HI9017, HI9218, HI9219 and HI9318 are microprocessor-based bench­top meters designed to meet the most stringent demands of the laboratory.

They feature:

•user friendly rubber keyboard

•automatic calibration with memorized buffers values

•automatic or manual temperature compensation

•storage of calibration data even after the meters are shut off

•error codes to guide the user in calibration and troubleshooting
All these models incorporate a standard RS232C output for communi­cation with a computer.
The HI76405 electrode holder provided will hold your pH electrode
and temperature probe directly over the sample vessel which can be
placed on the enamel coated base of the holder. A magnetic stirrer
can also be placed on the enamel coated base if sample agitation is
required. The enamel coating is impervious to most chemicals and the
heavy steel base will not tip over easily.
These meters are perfect for use in Q.C. labs, R&D labs, environmen­tal testing, industrial processing, chemical treatment, waste water
treatment, drinking water analysis, titration, hydroponics, general ag­riculture, food processing and anywhere accurate pH measurements
are required.

• HI9017 pH/mV/°C meter automatically recognizes three stan-

dard calibration buffer values (pH 4.01, 7.01, 10.01). The pH
and temperature values are shown separately on the LCDs. A wide
mV range and high resolution allow for ORP or ion-selective
measurements (the range automatically switches from ISE to ORP
when readings exceed ±399.9 mV).

HI9017 comes supplied with HI1131B glass-body combination
pH electrode (with 1m/3.3' cable), HI7669/2W temperature probe

PRELIMINARY EXAMINATION

Remove the instrument from the packing material and examine it to
make sure that no damage has occurred during shipping. If there is
any damage, notify your Dealer.

Note: Save all packing material until you are sure that the instrument

functions correctly. All defective items must be returned in the
original packing with the supplied accessories.

(with 1m/3.3' cable), 12VDC adapter (HI710005 or HI710006),
pH 4.01 & pH 7.01 buffer solutions (20 mL each), HI7071
electrolyte solution (30 mL), HI76405 electrode holder and a
dust cover.

• HI9218 and HI9219 are programmable pH/°C meter with built-

in printer. They print pH values together with temperature, time
and date. These meter provide you with pH and temperature
readings simultaneously and separately on the LCDs and feature a
unique stability indicator. When the pH electrode stabilizes in the
sample, the "NO" on the LCD changes to "YES". This indicates that
the reading is correct and can be recorded. They automatically
recognize three standard buffers (4.01, 7.01 and 10.01 pH) for
calibration purposes. These meters are extremely user-friendly,
giving step-by-step instructions on the printer at every stage to
help the user.

HI9218 has been specifically designed for the food industry.
HI9218 comes supplied with FC100B plastic-body combination
pH electrode (with 1m/3.3' cable) while HI9219 comes with
HI1131B glass-body combination pH electrode (with 1m/3.3'

cable). HI9218 and HI9219 are also supplied with: HI7669/2W
temperature probe (with 1m/3.3' cable), 12VDC adapter (HI710005
or HI710006), pH 4.01 & pH 7.01 buffer solutions (20 mL each),
HI7071 electrolyte solution (30 mL), 5 replacement rolls of printer
paper, HI76405 electrode holder and a dust cover.

• HI9318 is a pH/mV/°C meter designed for logging data in various

applications. This programmable printing meter prints pH or mV
values as well as sample number, temperature, time and date.
The pH/mV and temperature values are displayed on separate
LCDs for ease of reading. It recognizes and memorizes three
different standard buffers (pH 4.01, 7.01 and 10.01) for calibra­tion purposes. The printer can be programmed to print in one of 6
different languages (English, French, German, Italian, Spanish or
Swedish). Once your language is selected you can simply prompt
the meter to calibrate and it will print step-by-step instructions
through the entire process making this meter perfect for use by
even non-technical staff members.

HI9318 comes supplied with HI1131B glass-body combination
pH electrode (with 1m/3.3' cable), HI7669/2W temperature probe
(with 1m/3.3' cable), 12VDC adapter (HI710005 or HI710006),
pH 4.01 & pH 7.01 buffer solutions (20 mL each), HI7071

(with internal reference) plug the electrode's BNC to the socket pro­vided (#1).

For electrode with separate reference (see page 58), connect the
measuring electrode's BNC to the BNC socket (#1) and the reference
electrode's jack to the socket provided (#2 or #3).

