Chapter 2 - MEASUREMENT MODE
HI 9828 has the possibility to read at the same time different parameters from
the same probe. As described in the previous sections it is possible to mount up
to 3 sensors on the probe.
2.1 PROCEDURE
• Connect the probe to the meter; remember to fix with care the protection
sleeve to the probe.
• Immerse the probe in the sample paying attention to avoid stones.
• Turn on the meter by pressing the On/Off key. The meter visualizes “Hanna HI
9828”, the software version and then it enters measurement mode.
• The meter visualizes the readings relative to all the enabled parameters. See
Chapter 3 for more information.
• Press LOG to store the readings or MENU to enter in the main meter menu.
See Chapter 5 for more information.
NOTES: If the meter does not find the probe the message “Probe disconnected!”
appears. In this case the only available softkey is Menu and it is possible
to operate only with the functions that do not require a reading.
It is possible to enable up to 12 parameters. Based on the number of
enabled parameters the graphical resolution change, the lower the
number of parameters, the bigger the digits size.
A small A letter added to μS/cm and mS/cm refers to Actual conductiv-
ity, i.e. the conductivity reading without temperature compensation.
When a measure is out of range, the maximum (or minimum) value for
the measurement will slowly and continuously blink.
By pressing the lamp key it is possible to turn on/turn off the backlight.
After one minute passed without pressing any key, the backlight turns
off automatically.
