Test temperature (required entry)
The permissible temperature range for measurements is +15 °C (56 °F) to 30 °C (86 °F). Enter the measured
temperature in °C or °F
Test volumes/Nominal Values
The right-hand section of the entry window contains the table for entering the values you have determined in
the gravimetric test. Volumes are suggested for the selected instruments in the “Test volume” line in the table
header:
Column 1: Nominal volume
Column 2: 50% of nominal volume (Digital/Variable type only)
Column 3: 10% resp. 20% of nominal volume (Digital/Variable type only).
The test volumes can be modified as required by overwriting them. You can also delete individual columns; for
example, if only two volumes are to be tested in a variable instrument.
The “Nominal Values” line displays the ideal measurement values, depending on the temperature.
Entry of measuring results
☞ The entry fields for measuring results have a
white background.
☞ Click into the first entry field “x 1” in the first
white column
☞ Manual entry of results:
Enter value “x 1” and confirm with ENTER. This
takes you automatically to the next entry field.
Enter the remaining results.
☞ Automatic transfer of results from the
balance (optional):
If the balance is connected, results are trans-
ferred automatically from the balance (Profes-
sional Version). To transfer the weighed value,
press either the “Print” button on the balance, or the F2 key on your PC keyboard. Press “ENTER” to confirm
the weighed value, which will move you automatically to the next entry field (see Section 5.5 “Connecting a
balance”).
☞ If other columns have a white background, these have to be filled in with results also.
Traffic light function:
☞ Once at least three measuring results have been entered (concerning multichannel instruments after each
channel), EASYCAL™ will calculate the average or error limits and compare them with the error limits selected
in the next screen shown below. The default error limits set are those defined by DIN EN ISO 8655.
☞ If the measuring results are outside the error limits, the traffic light in the Entry of Measuring Results - Liquid
Handling shows red, if they are within the error limits, it will show green.
☞ Therefore, prior to entering the measuring results, please set error limits in the screen “Entry of tolerance
limits” shown below. Subsequently, the measuring results can be entered. (For instruments contained in the
database the error limits defined in the operating manual and the ISO 8655 are already stored).
Instrument type Number required Maximum number
Single channel instrument 3 45
8-channel instrument 24 240