For temperature measurements and automatic temperature compen­sation connect the temperature probe to the °C socket (#4).

RESET button

The RESET button (#5) is used when the instrument displays errone­ous messages due to strong electrical interference or when the
instrument's power supply was disconnected before the meter was

Power connection

Plug the 12VDC adapter (HI710005 or HI710006) into the DC socket
(#7).

Plug the adapter into the mains.
Note: The instrument uses the following configuration.

It is recommendable to use the Hanna HI7710005 or HI710006
voltage adapters (supplied witht the meters) that use the proper
polarity configuration.

The meters can also be used with other adapters. In this case, remem­ber to check the correct polarity of your adapter before connecting it to
the meter.

Note: Make sure the main line is protected by a fuse.
Note: HI9017, HI9218, HI9219, HI9318 use a rechargeable battery

to retain the pH calibration data only. It lasts approximately one
month when fully charged. The battery is automatically charged
any time the meter is plugged-in (either turned on or off).

Notes:

1) If you need to unplug the instrument, press the OFF key before

disconnecting the meter from the mains. Only in this case will
the instrument retain the memorized data. Otherwise, the in­strument needs to be re-calibrated. In the case of a power
failure while the instrument is operational , re-calibration is
required.

2) When the instrument is initially switched on, the microprocessor

checks if any calibration data is in memory (i.e. if the offset is
within ±1 pH and the slope between 70 - 105%). If the
calibration data are not memorized, the offset and slope of the
instrument will be set to 0 mV and 100% respectively.

TAKING PH MEASUREMENTS

Make sure that the instrument has been calibrated for pH before
taking pH measurements (see page 18).

Connect the pH electrode (combination-type) or the electrode half cells
to the appropriate connectors on the rear panel (see page 11).
If automatic temperature compensation is required, connect the
HI7669/2W temperature probe to the proper socket on the rear panel
(see page 11).

Press the ON key to turn the meter on. The meter will
automatically default to the pH measurement mode.

Immerse the electrode and the temperature probe
in the sample and shake briefly. Wait for 30
seconds before taking readings.

IN HI 9218 AND HI9219

Press READY: "YES" confirms the read­ing is stable.

The LCD on the right shows the pH reading compensated for tempera­ture. The temperature reading is displayed on the LCD on the left.

Note: the electrode should be submerged approxi-

mately 4cm (1½") into the solution.
If the temperature probe is used, it should be
located as close to the pH electrode as possible.
If measurements are taken in different samples successively, it is
recommended that the electrode is rinsed thoroughly for better condi­tioning and to eliminate cross-contamination of the sample.

For the rinsing process, it is recommended to use a liberal amount of
the next solution to be measured.

Using refillable electrodes

Unscrew the small refill cap to open the refill hole during measure­ments. After measurements replace the refill hole cap.
This will increase the pressure and give a faster response.

TAKING TEMPERATURE MEASUREMENTS

Taking a temperature measurement is very easy.
Turn the instrument ON.
Make sure the temperature probe is connected and

allow the reading to stabilize (1 or 2 minutes).
The temperature value will be displayed on the left LCD.

TAKING ORP MEASUREMENTS
(FOR HI 9017 AND HI 9318 ONLY)

HI9017 and HI9318 have the capability to take ORP measurements,

using an ORP electrode. Hanna Instruments offers a variety of ORP
electrodes for this purpose (see page 59). Contact your Dealer for more
information.

Just as pH measurements allow the acidity or the alkalinity of a
substance to be expressed in numbers, oxidation­reduction potential (redox) measurements provide
the quantification of the oxidizing or reducing power
of any liquid.

Connect the ORP electrode to the meter and sub­merge the tip (4 cm / 1½") into the sample to be tested.

Note: ORP measurements are taken without temperature compensa-

tion.
Press the RANGE key once to enter the mV mode.
Allow a few minutes for the reading to stabilize.
The display will indicate the absolute mV value

(positive or negative).
When values are less than ±400 mV, tenths of

mV are displayed; for values greater than ±400
mV, the decimal digit disappears.

Note that the change in scale (from 0.1 mV to 1 mV as resolution) is
automatic.

"Err2" appears if the value exceeds ±1999 mV
(out of range).

