Pressure calibrator
Overview
The intrinsically safe, advanced modular calibrator (AMC) is
part of a set of hand-held modules that can be quickly put
together to include a wide range of calibrator functions.
Advanced modular calibrator, DPI 620-IS (this user
manual): This is a battery-powered instrument for electrical
measure and source operations and HART® communications;
see Table A1 (front cover). It also supplies the power and user
interface functions for all the add-on modules. Use the
touch-screen to display up to six different parameters.
Pressure module carrier, MC 620-IS (this user manual):
This attaches to the DPI 620-IS calibrator to make a fully
integrated pressure indicator instrument. To measure and
display pneumatic or hydraulic pressures, up to two
interchangeable pressure modules can be used at a time.
When not in use fit blanking device (part number 191-369).
Pressure modules, PM 620-IS (this user manual):
Optional item. These modules attach to the pressure module
carrier (MC 620-IS) or to a pressure station (PV 62x-IS) to give
the DPI 620-IS calibrator the necessary pressure measurement
functionality. They are fully interchangeable “plug and play”
modules with no initial set-up or user calibration.
Optional item. To make a fully integrated pressure calibrator,
attach the DPI 620-IS calibrator to one of the three pressure
stations:
• two pneumatic pressure stations gives an accurate and
controlled pressure and vacuum conditions:
PV 621-IS: -950 mbar to 20 bar (-13.5 to 300 psi) version
PV 622-IS: -950 mbar to 100 bar (-13.5 to 1500 psi) version
• one hydraulic pressure station gives an accurate and
controlled hydraulic pressure conditions:
PV 623-IS: 0 to 1000 bar (15000 psi)
The advanced modular calibrator (AMC-IS) and the pressure
module (PM 620-IS) are part of a set of hand-held modules that
can be quickly put together to include a wide range of calibrator
functions.
To give the attached equipment overpressure protection, there
are pressure relief valves (PRV) available for all the pressure
stations.

7.1 Introduction
7.2 Analysis
This section gives examples of the documenting functions
available with the DPI 620-IS calibrator. There are two options:
Analysis (Section 7.2): This function compares the data from
two Channels on the DPI 620-IS calibrator: the device under
test (DUT) and a reference instrument.
It calculates the % span or % reading error for the device and
then gives a pass or fail indication.
Run Procedure (Section 7.3): This uses the Intecal
Calibration software (Optional item) to download a calibration
procedure.
Before starting:
• Read and understand the “Safety” section.
• Do not use a damaged instrument.
Note: Use only original parts supplied by the manufacturer.
To use the Analysis function, set the functions in the two
channels for comparison (Section 2.8.4). Then use these

• change the device configuration (range, units, damping).
One HART device (a master device) starts and controls the
communications with commands. The field device (a slave device)
uses each command to make a change and/or send data back.
Two master devices are permitted: a primary master (usually the
main control and monitor system), and a secondary master

Methods
Only a single tap on the screen is required to open any item in
black or open any folder.
TerminologyPV = Digital Value of Primary Variable (i.e. this is the parameter that
the transmitter measures - pressure, current, voltage).
PV AO = Digital Value of Primary Variable mA current.
DPI 620-IS CH1 = Analogue Value of Primary Variable (actual
calibrated value).
DPI 620-IS CH2 = Analogue value of Primary Variable mA current
(actual calibrated value).
DPI620 P1, P2 and IDOS reflect the analogue pressure values
measured by the relevant pressure ports on the DPI620-IS.
Range ValuesPV LRV = Lower range value of Primary Variable.
PV URV = Upper range value of Primary Variable.
Example: Transmitter under test has a range of -200°C to +800°C.
Setting the LRV to -20°C (zero value) and URV to +20°C (span value)
allows re-ranging the transmitter (zero & span) to specified limits.
The PV % of range in this example for a PV = 0°C is equal to 50%.

correctly navigate through the menus to the
loop test button:
• Press the loop test button.
• Press OK and the loop test executes.
• The loop test can be put into various modes,
typically 4 mA and 20 mA should be selected.
The Analogue value of Primary Variable mA
current (actual calibrated value) of the
transmitter can be seen by selecting the CH2
drop-down box. If this value needs adjusting
then use the analogue trim (sometimes referred
to as D/A trim) in the calibration menu.
Analog trim (D/A trim)
• Using the DPI 620-IS, an analogue trim can be performed on
the 4 to 20 mA loop without having to connect any external
reference meters.
• Navigate to the calibration folder and select the D/A trim
method. Follow the on-screen instructions.

