LTL2000S(Q) Display

Explanation (The following messages are possible)

 

 

 

 

 

 

R: 146 Q: 64

The latest measurement results.

 

 

 

 

 

 

Rl Signal: 143

The measured Rl “raw signal” level.

 

 

Rl Out of Limit*

The Rl value is negative.

 

 

Rl Sig Overflow*

Warning: unreliable measurement!

 

 

 

If the measured signal is greater than a predefined

 

 

 

limit then a warning will be displayed for one second

 

 

 

before the Rl Sig value is shown.

 

 

 

Error sources: Rl marking exceeds the dynamic range

 

 

 

of the instrument, failure in the optical system e.g.

 

 

 

dew or dirt on the front window or it can be an elec-

 

 

 

trical failure.

 

 

Rl Stray L: 0

The measured stray light representing the amount of

 

 

 

light getting into the instrument from outside. Stray

 

 

 

light levels under acceptable predefined limits is dis-

 

 

 

played as 0.

 

 

Rl High Stray L*

Warning. A high stray light signal can indicate prob-

 

 

 

lems with direct sunlight from a low sun on a very

 

 

 

rough or uneven surface. Special precautions must, if

 

 

 

necessary, be taken to hinder the light from shining

 

 

 

directly on the measurement area. A warning will be

 

 

 

displayed for one second, if the signal gets critical,

 

 

 

before the Rl Stray L value.

 

 

VBat Rl: 11.2V

The battery Rl voltage measured while the lamp is on.

 

 

 

The reading can be used to check the charge condition

 

 

 

of the built-in 12 V battery.

 

 

Low VBat Warning*

A warning will be displayed for one second before the

 

 

 

VBat Rl voltage is shown, if the voltage under load

 

 

 

drops to a critical low value. If the battery voltage

 

 

 

gets very low, the instrument will shut off during the

 

 

 

measurement because the battery voltage drops fur-

 

 

 

ther when the lamp is lit. This condition will be re-

 

 

 

ported in the display on the next power on. Measuring

 

 

 

will not be possible until the battery is recharged.

 

 

 

 

 

 

Qd Signal: 875

The measured Qd signal level.
