Remove the instrument from the packing material and examine it
carefully to make sure that no damage has occurred during shipping.
If there is any damage, notify your Dealer.
Each printing/logging pH meter is supplied complete with:
• HI1230B Combination pH Electrode
• HI7669/2W Temperature Probe
•AA size Alkaline Batteries (4 pcs)
• Paper rolls (5 pcs)
•Rugged Carrying Case.
Note: Save all packing material until you are sure that the
instrument functions correctly. All defective items must be
returned in their original packaging together with the sup-
plied accessories.
HI9224 and HI92240 respectively, are the first printing and printing/
logging microprocessor-based portable pH/°C meters in the world.
All pH measurements are automatically compensated for temperature
(ATC). The instruments' housing is made of rugged, lightweight mate-
rial, making it truly portable.
Three memorized buffers (4.01, 7.01 and 10.01pH) and automatic
buffer recognition technology make calibration simple. One or two point
calibration is possible, and the meter has a stability indicator. The
meters come equipped with a large, easy-to-read LCD.
Measurements can be performed with lab-grade precision in the field as
well as in the laboratory without compromising accuracy.
For long term field and lab applications, these meters can be connected
to a 12VDC adapter.
When in the logging mode HI92240 will store the present measurement
into memory at a user selected interval from 1 to 180 minutes. This
information can be retrieved at a later date for printing or can be
transferred to a computer through an infrared transmitter. The internal
software allocates memory space to store up to 8000 measurements.
An optional HI9200 transmitter can be connected to a computer's
RS232 port.
The HI92240 will transfer the data in seconds through the infrared
lights with no need for a cable between the transmitter and the meter.

INITIAL PREPARATION
Each meter is supplied complete with batteries. Remove the back
cover, unwrap the batteries and install them while paying attention
to the polarity.
To prepare the instrument for use, connect the pH electrode to the
BNC connector located on the top of the instrument. Then connect the
temperature probe to the appropriate connector. The temperature
probe can be used independently to take temperature measurements,
or it can be used in conjunction with the
pH electrode to utilize the meter's ATC
capability. If the temperature probe is left
disconnected, a default temperature of 25°C
is assumed and the "C" symbol blinks.
To switch the HI9224 on, press the ON/OFF
key.
To switch the HI92240 on, press the RANGE
key.
To maximize battery life, the display is auto-
matically switched off after 5 minutes of non-use.
However, the meter will continue to monitor (if
in the logging or recording mode) pH and
temperature. To revive the display, press the
RANGE key. Before proceeding with pH mea-
surements follow the calibration procedure.
