Bluelab Combo Meter

1.0 Introduction to Bluelab Combo Meter

The battery operated Combo Meter measures nutrient, temperature and pH levels
by use of one or the other of the two probes connected to an electronic meter.
The meter has a liquid crystal display (LCD) digital readout.

1.1 Button Functions

The function panel has three press buttons;
1
pH/Calibrate, Nutrient/Cal7.0 and
Temp/Cal4/10. A short press of any button
turns the meter on. The meter turns off
automatically when no further buttons are
pressed for a period of 4 minutes. Another
short press starts it again.
The meter can be manually turned off by
holding the pH button down until the display
starts flashing. The pH button is pressed again
while the display is flashing.
The buttons have a short press and long press
function.
A short press means a button is released in
about one second. The long press is a button
being pressed for at least three seconds and
released when the display starts flashing.

1.2 Meter Calibration

The pH of the meter is calibrated after each probe clean to ensure reading accuracy.
1
Solutions used for calibration are carefully stored and replaced occasionally because
pH reading accuracy is dependant on the accurracy of the calibration solutions used.
If measuring a pH below 7.0 is normal, the meter is calibrated using pH7.0 and pH4.0
calibration solutions. If measuring a pH above 7.0 is normal, pH7.0 and pH10.0 solutions
are used for calibration.

1.3 Storage of Meter

1 The meter is kept out of direct sunlight to prevent irreparable damage to the LCD
screen; this includes storing in a cool, dry and clean place when not in use.
The meter unit is not waterproof but will withstand occasional water splashes. If the
meter does get splashed, it is wiped dry as soon as possible. Batteries are removed
if the unit is to be stored for a prolonged period.

1.4 ppm Scale

1 In relation to the ppm scale, 500 ppm = 1.0 EC = 10 CF.
