Hanna Instruments HI 9026V - Manual (Page 5)

8 9
The instrument allows the user to program several parameters though a Setup
Menu.
To enter the Menu mode, while in normal measurement mode, press and hold
the SETUP key for about 5 seconds.
Once entered the Menu, each parameter can be changed by using the arrow
keys; then pressing the CFM key will confirm the value and scroll to the next
parameter.
The sequence of programmable parameters is as follows:
1. Acoustic signal: On (default) or Off
2. Auto-off feature: 20 minutes (default) or disabled
3. Temperature measure unit: °C (default) or °F
4. Calibration segments: On (default) or Off
5. Calibration time-out: 1 (default) to 14 days or disabled (0 days)
After setting the last parameter, pressing the CFM key will confirm the value
and return to normal measurement mode.
Notes:
• When reading is out of range, the display will flash the closest full-scale
value.
• If using pH electrode while in mV mode, the meter will measure the mV
generated by the pH electrode.
MEM and MR FUNCTIONS
From normal measurement mode, pressing the MEM key will freeze readings on
display and store into internal memory the current values (pH and tempera-
ture, or mV and temperature) together with “condition” and buffer segments.
The MEM tag blinks and the display remains frozen until the MEM key is
pressed again.
Note: While in MEM mode, the user can switch between pH and mV by
pressing the RANGE key.
Stored value can be recalled by pressing MR: the display will show the value,
together with the RCL & MEM tags, as long as the MR key is pressed.
Note: Pressing MR, only the range that was active at the time MEM was
pressed is shown.
BACKLIGHT FEATURE
The meter is provided with a Backlight feature, which
can be easily toggled on and off through the key-
board by pressing the LIGHT key.
Note: The backlight automatically shuts off after approximately 1 minute with
no buttons pressed.
