Short Press
Momentarily press the button to
enter MENU mode. There are six menu
items by pressing the button
shortly to loop. The menu items are
described in the table x.
Short Press
In the MEASUREMENT mode the user
presses it to manually log one pH reading
onto the meter memory.
Note that the new data will automatically
overwrite the old data in memory
In the MENU mode :

Short Press
In the MEASUREMENT mode,
momentarily press the button to
freeze a displayed reading on the LCD and
enter FREEZE mode. The FREEZE display
icon will appear.
In the MENU mode, save and implement
the Menu item then returns to
MEASUREMENT mode.
Note:
When LCD backlight is off, press any button to turn on the backlight before
operation. LCD backlight will turn off automatically after 60 seconds of
button inactivity.
Changing the Operation Mode
BE500 pH meter has four operation modes: MEASUREMENT, MENU, DATA
and FREEZE mode (see table 2). Change the operation mode from four
available modes depending on the purpose of use. The status icon
indicates the current mode.

Users can change the operation mode using the corresponding key.
However changing to the MENU mode, DATA mode, or FREEZE mode is
possible only from the MEASUREMENT mode. When changing to a
different mode, first change to the MEASUREMENT mode and then
change to the desired mode.
Menu Mode Operations
By pressing the button, the meter enters into MENU mode. There
are six menu items by pressing the button shortly to loop. The
menu items are described in table 3.

Connecting Electrodes and Temperature Sensor
The pH electrode connects to the BNC jack on the top left of the meter.
Align the BNC connector slots with the posts of meter's jack and rotate
connector clockwise until it locks. Do not force it. To remove, rotate the
connector in counter-clockwise direction until it unlocks, and slide the
connector off the jack.
The temperature Sensor connects to the micro aviation jack on the top
middle of the meter.
When measurements have been completed, be sure to store the pH
electrode in its protective vial/cap.

Operating Hints
This section gives some brief operating hints and good laboratory
practices to help assure trouble free pH measurements.
1. If you are measuring hot or cold samples without the use of an ATC
probe, the values displayed are not accurate. You should be calibrating
and measuring at room temperature.
2. When transferring from one sample to another, always rinse the
electrode with distilled water and blot dry. Handle the electrode carefully
and do not use it as a stirring rod.
3. Use new calibration buffers.
4. For small sample volumes, make sure that the pH bulb is in contact with
the sample.
5. Response time is a function of both the electrode and the solution.
Some solutions have very fast response while others, particularly those
with low ionic strength, may take several minutes.
6. Samples must be in solution (water). Users cannot measure the pH of a
dry sample.
7. See the next sections for general pH electrode maintenance.
PH ELECTRODE
The pH electrode contains polycarbonate silicone rubber material and
glass components at the part contacting the sample. Before measuring the
sample, please confirm that your sample solution does not harm the
above materials.
There is a vial stored with KCL (potassium chloride) storage solution on top
of the electrode. The electrode use procedure are below:
1. Before using, loosen the cap of the vial, take out the electrode.
