15Q. Manage Calibra on Factors >
: Crea ng calibra on factors and use of Non-ILT calibra on
factors can cause errors in light level readings. The calibra on factors listed in the Op cal
Calibra on Cer ficate from ILT are N.I.S.T. traceable and are performed in our ISO17025 accredited
lab by trained and experienced technicians. Use of altered calibra on factors can void traceability.
15Q.1. Factor Number:
Numbers range from 1-20. The ILT2500 stores up to 20 calibra on factors
which are selected using Factor number as shown in sec on in 15B.
15Q.2. Factor Descrip on:
Enter a nick name, component model&Serial number, or sensor stack
ie lux sensor, 033#234, 005/UVA/W
.
(Note: spaces are converted to a “-”)
15Q.3. Factor:
Units Enter the units for the readout ie. lux (Note: Spaces are converted to a “-”)
15Q.4. Sensi vity Factor:
Enter sensi vity factor from the ILT calibra on cer ficate. 2.09e-09
(see red arrow on cal cert on page 14)
15Q.5. Resul ng Light Level:
Allows the user to enter a know value for the light level under test
and create a calibra on factor to force the meter to read the correct value.
ie. LED with 40 lumens is measured. Enter 40, press set. A new calibra on factor will be created to
read 40 and auto-range up and down through other light intensi es.
15Q.6. Factor Adjustment:
User can enter a value to alter the calibra on factor by for example if
adding a neutral density filter with a3enua on of 10, enter 10 and press set. A new calibra on
factor, that has changed by 10, will be entered in the next available channel.
