Set The Range Function
To set the 3 programmable ranges:
• Enter the range function mode by pressing the Range button on the front panel.
L—100 M—1000
H—10000 Mode—AUTO
• Use the ◄► arrow keys to blink the range to be set: low (L), medium (M), or high
(H).
• Use the ▲▼ arrow keys to enter the upper value of the range (all ranges begin at 0
ppm). Repeat for each range you want to set.
• Press Enter to accept the values and return to analyze mode.
Note: The ranges must be increasing from low to high, for example, if range 1 is set as
0–100 ppm and range 2 is set as 0–1,000 ppm, range 3 cannot be set as 0– 500
ppm since it is lower than range 2.
Fixed Range or Autoranging Analysis
To switch from autoranging to fixed range analysis:
• Enter the range function by pressing the Range button.
• Use the ◄► arrow keys to move the blinking over AUTO.
