Chapter 2 - MEASUREMENT MODE
HI9828 HI9828 HI9828 HI9828 HI9828 can read at the same time different parameters from the same probe.
As described in the previous section, up to 3 sensors can be mounted on the
probe.
• Connect the probe to the meter and carefully fix the protection sleeve.
• Immerse the probe into the sample while paying attention to avoid stones.
• Press the on/off key to turn the meter on: the display shows “HANNA HI9828”
and the firmware version, then enters the measurement mode.
• The display shows the readings of all enabled parameters and the location
coordinates (depending on model and if the GPS feature is enabled). See Chap-
ter 3 for details.
• Press <Log> to store the readings or <Menu> to enter in the main menu. See
Chapter 5 for details.
Note Note Note Note Note If no probe is detected, the message “Probe disconnected!” appears. In
this case only the <Menu> softkey is available and only a few func-
tions are active (i.e. those that not require readings).
Up to 12 measurements can be enabled at the same time, and based
on number of enabled parameters, the display automatically changes
its resolution and sizes the digits to fit the screen.
A small “A” letter added to the µS/cm or mS/cm unit, refers to an actual
conductivity value, i.e. a conductivity reading with no temperature com-
pensation.
When a measurement is out of range or not available, the nearest full
scale value will slowly and continuously blink.
If GPS is enabled and no GPS signal is received, the last detected GPS
coordinates will blink on the LCD.
Press the lamp key, to turn the backlight on and off. After one minute
with no key pressed, the backlight automatically turns off.