IMPORTANT

The instrument's pH range should be re-calibrated:

••

••

• When the meter is new.

••

••

• Whenever the pH electrode is replaced.

••

••

• At least once a month.

••

••

• After testing aggressive chemicals.

••

••

• After cleaning procedure and changing the reference electrolyte.

••

••

• For greatest accuracy.

INITIAL PREPARATION

Pour small quantities (about 4cm / 1½" as level) of pH7.01 (HI7007
or HI8007) and pH4.01 (HI7004 or HI8004) or pH 10.01 (HI7010
or HI8010) solution into clean beakers. If possible use plastic beakers
to minimize any EMC interferences.

If you are measuring in the acid range use pH4.01 as second buffer or
pH 10.01 if you are measuring in the alkaline range.

Note: with HI9017 and HI9318, different pH values can be selected

for calibration purposes. See page 29 and 39 respectively.
For accurate calibration, use two beakers for each buffer solution; the
first for rinsing the electrode, the second for calibration. In this way,
contamination of the buffer is minimized.

When using automatic calibration, the appropriate value will be dis­played. For instance, if the buffer temperature is at 25°C, the display
will show "pH 4.01" or "7.01" or "10.01". If the buffer temperature is
at 20°C, the display will show "pH 4.00"/"7.03"/"10.06". If the
buffer temperature is at 50°C, the display will show pH "4.06"/
"6.98"/"9.82".

The calibration buffer solutions are effected by temperature changes to
a lesser degree than normal solutions.

When manually entering the calibration values (see program #1 for
HI9017 and program #2 for HI9318) please refer to the following chart.

The following section explains how each of the HI 9318's logging
programs work.
Each program has up to 3 functions defined by the A, B and C key.

For program #4, #5 and #6 only, you can log pH or mV values
depending on the RANGE key selection.

PROGRAM #1 (HI9318)

This program allows the user to set sample number, time and date.
Values entered into program 1 are kept in memory even when pro­grams 2 to 9 are used.

To enter program 1:

1) Push the 1 key and then the PGM
key. The printer will then define
the three functions:

A

is the sample num-

ber,

B is time,
C is the date.

2) To set the sample number (A) choose any number from 1 to 999.
Push the desired number followed by the A key and the printer

prints the value.
Samples after 999 will be reset to zero and the sample number
will automatically advance from 0 to 999 in increments of 1, each
time the instrument logs and/or prints a reading.

PROGRAM #2 (HI9318)

This program lets you calibrate with buffer values other than 4, 7 and
10 pH which are pre-programmed into memory.

To enter program 2, press the 2 key
and then the PGM key.

A is the first buffer value and
B is the second buffer value.

The buffers can be anywhere between 0 and 14 pH.

Example:

To calibrate with NBS buffers 6.86 pH and 9.18 pH at a temperature
of 10°C.

The corresponding pH values at this temperature are 6.92 and 9.33
respectively.

Immerse the pH electrode and the temperature probe
into the 1st buffer (e.g. pH 6.86).

Check the appropriate value for the buffer at the
measured buffer temperature (see page 26).

After about 30 seconds enter the 1st buffer value at the working
temperature followed by "A". E.g. 6.92 (at 10°C).

Rinse the electrode and immerse it in the 2nd buffer
(e.g. pH 9.18).

PROGRAM #3 (HI9318)

This program prints the date, time, the offset and slope characteristics
of the pH electrode.

Note: the offset and the slope characteristics of the electrode are

referred to the last performed pH calibration.
No programming is required.
Simply press the 3 key and the PGM

key.
Changes in an electrode's performance
can be determined from this information.
If the electrode's offset is within 0.50 pH and 1.00 pH or -0.50 pH
and -1.00 pH, it indicates contamination. If the value exceeds ±1
pH the electrode should be
replaced.
The slope characteristic is in
percentage of the theoreti­cal value of 58.16 mV per
pH unit at 20°C.

Data transmission from the instrument to
the PC is now much easier with the new
HI92000 Windows® compatible applica-
tion software offered by Hanna Instruments.

User friendly, HI92000 offers a variety of
features and has an on line help feature to
support you throughout all situations.

HI92000 allows you to use the powerful means of the most diffused
spread sheet programs (e.g. Excel©, Lotus 1-2-3©). Simply run your
favorite spread sheet and open the file downloaded by HI92000. It is
then possible to make any elaboration available with your software
(e.g. graphics, statistical analysis).

