UIT2400 INSTRUMENTATION MANUAL REV A, May 2020

15Q. Manage Calibration Factors:
Creating calibration factors and use of Non-ILT calibration factors can cause errors in
light level readings. The calibration factors listed in the Optical Calibration Certificate
are N.I.S.T. traceable and are performed in our ISO17025 accredited lab by trained and
experienced technicians. Use of altered calibration factors can void traceability.
15Q.1. Factor Number:
Numbers range from 1-20. The UIT2400 stores up to 20
calibration factors which are selected using Factor number as shown in section in 15B.
15Q.2. Factor Description:
Enter a nick name, component model & Serial number, or
sensor stack
ie Care222 sensor, 033#234, 005/UVA/W
.
(Note: spaces are converted to a “-”)
15Q.3. Factor:
Units Enter the units for the readout ie. W/cm2
15Q.4. Sensitivity Factor:
Enter sensitivity factor from the ILT calibration certificate.
2.09e-09 (see red arrow on cal cert on page 14)
15Q.5. Resulting Light Level:
Allows the user to enter a known value for the light level
under test and create a calibration factor to force the meter to read the correct value.
i.e. Care222 with 40 uW/cm2 is measured. Enter 40, press set. A new calibration factor will
be created to read 40 and auto-range up and down through other light intensities.
15Q.6. Factor Adjustment:
User can enter a value to alter the calibration factor by for
example if adding a neutral density filter with attenuation of 10, enter 10 and press set. A
new calibration
factor, that has changed by 10, will be entered in the next available
channel.
15R.Firmware Update:
Ushio will contact you when new firmware for your device is available and provide instructions
how to upgrade.
15T. Save Settings:
Permanently saves all settings to memory (until Save Settings is pressed
again) When applied a box will appear around the button to indicate completion.
15U. Restore Defaults:
Returns all datalight software settings back to the factory default
