.

Figure 11: Input Box Manual Voltmeter.

Insert the value from the voltmeter in volt [V] and press OK.

Note: If you entered a wrong value, press Cancel. Two error messages are shown.

Figure 12: Check Measuring line 1 Failed

Figure 13: The calibration check has been cancelled.

Press OK on both messages to continue.

Now the calibration check is terminated, you can restart the calibration check.

The calibration check

Now the calibration software will perform a number of measurements on all the ADC and DAC channels of the

programmer. This can take several minutes. At the end of the calibration check the program verifies if a correction of

the calibration parameters is needed.

Figure 14: Calibration Check

There are three possible outcomes

1. The program notifies you that the current calibration is out of tolerance and ask you if you want to corrected the

calibration parameters or not.

Figure 15: Calibrate?

If you press yes, the new calibration parameters are written into the PTC04.

If you press no, there are no modifications done.

2. The program notifies you that the current calibration is within tolerance! No Correction of the calibration

parameters (Calibration) is needed.

Figure 16: Calibrate Anyway?

If no calibration is needed you can still choose to calibrate or not.

If you press yes, the new calibration parameters are written into the PTC04.

If you press no, there are no modifications done.

3. At the end of the calibration, the software verifies if the programmer was at temperature when the calibration

started. If the programmer was not at temperature, the following message is given.

Figure 17: Programmer is not at temperature.

It is advised not to calibrate (store the new calibration parameters in the programmer) when the programmer is not

at operating temperature. This is important for the accuracy of the PTC04 programmer.

If you press yes, the new calibration parameters are written into the PTC04.

If you press no, there are no modifications done.