To install HI92000 you need a 3.5" drive and few minutes to follow
the instructions conveniently printed on the disk’s label.

Contact your Hanna Dealer to request a copy.
To connect your Hanna Instruments bench meter to the PC use

HI920010, available through your Hanna Dealer. Make sure that your
meter is switched off and plug the connectors, one into the meter
RS232C connector, the other into the serial port of your PC.

Note: Cables different from the HI920010 may use a different con-

figuration. In such case any communication between the meter

and the PC is not possible.

SETTING THE BAUD RATE

The transmission speed (baud rate) of the meter and the external
device must be identical. The meter is factory set to 1200.

If you wish to change this value, please contact your nearest Hanna
Center.

SENDING COMMANDS FROM PC

With terminal programs such as, for example, Telix®, Windows Termi­nal®, it is possible to remotely control your Hanna Instruments bench
meter. Use HI920010 cable to connect the meter to the PC, start the
terminal program and set the communication options as follows: 8, N,
1, no flow control.

COMMAND TYPES

To send a command to the pH meter the scheme is:
<DLE> <command> <CR>

Excel© Copyright of "Microsoft Co."
Lotus 1-2-3© Copyright of "Lotus Co."
Windows® and Windows Terminal ® are registered Trademark of "Microsoft Co."
TELIX® is registered Trademark of "Deltacomm"

This line makes the computer send a Data Link Escape character (the
command expressed as a number or a 3-character sequence) and a CR
character.

Note: Windows Terminal® and all the other terminal programs that

support the ANSI escape sequence, represent the DLE character

by the string ‘^P’ and the CR character by the string ‘^M’.

E.g. the line ‘^PPHR^M’ sets the range to pH.

TYPE OF COMMANDS

Commands not requiring an answer from the pH meter.

PHR sets the range to pH
MVR sets the range to mV

Commands requiring an answer:

PH? Causes the pH meter to send the pH value through the serial

interface. If the reading is out of range ("Err1"), "Err1" is sent

instead of the pH value.

If the range is set to mV (no pH reading available), "Err6" is

sent (for HI9218 and HI9219 only).
MV? Causes the pH meter to send the mV value through the serial

interface. If the reading is out of range ("Err2"), "Err2" is sent;

if the range is set to pH, "Err6" is sent.
TM? Causes the pH meter to send the temperature value. If this is

out of range, an "Err3" signal is sent instead.
For HI9218,

HI9219 and

HI9318 only:

HM? This orders the pH meter to send the time value (in hours and

minutes), A 5-character string is sent in HH.MM format.
MD? This orders the pH meter to send the data value (in months and

days). A 5 character string is sent in MM.DD format.
These commands may be sent with either capital or small letters. The

characters sent by the meter are always capital letters.
For HI9318 only:
a) Numerical data: a command line containing figures , the minus

sign and the decimal point will be interpreted by the pH meter as
if that number was sent by means of the keyboard. The maximum

number of figures allowed is 4.
b) Commands which do not require a response by the pH meter:
CAL is equivalent to pressing the CAL key
CON is equivalent to pressing the CON key
AKY is equivalent to pressing the A key

Windows Terminal ® is registered Trademark of "Microsoft Co."

48

BKY is equivalent to the B key
CKY is equivalent to pressing the C key
PGM is equivalent to pressing the PGM key
TEM is equivalent to pressing the TEMP key
PRT is equivalent to pressing the PRINT key
CLR is equivalent to pressing the CLEAR key
PHR brings the instrument into pH measurement range
MVR brings the instrument into the mV measurement range
PAP causes the paper to advance by one tenth of a line. In order to

advance the paper by one entire line, send a RETURN charac-

ter.
TIM causes the time to be shown on the date/time display
DAT causes the date to be shown on the date/time display
CHP sets the printer in the character printout mode
PPR sets the printer in the graph printout mode
KBS after this command, the keys pressed on the pH keyboard are

no longer recognized by the pH meter itself, but instead pro-

voke the transmission of a string to the host computer. Only the

OFF and the PAPER keys retain their proper functions. In this

way, the keyboard may also function as an input device to the

host computer, as well as command the pH meter.

