F0101.EPS

䊏 Using the Transmitter Zero-adjustment

Screw

Before using the zero-adjustment screw outside the transmitter case, confirm the following.

• Ext SW mode must be ENABLE. See Subsection

2.3.3 (17) for the setting procedure.

• Use a slotted screwdriver to turn the zero-adjustment screw. Turn the screw clockwise to increase the output or counterclockwise to decrease the output, the zero point adjustment can be adjusted with a resolution of 0.01% of the setting range.

The degree of zero adjustments varies with the screw turning speed. Therefore, turn the screw slowly for fine adjustment and quickly for coarse adjustment.

䊏 Using the HART Communicator

Zero point can be adjusted by simple key operation of the HART Communicator.

Select parameter Zero Trim, and press the OK (F4) key twice. The zero point will be adjusted automatically to the output signal 0% (4 mA DC). Confirm that the setting value displayed for the parameter % rnge is 0.0% before pressing the OK (F4) key. See Subsection for HART Communicator operating procedures.

1.1 Zero Point Adjustment

The DPharp supports several adjustment methods. Select the method best suited for conditions matching

the state of the site. Note that output signal can be checked by HART

Communicator.

Adjustment Method

Zero adjustment using the HART Communicator

Zero adjustment using the external zeroadjustment screw

Set the present input to 0%. P.1-2 ‘Zero trim’

Adjust output to the reference value obtained using other means. P.1-2 ‘Lower sensor trim’

Adjust zero point using the zeroadjustment screw on the transmitter. This permits zero adjustment without using the HART Communicator. Accurately adjust the output current to 4mA DC or other target output value using an ammeter that accurately reads output currents.

Description

Adjust for 0% output at input level of 0%.

If the input level cannot easily be made 0% (because of tank level, etc.), adjust output to the reference value obtained using other means, such as a glass gauge.

T0101.EPS

CAUTION

Do not turn off the power to the transmitter immediately after a zero adjustment. Powering off within 30 seconds after a zero adjustment will return the adjustment back to the previous settings.

1.1.2 Using the Transmitter Zero-adjustment Screw

Turn the zero-adjustment screw on the outside of the transmitter case using a slotted screwdriver. Turn the screw to the right to increase the zero point or to the left to decrease the zero output; the zero adjusts in increments of 0.01% of the range setting.

Note that the amount of adjustment to the zero point changes according to the speed at which the screw is turned. To make fine adjustments, turn the screw slowly; to make coarse adjustments, turn the screw quickly.

Note: When a zero point adjustment has been made do not turn of

the transmitter less than 30 seconds after adjustment.

1.2.2 Setting the Range Using the Rangesetting Switch

With actual pressure(s) being applied to the transmitter, the range-setting switch (push-button) attached to the integral indicator plate and the external zero-adjustment screw allow users to change the lower- and upper-range values for the measurement range (LRV and URV) without the use of a HART Communicator. However, a change in the display settings (scale range and engineering unit) for the integral indicator requires a HART Communicator.

Follow the procedure below to change the LRV and URV settings.

Example: Rerange LRV to 0 and HRV to 20 kPa.

1) Connect the transmitter and allow them to warm up

for at least five minutes.

2) Press the range-setting push-button.

The integral indicator then displays LSET.

3) Apply a pressure of 0 kPa (atmospheric pressure) to

the high-pressure side of the transmitter.

4) Turn the external zero-adjustment screw (either in

the output-increase or -decrease direction). The integral indicator displays the output signal (in

(Note 2)

%).

5) Adjust the output signal to 0% (1 V DC) by

rotating the external zero-adjustment screw. Doing so completes the LRV setting.

6) Press the range-setting pushbutton.

The integral indicator then displays USET.

7) Apply a pressure of 20 kPa to the high-pressure

side of the transmitter.

(Note 1)

8) Turn the external zero-adjustment screw (either in

the output-increase or -decrease direction). The integral indicator displays the output signal (in

(Note 2)

%).

9) Adjust the output signal to 100% (5 V DC) by

rotating the external zero-adjustment screw. Doing so completes the URV setting.

10) Press the range-setting pushbutton.

The transmitter then switches back to the normal operation mode while maintaining the measurement range at 0 to 20 kPa.

Note 1: Wait until the pressure inside the pressure-detector section

has stabilized before proceeding to the next step.

Note 2: If the pressure applied to the transmitter exceeds the

previous LRV (or URV) , the integral indicator may display error number “Er.07” (In this case, the output signal percent and “Er.07” are displayed alternately every two seconds). Although “Er.07” is displayed, there is no need to worry and you may proceed to the next step. However, should any other error number be displayed, take the appropriate measure in reference to Section 2.4 Self-Diagnostics, “Errors Messages.”

(Note 1)

IMPORTANT

1. Do not turn off the power to the transmitter immediately after completion of the change in the LRV (and/or URV) setting(s). Note that powering off within thirty seconds after setting will ca use a return to the previous settings.

2. Changing LRV automatically changes URV to the following value.

URV  previous URV  (new LRV  previous LRV)

3. If the range-setting push-button and external zero-adjustment screw are not touched during a range-change operation, the transmitter automatically switches back to the normal operation mode.

(13) Sensor Trim

Each DPharp EJA Series Transmitter is factory characterized. Factory characterization is the process of comparing a known pressure input with the output of each transmitter sensor module over the entire pressure and temperature operating range. During the characterization process, this comparison information is stored in the transmitter EEPROM. In operation, the transmitter uses this factory-stored curve to produce a process variable output (PV), in engineering units, dependent on the pressure input. The sensor trim calibration procedure allows you to make corrections to the calculated process variable.

There are two ways to trim the sensor: full sensor trim and zero trim. A full sensor trim is a two point process, in which two accurate end-point pressures are applied (equal to or greater than the range values), and all output is linearized between them. A zero trim is a one-point adjustment typically used to compensate for mounting position effects or zero shifts caused by static pressure. (See section 1.1.1)

(15) Burst Mode

The transmitter continuously sends the data stored in it when the burst mode is set on. Either one of measured pressure variable, % output value, or 4 to 20 mA output value can be selected and sent. The data is sent intermittently as a digital signal at 75 ms intervals when the transmitter is set in the burst mode. Therefore, communication by the HART simultaneous communicator is also possible.

(16) Multidrop Mode

“Multidropping” transmitters refers to the connection of several transmitters to a single communications transmission line. Up to 15 transmitters can be connected when set in the multidrop mode. To activate multidrop communication, the transmitter address must be changed to a number from 1 to 15. This change deactivates the 4 to 20 mA analog output, sending it to 4 mA. The alarm current also is disabled.
