General
The tolerances, linearity errors and temperature factors of the components used in the Beamex
Calibrators have been carefully considered during the specification tests at the factory. All nec-
essary parameters have been saved into the EEPROM memory of each measurement module.
It is not necessary to renew the calibration if certain components in the analogy part of the cali-
brator are not replaced. Anyhow, some characteristics can deviate from the original values dur-
ing the time. The periodical calibration is thus necessary in order to maintain the full accuracy of
the calibrator. In the beginning of the calibrator’s life span, the recommended calibration period
is one year. When the calibration history has been established, the calibration period can be
extended.
The whole calibration procedure can be made without opening the calibrator. The calibration
procedure is made as easy as possible. The calibration requires, however, some very accurate
instruments. If You do not have all the necessary calibration instruments, send the device to
Beamex’s accredited calibration laboratory for calibration.
Equipment Required for Performing the Calibration
For the complete calibration you need the following equipment:
1) DC calibrator, capable of generating the
- currents, voltages and low voltages measured with the E module.
- low voltages measured with the ET module.
2) DC meter(s), capable of measuring the
- currents generated with the E module
- currents, voltages and low voltages generated with the ET module
- generated voltages in the calibration of the ET module's resistance simulation.
3) Frequency generator capable of generating the frequencies measured with the E module.
4) Frequency measurement meter, capable of measuring the frequencies generated with the
ET module.
5) Precision resistors, for calibrating the ET modules resistance measurement.
6) A good quality thermocouple of type E, J, K or T. The sensor wires should be continuous
without extension or plug. The error of the sensor output at the condition where the sensor is
in the used temperature reference and the reference junction in 20 to 30°C should be known
and taken into account in the calibration.
7) An ice bath or another known temperature reference. The combined uncertainty of the tem-
perature reference and the thermocouple together should be less than 0.05°C.
8) A dead weight tester with the accuracy of 0,02 % RDG or better for the generation of the
necessary testing pressures. Required for the different pressure modules used with the cali-
brator.
You can replace items 6 and 7 with a small size temperature sensor and measuring device with
calibrated accuracy better than 0.05°C. The sensor must be small enough to fit inside the RJ
module. It should not noticeably conduct heat to or from the environment.
The accuracy of the necessary equipment should be about three times better than the accuracy
specified for the calibrator (see the calibrator’s Technical Data Sheet). If the accuracy of the
calibration equipment are worse, the calibration period should be shorter.

Calibrating and Adjusting the Calibrator
Calibration
Since adjusting the measurement ranges affect the generation ranges (via feedback measure-
ment), all Quantity and Function/Port settings should first be calibrated before making any
adjustments. Do the calibration in Basic Mode and use the recommended calibration points pre-
sented on page 4or any other suitable set of calibration points.
When all calibrations are done, prepare for enabling the adjustment mode by shutting down the
calibrator. To save the calibration date, you need to enable the adjustment mode even if no ad-
justment is required. For further information, see next chapter.
Enabling the Adjustment Mode
By default, the calibrator does not support adjustment of its
own measurement generation and simulation signals. This
prevents the calibrator from being accidentally adjusted.
To enable the Adjustment Mode, do as follows:
1. Start the calibrator. When the screen with the mod-
ule version numbers etc. appear, press the D/Wait
function key
Note.
Pressing the D/Wait function key is not needed if the calibrator's
calibration due date has expired. Then the calibrator beeps and
stops automatically on this screen and displays the message
"Calibrate soon".

2. Press the key.
Check that the text "Adjustment Mode enabled" appears on the status bar.
Enabling the Adjustment Mode makes the Adjustment menus available.
To start adjusting the calibrator, select:
D/Menu, C/Others, 2/Maintenance, 2/Calibrator Adjustment and
1/Start Adjustments.
Notes:
The commands apply when the calibrator is in Basic State.
The measurement window of a Quantity is enlarged to indicate that calibration/adjustment is in progress.
If there is need for adjustment see chapters Adjustment of Measurement Ranges and
Adjustment of Generation/Simulation Ranges on pages 6and 11 respectively.
If no adjustment is needed, set the calibration date into the calibrator’s memory. To do that, see
chapter Setting the Calibration Date When No Adjustment Was Required on page 16.

