Instructions

Calibration Preparation

Gauges are calibrated at the factory using equipment traceable to NIST.

There is no need to calibrate the gauge before putting it into service.

Calibration should only be performed by qualified individuals using

appropriate calibration standards and procedures.

Gauges can be returned to factory for certified recalibration and

repairs. NIST traceability is available.

Calibration intervals depend on your quality control program

requirements and as-found data. Many customers calibrate their

equipment annually.

The calibration equipment should be at least four times more accu-

rate than the gauge being calibrated.

The calibration system must be able to generate and measure pres-

sure and/or vacuum over the full range of the gauge.

A vacuum pump able to produce a vacuum of 100 microns (0.1

torr or 100 millitorr) or lower is required for vacuum and absolute

gauges.

Use a stable DC power supply and an accurate mA meter to cali-

brate loop powered transmitters.

Allow the gauge to equalize to normal room temperature for at least

20 minutes before calibration.

Enter Calibration Pass Code

The gauge must be powered by a 10-32 VDC power supply during

calibration.

With the gauge powered up, press and hold the t

and TEST buttons.

Then press the SEL button to enter the Calibration

Mode.

Release all buttons when the display indicates

CAL

. The firmware version is also displayed.

The display prompts for entry of the calibration

pass code (CALPC), with the first underscore

blinking. To enter the 4 digit pass code, see the

Enter Configuration Pass Code section. Note that

it is possible to change the default 3510 value.

Calibration Mode

The gauge enters and remains in the Calibration Mode until

restarted manually or power is removed.

The display will then indicate the currently applied pressure in the

engineering units selected in gauge configuration.

Button Operation

Each time the s or t button is pressed and released quickly, a

small change is made to the digitized pressure signal.

It may take more than one of these small changes to result in a

single digit change on the display.

To make larger changes, press and hold the appropriate button.

After about one second, the display will begin to change continu-

ously. Release the button to stop.

Then make fine adjustments by pressing and quickly releasing the

s or t buttons as previously described.

The SEL button is used to select LCAL (4 mA calibration), HCAL

(20 mA calibration), or CAL (pressure calibration).

If the SEL button is depressed for longer than 2 seconds, the

display will change to indicate – – – – , and the gauge will exit the

Calibration Mode when the button is released.

Pressure Calibration

The pressure calibration procedure simultaneously adjusts both the

display indication and the loop current to correspond to the actual

applied pressure.

Press and release the SEL button until the display

briefly indicates CAL.

Zero Calibration

Apply zero pressure.

The lower display segments will alternate

between CAL and ZERO.

Use the s or t buttons to adjust the display

to zero.

Span Calibration

Apply full scale pressure.

The lower display segments will alternate

between CAL and +SPAN.

Use the s or t buttons to adjust the display to

match the calibrator's pressure reading.

Mid Point Calibration

Apply 50% of full scale pressure.

The lower display segments will alternate

0 . 0

between CAL and +MID.

Use the s or t buttons to adjust the display to

match the calibrator's pressure reading.

Negative Mid Point Calibration

CALPC

This applies only to bipolar ranges that use the

±15 psig sensor.

Apply 50% full scale negative pressure (50%

vacuum).

The lower display segments will alternate

between CAL and –MID.

Use the s or t buttons to adjust the display to

match the calibrator's pressure reading.

To store the calibration parameters and exit the

Calibration Mode, press and hold the SEL button

until the display indicates – – – – . The gauge

will restart.

Verify the pressure indications at 0%, 25%, 50%,

75% and 100% of full range of the gauge.

Loop Current Calibration

Loop current calibration coordinates the loop current to the display

indication, and is performed independently of applied pressure. It

requires a direct physical measurement of the loop current. See

wiring diagrams on page 2.

4 mA Loop Current

Press and release the SEL button until the display

briefly indicates LCAL.

Note: If the SEL button is depressed for lon-

ger than 2 seconds, the gauge will exit the

Calibration Mode.

The upper display will indicate the pre-configured

pressure corresponding to a 4 mA loop current.

The lower display segments will alternate

between CAL and 4 MA.

Use the s or t buttons to adjust the actual loop

current to 4 mA.

20 mA Loop Current

Press and release the SEL button until the display

briefly indicates HCAL.

Note: If the SEL button is depressed for lon-

ger than 2 seconds, the gauge will exit the

Calibration Mode.

The upper display will indicate the pre-configured

pressure corresponding to a 20 mA loop current.

The lower display segments will alternate

between CAL and 20 MA.

Use the s or t buttons to adjust the actual loop

current to 20 mA.

User-Defined Pass Code Configuration

The factory default 3510 pass code may be changed to a differ-

ent value.

Configuration Pass Code

With the unit on, press and hold the s and TEST buttons and

then press the SEL button. Release all buttons when the display

indicates CFG.

Calibration Pass Code

With the unit on, press and hold the t and TEST buttons and

then press the SEL button. Release all buttons when the display

indicates CAL.

Test Function Pass Code (if enabled)

With the unit on,, press and hold the TEST button and press the

SEL button. Release both buttons when the upper display indicates

– – – – .

Change Pass Code Mode

Before the unit enters the view or change pass code mode, the

display initially indicates _ _ _ _ with the first underscore blinking,

and with CFGPC, CALPC, or TSTPC on the lower display.

The gauge will revert to normal operation if no buttons are operated

for approximately 15 seconds. Press and release the SEL button

without entering any pass code characters to exit.

Enter access code 1220:

Use the s and t buttons to set the left-most digit to 1.

Press and release the SEL button to index to the next position. The

1 will remain, and the second position will be blinking.

Use the s and t buttons to select 2.

Press and release the SEL button to index to the next position. 1 2

will remain, and the third position will be blinking.

Use the s and t buttons to select 2.

Press and release the SEL button to index to the next position. 1 2

2 will remain, and the fourth position will be blinking.

Use the s and t buttons to select 0.

Press and release the SEL button to proceed.

Note: If an incorrect access code was entered, the gauge will return

to the start of the access code entry sequence.

Change Pass Code

Once the access code has been entered correctly, the display

will indicate the existing user-defined pass code with CFGPC,

CALPC, or TSTPC on the lower display.

Press the s or t button to select the first character of the new

pass code.

When the correct first character is being displayed, press and

release the SEL button to proceed to the next pass code character.

Repeat above until the entire pass code is complete.

To exit the User-Defined Pass Code change mode, press and hold

the SEL button until the gauge restarts.