current (actual calibrated value) into the box
using the key-pad and then press Set. Repeat
this process with 20 mA selected. This will
accurately calibrate the transmitter’s output 4
to 20 mA loop current.
• Using the DPI 620-IS, a sensor trim on most Primary Variables
can be performed without having to connect any external
reference meters. If the Primary Variable is a pressure device
use the DPI 620-IS and PV 62x-IS pressure generation stations
to provide the pressure source. Alternatively, use DPI 620-IS
and MC 620-IS to accurately measure pressure.
• Navigate to the calibration folder and select the sensor trim
method. Follow the on-screen instructions.
• In this example a lower trim has been selected.
The DPI 620-IS is set-up to source a Primary
Variable to the transmitter. CH1 has been
configured to output 0°C. This can be done by
selecting the Switch App button at the bottom
of the method window and configuring the DPI
620-IS to simulate an RTD at 0°C. The Analogue
Value of the Primary Variable can be seen by
selecting CH1 on the drop-down menu.
• Type the Analogue Value of the Primary Variable
(actual calibrated value) into the box using the
key-pad and then press Set. Repeat this
process with an upper trim value. This will
accurately calibrate the transmitter’s sensor
output.

8.4 Failed to find a
device
The following is a checklist of what to do.
• When using the DPI620-IS to supply power, make sure that the
®
internal HART
resistor is turned on.
• Check the preferences option and set this to find first , then
re-start the application. This will ensure that SDC625 finds a
device that is not at poll address 0.
• When supplying power to the transmitter, check that the loop
current measured on channel 2 is between 4 and 20 mA. In
alarm conditions it is possible for it to be parked at 21.5 mA or
3.9 mA. However, if the current measured by channel 2 is far
from these values, there must be a configuration fault.
• If the transmitter is powered externally with an external HART
resistor, ensure that channel 2 has been turned off.

(CH1): CJ (measure)
Note: Do the TC mV (measure) calibration (Section 10.12)
before the cold junction calibration.
1. Connect the applicable calibration equipment in Table 10-1;
for example: see Section 3.2.10 (Example procedure:
Measure or simulate a thermocouple (or TC mV)),
example A.
2. Set-up the DPI 620-IS calibrator:
Function = TC (measure);
TC Type = K Type
CJ Compensation; Mode = Automatic
3. Set the reference unit temperature: 0°C
4. Let the equipment get to a stable temperature
(minimum: 2 hours since the last power on).
5. Record these values:
• the thermocouple temperature given on the reference unit,
T (actual).
• the thermocouple temperature given on the calibrator,
T (measured).
• the CJ temperature given on the calibrator, CJ (measured);
for example: in Section 3.2.10 example (A),
CJ (measured) = 32.66.
6. Calculate the CJ (Cal Value) as follows:
CJ (Cal Value) = CJ (measured) - T (actual) + T (measured)
7. Use the calibration menu (Section 10.3) to do a one-point
calibration for the CJ (measure) function.
When the screen shows “Sampling complete. ... ”, set the
correct Cal Value = CJ (Cal Value) in step 6.
8. To make sure the calibration is correct, select the TC
(measure) function; see Section 3.2.10, (A).
9. Make sure the DPI 620-IS calibrator gives a thermocouple
temperature that agrees with the temperature on
the reference unit ±0.1°C (0.2°F).

620-IS)
1. Assemble the pressure indicator with the necessary
PM 620-IS modules and connect the instrument to the
pressure standard; see Section 4.4.4 (Example procedure:
Measure pressure).
2. Let the equipment get to a stable temperature (minimum:
60 minutes since the last power on).
3. Use the calibration menu (Section 10.3) to do a two-point
calibration (Zero and +FS) or a three-point calibration (-FS,
Zero and +FS). Refer to Table 10-13.

4. To make sure the calibration is correct, select the applicable
pressure function; see Section 4.4.4, and apply these
pressure values:
• Ranges g: 0, 20, 40, 60, 80, 100 (%FS)
Then: Go back to 0 in the same steps.
Then (three-point calibration only):
-20, -40, -60, -80, -100 (%FS)
Then: Go back to 0 in the same steps.
• Ranges a: 0, 20, 40, 60, 80, 100 (%FS)
Then: Go back to 0 in the same steps.

5. Make sure the error is in the specified limits; see the tables
for Gauge Ranges or Absolute Ranges given in the
datasheet (supplied on the CD: P/N UD-0002); use the
values in column “Total uncertainty ... “.
The specified values include an allowance for temperature
changes, reading stability for one year, and the uncertainty of
the standard used for calibration.