Adjustment Points for a Barometric Module
The barometric module's zero correction point range is 800 … 1200 mbar (11.6 … 17.4 psi). The
span correction point range is the same but there should be at least 200 mbar abs (approx.
2.9 psi abs) difference between the used zero adjustment and the used span adjustment point.
The connector for the Barometric Module is on the back side of the calibrator. The thread is M5.
Note.
Usually a one point trim is enough for adjusting the barometric module. This is done by comparing the atmospheric
pressure readout of the calibrator’s barometric module to the readout of a more accurate barometric pressure indicator.
When the correct barometric pressure is entered, the calibrator actually adjusts the zero point so that the readout for
the current atmospheric pressure is the same as the entered value.

Adjusting the Temperature Measurement of the
Internal Reference Junction Module
For obtaining best results when adjusting the Internal
Reference Junction Module, do the adjustment after the
calibrator has been shut down and not connected to a
charger overnight. Then the temperature inside the cali-
brator is stabilized to the same temperature as the envi-
ronment.

Adjustment of Generation/Simulation Ranges
The accuracy of a generation range depends on the accuracy of the respective measurement
range. Therefore the measurement range should be adjusted before trimming the generation
range. Trimming the generation range affects the overshoot and damping of the generated
value.
Several of the calibrators generation range adjustment windows include the feedback measure-
ment value. This can be used for trimming the generation range. Using an external Digital Mul-
timeter is optional for these measurement ranges.
Adjusting the Current Generation in E Module (0 … 25 mA)
Quantity: Current
Function/Port: E: Current Source/Sink
Power supply needed for the current generation can be
provided either from the calibrator or from an external
power supply unit. The connection depends on the used
power supply.
The lowermost measurement value in the current gen-
eration window is the calibrator’s own feedback meas-
urement of the generated current. It is accurate enough
for trimming the generated value. The Digital Multimeter
connected to the loop is optional.
Power Supplied from the Calibrator
The uppermost picture defines the connection when the
calibrator provides the power supply.
External Power Supply
The lowermost picture defines the connection when an
external device is used for power supply.
Adjustment Procedure
The adjustment procedure is the same for both connec-
tions.
Adjustment point ranges, mA
Low: 0.5 …5
High: 20 …25
Move the field indicator to the uppermost field and enter
a current generation value that is inside the limits of the
low adjustment point range. Enter the correct current
seen on the Digital Multimeter’s display to Span Refer-
ence Value field in the calibrator. Then generate a cur-
rent that is inside the high adjustment point range and
enter the correct value for that point too. Repeat the low
and high adjustments until the current generation is ac-
curate enough.

tion/Port combination or save the adjustment result as

For feedback measurement adjustment point ranges 1 and 2, only the lowermost value in the voltage generation win-
dow (the feedback measurement value) is changed.
The feedback measurement adjustment point range 3 is both for the voltage generation range and the feedback meas-
urement adjustment. Thus both values are updated.

Saving Adjustment Data
The adjustment data has to be saved. Otherwise they
are only valid until the calibrator is shut off.
Open the Save Adjustments window with the following
commands:
D/Menu, C/Others, 2/Maintenance,
2/Calibrator Adjustment and
3/Store Adjustment Data.
Enter the Calibration Laboratory name and edit the cali-
bration period if needed. Move the cursor to a module
name (see picture) and save the data by pressing the
C/Save Data function key.
Note.
The adjustment data can only be saved if it is acceptable (stays within the
limits that the calibrator approves).
Saving adjustment data need not be done individually for each Adjustable
Quantity and Function/Port Combination. When adjustments are saved,
all changed adjustments values are automatically saved.

Setting the Calibration Date When No Adjustment Was Required
If none of the Quantities in a module did need any ad-
justment, here's the procedure for saving the calibration
date and the calibration laboratory name:
Make sure that you start the calibrator with adjustment
mode enabled. For instructions on how to do this, see
chapter Enabling the Adjustment Mode on page 5.
Start the Adjustment Mode by pressing
D/Menu, C/Others, 2/Maintenance,
2/Calibrator Adjustment and 1/Start Adjustment.
Note.
Although no adjustment is needed, the calibration date can only be
entered when Adjustment Mode is started.

Update the calibration date and the calibration laboratory name for all modules that were cali-
brated but did not need any adjustment.
Hint.
The Date cannot be edited. It is taken from the calibrator’s internal clock.
To change the system date before setting the calibration press A/Close, A/çBack and then 1/Time/Date (starting
from the Module Settings Window). Then update the calibration date in the Module Settings Window and return to set
the time and date back to “real time”.
Ending Adjustment Mode
To return to normal use of the calibrator press:
D/Menu, C/Others, 3/Calibrator Adjustment and 1/End Adjustments.
Then the calibrator prompts you to shut off the calibrator.
