8.1.2 Beeper/Error Icon
When a key is pressed that calls for the instrument to perform a
function that is not available at that time, the beeper is activated
once and the error icon appears on the display. Each time the
unacceptable command is entered, one beep sounds.
If an unavailable program number is entered, the beeper also
sounds. Program numbers must range from 101 to 110 (user
programs) and 1 to 100 (Hach programs). Entering a number
other than these results in the beeper sound and the error icon
briefly illuminates. After this beep sounds, re-enter the
proper number.
8.1.3 Concentration Out of Range
An out-of-range condition is indicated by the illuminated LIMIT
icon. It means the sample concentration exceeds the range of the
programmed calibration. Make sure the test procedure is followed
correctly, dilute the sample (for over range samples) and rerun the
test. Each Hach test has an upper concentration value that defines
the program range. Measurements beyond that range
are unreliable.
8.1.4 Low Battery
The instrument continuously monitors battery voltage. If the
battery voltage falls to a level which indicates less than ten
percent battery life remains, the instrument automatically warns
the operator by displaying the
LOW BATTERY icon. Replace the
batteries as soon as possible for most reliable
instrument performance.
