1. Introduction

The CONDEC 3030 is designed to be a simple to use yet very versatile pressure calibrator. Its two internal pressure sensors, P1 and P2 ports, combined with inputs for mA, voltage, switch contacts and an RTD probe allow the CONDEC 3030 to calibrate virtually any pressure device. An external pressure module option allows an even wider range of pressure calibration options including absolute and differential.

ments 4 Backlight Key This key is used to turn the backlight on and off

Note: When the calibrator is turned on by pressing the ON/OFF key, it will go through a short startup self-check routine. During that routine, the display shows the current firmware revision level, auto shutdown status and the ranges of the 2 internal pressure sensors. The calibrator requires a maximum of 5 minutes warm-up to rated accuracy. Large changes in ambient temperature may require a longer warm-up period. See section 2.3 for instructions on zeroing the pressure sensor displays. Pressure ranges should be zeroed each time the calibrator is started.

2.1 Calibrator Display

The Calibrator Display consists of two regions: The menu bar (located along the bottom of the screen) is used to access a menu system. The main display (the rest) consists of up to three process measurement sub-regions. These sub-regions will henceforth be referred to as the UPPER, MIDDLE and LOWER displays. Figure 3 shows the location of the different display fields while table 3 describes them.

2.1.1 Main Menu Functionality

There are three options on the Main Menu, CONFIG, {current display} and MORE. The Main Menu is home for the menu display.

2.1.1.1 Setting the Current Display

The current display is indicated by the center option on the Main Menu, pressing the F2 key will toggle the current display.

2.1.1.2 Setting Current Display Parameters

To set the parameters of the current display use the CONFIG option to get to the Display Configuration Menu.

Here the SELECT option will toggle through the choices for each parameter. The first parameter is MODE. Since voltage, current and switch test modes all use the same jacks, two of these functions cannot be used concurrently. The ability to select certain functions is limited based on what is already selected in another active display. The NEXT option is used to change to the second parameter. Only RTD and Pressure modes have a second parameter, RTDs can be read in Celsius or Fahrenheit and Pressures can be read in 11 engineering units.

With a single display the following modes are available: P[1] = Pressure on left side sensor. P[2] = Pressure on right side sensor. [EXT] = Pressure with external pressure module. P[1] ST = Switch Test with left side sensor. P[2] ST = Switch Test with right side sensor. [EXT] ST = Switch Test with external pressure module. mA = Milliamps measure without loop power. mA LOOP = Milliamps measure with loop power. VOLTS = Voltage Measure. RTD = RTD Temperature Measurement (if a probe is connected). The following table shows which functions are available concurrently. An X in a column indicates that the mode in the current display will

not be available for selection if the mode in that row is in use in any other active display.

OTHER DISPLAYS

2.1.1.3 Accessing Other Menus

Use the MORE option on the Main Menu to access the other menu functions.

Figure 4 - Menu Map

2.2 Using the Backlight

The backlight is controlled by the dedicated backlight key. It toggles on and off when the key is pressed; this is one of the few functions that cannot be controlled by the serial interface. There are no user configuration settings for the backlight.

2.3 Using the Zero Function

When the ZERO KEY is pressed, the calibrator will zero the current display if a pressure mode is selected, and the pressure is within the zero limit. The zero limits are within 5% of the full scale range of the selected sensor. If the display indicates "OL ," the zero function will not operate."

2.3.1 Internal Sensor and Pressure Module (non-absolute)

When a sensor or module is selected on the current display and the ZERO KEY is pressed the calibrator subtracts the current reading from the output. The zero limits are within 5% of the full scale range of the selected sensor. If the display indicates "OL ," the zero function will not operate.

2.3.2 Absolute Internal Sensor or Absolute Pressure Module

When an absolute pressure module is selected on the current display and the ZERO KEY is pressed the calibrator prompts the user to enter the barometric reference pressure. This is done using the arrow keys (F2 and F3 Keys). The sensor port should be open (vented) to atmosphere while performing this procedure.

