Page 20: Measuring Temperature
Measuring temperature Measuring temperature with non-intelligent sensors The DTI050 supports measuring temperature with non-intelligent TC, RTD and Thermistor sensors. Table 1 lists the available thermocouple types while table 2 lists the available RTD types.

Page 22: Measuring Temperature With Intelligent Sensors
Measuring temperature with intelligent sensors For intelligent sensors simply plug the sensor into the DTI050 and it will automatically detect the sensor and display it’s serial number on the screen. All of the sensors parameters can be reviewed in the configuration modes (see section 3.2.1). -
Page 23: Remote Operation
Remote operation Remote interface The DTI050 can be remotely controlled using a PC terminal, or by a computer program running the indicator in an automated system. It uses an RS232 serial port connection for remote operation. With this connection the user can write programs on the PC with Windows languages like Visual Basic to operate the indicator, or use a Windows terminal program, such as Hyper Terminal, to enter single commands. -
Page 24: Changing Between Remote And Local Operation
Enter the above information for port settings. Select ASCII setup from File/Properties/Settings and mark these choices: • Echo typed characters locally • Wrap lines that exceed terminal width Select Ok To see if the port works enter *IDN?. This command will return information on the DTI050. -
Page 25: Using Commands
Using commands 5.4.1 Command types Refer to the section on Remote commands for all available commands. The indicator may be controlled using commands and queries. All commands may be entered using upper or lower case. The commands are divided into the following categories: Indicator commands Only the indicator uses these commands. -
Page 26: Character Processing
Floating numbers have up to 15 significant figures and exponents. For example: P_CVD_A? returns 3.908300E-03 Character response data (CRD) Data returned as keywords. For example: RTD_TYPE? returns PT385_100 Indefinite ASCII (IAD) Any ASCII characters followed by a terminator. For example: *IDN? returns AMETEK, DTI050, 1234567, 1.00 31-08-2006 125821... -
Page 27: Indicator Status
5.4.4 Indicator status Error queue If an error occurs due to invalid input or buffer overflow, its error code is sent to the error queue. The error code can be read from the queue with the command FAULT?. The error queue holds 15 error codes. When it is empty, FAULT? returns 0. - Page 28 DTI050 commands, cont. Command Description LOCKOUT Locks out the keypad when the DTI050 is in remote mode. Returns the voltage (in mV) that the DTI050 is reading when in TC. OHMS? Returns the resistance the DTI050 is reading when in RTD. REMOTE Puts the DTI050 in remote.
- Page 29 Parameter units (table 5) Units Meaning Current in amperes. Voltage in volts. Temperature in Celsius. Temperature in Fahrenheit. Temperature in Kelvin. Resistance in Ohms. Turn something on. Turn something off. Time in seconds . Error codes (table 6) Error number Error description A non-numeric entry was received where it should be a numeric entry.
-
Page 30: Entering Commands
Clears the error queue. Also terminates all pending operations. When writing programs, use before each procedure to avoid buffer overflow. *IDN? Returns the manufacturer, model number, serial number and firmware revision of the Indicator. For example: *IDN? will return AMETEK,DTI050,0000123,1.00 31-08-2006 125821... -
Page 31: Dti050 Commands
5.6.2 DTI050 commands FAULT? Returns the error code number of an error that has occurred. The command may be entered when the previous command did not do what it was meant to For example, if an invalid command was sent, FAULT? would return: 110 which is the code number for an unknown command being received. - Page 32 LOCKOUT Sending this command sets the lockout state, when the DTI050 is in REMOTE or goes to remote it prohibits use of the keypad completely. The lockout state can only be cleared by sending the LOCAL command. Returns the raw voltage value from a thermocouple. For example: If when measuring a type J at 0 degrees cel sending MV? would return 0.000000E+00, MV .
- Page 33 RTD_TYPE? Returns the RTD type. For example: If the RTD type is PT100, α=385, ITS-90, RTD_TYPE? Will return P100(90)385. TC_TYPE Sets the TC type. The following is a list of TC types the way they should be entered after the command: For example: TC_TYPE J sets the TC type to J TC_TYPE?
- Page 34 TEMP_RES Sets the resolution for all DTI050 temperature readings. For example: TEMP_RES 3 would set the resolution of the temperature display to 1 thousandth. TEMP_RES? Returns the number of digits to the right of the decimal point. For example: If the resolution is 1 thousandth, TEMP_RES? will return 3. TEMP_UNIT This command is used to change the temperature unit used, when measuring temperature.
