Battery Replacement
A 9v alkaline battery powers the IQ150 meter. The expected battery life is
200 hours of operation. The
BATT
icon on the display indicates low battery
voltage. Replace the battery whenever low voltage is indicated.
To Replace the Battery:
1.
Disconnect all connectors from the meter.
2. Remove the meter from the protective holster and turn the
meter upside down.
3.
Gently open the battery compartment cover on the back of the
meter.
4.
Remove the old battery, and install the new battery.
5.
Replace the cover.
Automatic Shutoff
If the meter is on battery power and no key is pressed for 12 hours, the meter
will turn off automatically. Calibration is retained in memory after shutoff. If
the meter is operating on battery power and an error message is displayed for
20 minutes, the meter will turn off automatically. If the meter is operating on
AC power, it will not automatically turn off.
AC Power Adapter
The IQ150 pH meter can be used with an optional AC power adapter. Use
only IQ Scientific Instruments AC power adapters. The use of other adapters
may cause AC power interference that may result in unstable readings.
The meter automatically identifies the presence of the AC adapter and will not
use the internal 9-volt battery when the AC adapter is attached.