2.4 Other Menu Controlled Functions

There are eight 'sub-main' menus that can be accessed through the MORE option of the Main Menu. A 'sub-main' menu contains three options. The first option is unique to the function. The second and third options of a 'sub-main' menu are always the same. The NEXT option leads to the next 'sub-main' menu and the DONE option returns home . For the last 'sub-main' menu the NEXT option wraps around to home. See Figure 4 for a detailed mapping of the menu structure.

A note on naming convention:

If a 'sub-main' menu has subordinate menus, it will henceforth be referred to as { function} Main Menu. E.g. the display contrast submain menu will be called the Contrast Main Menu. If not it will be called the { function} menu.

2.4.1 Setting the Contrast

From the Contrast Main Menu choose the CONTRAST option to access the Contrast Adjustment Menu.

Use the arrow keys to adjust the display contrast to the desired level and then use the CONTRAST DONE option to return home.

2.4.2 Locking and Unlocking Configurations

Use the LOCK CFG or UNLOCK CFG option of the Configuration Lock Menu to lock or unlock the display configuration.

When the LOCK CFG option is chosen the menu display returns home and the CONFIG option on the Main Menu indicates that it is locked. Also all menus are locked out with the exception of the Contrast Adjustment menus and the Configuration Lock Menu. When the UNLOCK CFG option is chosen the configuration is unlocked and the menu display continues to the next sub-main menu.

2.4.3 Saving and Recalling Setups

The calibrator will automatically save the current set-up for recall at power-up. Additionally 5 set-ups can be accessed through the SETUPS menu. Select the SETUPS option from the Setups Main Menu.

Choose SAVE to save a set-up , RECALL to recall the set-up, or DONE to do nothing and return home.

If SAVE or RECALL is selected use the arrow keys to select the setup location. Then use the save option to store the current set-up into the selected location or the recall option to recall the set-up stored in the selected location. The display menu will automatically go home.

2.4.4 Setting AutoShut-off Parameters

The calibrator can be set to automatically shut-off after a selected number of minutes; this function can also be disabled. To set the auto shut off parameters select the AUTO OFF option on the Auto Shut Off Main Menu.

Use the arrow keys to select the number of minutes before the calibrator turns off or disable auto shut-off by scrolling all the way down.

Use the AUTO OFF DONE option to set the parameters and return home. The auto shut off time is reset whenever a key is pressed.

2.4.5 Activating and Deactivating a Display

Use the DISPLAY option on the Display Selection Main Menu to access the Display Activation Menu.

The { function} option can be used to select which display to act upon. The ON/OFF option turns the selected display on or off. The selected display and current on/off state are displayed in the lower display.

Use the DONE option to save the changes and return home. When a display is deactivated its configuration is retained. When the display is activated its configuration is checked against the configurations of the other currently active displays, if the configurations are in conflict the recalled display's configuration is modified to avoid the conflict. If all three displays are deactivated the LOWER display will come on automatically

2.4.6 Setting the RTD probe type

Use the PROBE TYPE option of the RTD Probe Type main menu to access the RTD Probe selection menu.

There are four probe types to select from P100-385, P100-392, P100JIS and CUSTOM. Use the SELECT option to select the desired probe type and the DONE option to store the change and return home.

Note: The default probe type is PT100-385.

2.4.7 Damping

Damping can be turned ON or OFF using the Damping menu selection. When damping is ON, the calibrator displays an running average reading of ten measurements. The calibrator makes approximately 3 readings per second.

3. Measuring Pressure

To measure pressure, connect the calibrator using an appropriate fitting. Choose a pressure setting for the display being used. The calibrator is equipped with two internal sensors and many optional external sensors (EPMs) are available. Be sure to choose the sensor based on working pressures and accuracy.

Note:

Pressure sensors may be damaged and/or personnel injury may occur due to improper application of pressure. Please refer to the table of ranges and resolutions at the back of this manual for information on overpressure and burst pressure ratings. Vacuum should not be applied to any gauge pressure sensor.