Naturally the pH meter continues to obey the commands which

are equivalent to the keys pressed and sent by means of serial

interface.
KBU cancels the KBS command

The 4 commands IDL, SEP, SEV and RV? are reserved for future use
and are not described here.

INTERFACE WITH PC

If you are not using Hanna Instruments HI92000 application soft­ware, please find here below some additional information to help your
connection to the PC.

HOW TO CHANGE THE COMMAND PREFIX CHARACTERS
(FOR HI9017 & HI9318 ONLY)

It is sometimes necessary to change the character used to indicate that
a command is to follow.

If the computer connection already makes use of DLE of other func­tions, its use as a prefix for "c"-type commands may cause problems to
the operating system.

In order to change the prefix character run program #6 for HI9017,
by pressing the 6 key and then the PGM key or run program #9 for

49

HI9318 by pressing the 9 key and then the PGM key.
Enter the ASCII Code of the desired prefix character and then press the

ENTER A key for HI9017 or the A key for HI9318.
It is advisable to use a control character as a prefix (not RETURN,

which already performs other functions) or a non-control character
which is not being used for other purposes, for example the "@" sign
(ASCII Code64).

MORE ABOUT KBS COMMAND (FOR HI9318 ONLY)

The KBS Command (KeyBoard Send) disconnects the keyboard from
the pH meter and connects it to the RS 232C interface.

Whenever a key is pressed on the keyboard, a string of characters
which represents the key itself is sent by means of interface, followed
by a RETURN character.

The strings corresponding to the various keys are the following:

- the figures from 0 to 9 for the numbered keys;

- the minus sign (-) for the +/- key;

- the full stop (.) for the decimal point.
The other keys (CAL, CON, A, B, C, DATE, RANGE, PGM, TEMP, PRINT

and CLEAR) are represented by their own abbreviations.
The OFF and PAPER keys maintain their own functions and are not

sent to the computer.

GRAPHIC PRINTOUT (FOR HI9318 ONLY)

The HI 9318 printer may also be programmed for graphic mode
printing for the reproduction of bit graphs and maps: every 16 bytes of
data received from the pH meter produce an elementary line of dots
rather than a line of text.
In order to print one or more lines of dots (96 dots per line), the
computer must first send the PPR command to set the printer in the
graphic mode, then:

- divide the 96-dot line into 16 segments of 6 dots long,

- interpret each segment as a binary number (the left most dot will

be the most significant bit),

- add hexadecimal 20 or decimal 32 to each binary number and

- send the 16 numbers as 16 characters.

50

PREPARATION

Remove the protective cap.
DO NOT BE ALARMED IF ANY SALT DEPOSITS ARE PRESENT.
This is normal with electrodes and they will disappear when rinsed

with water.
During transport tiny bubbles of air may have formed inside the glass

bulb. The electrode cannot function properly under these conditions.
These bubbles can be removed by "shaking down" the electrode as
you would do with a glass thermometer.
If the bulb and/or junction are dry, soak the electrode in HI70300 or
HI80300 Storage Solution for at least one hour.

For refillable electrodes:

If the filling solution (electrolyte) is more than 1 cm (½") below the
fill hole, add HI7082 or HI8082 3,5M KCl Electrolyte Solution for
double junction or HI7071 or HI8071 3,5M KCl+AgCl Electrolyte
Solution for single junction electrodes.

For a faster response, unscrew the fill hole screw during measure­ments.

For AmpHel electrodes:

If the electrode does not respond to pH changes, the battery is run
down and the electrode should be replaced.

MEASUREMENT

Rinse the electrode tip with distilled water.
Immerse the tip (4 cm /1½") in the sample and stir gently for at least

30 seconds.
For a faster response and to avoid cross contamination of the samples,

rinse the electrode tip with a few drops of the solution to be tested,
before taking measurements.

STORAGE

To minimize clogging and assuring a quick response time, the glass
bulb and the junction should be kept moist and not allowed to dry out.

Replace the solution in the protective cap with a few drops of HI70300
or HI80300 Storage Solution or, in its absence, Filling Solution
(HI7071 or HI8071 for single junction or HI7082 or HI8082 for
double junction electrodes).

Follow the Preparation Procedure above before taking measurements.

Note: NEVER STORE THE ELECTRODE IN DISTILLED WATER OR DRY.

PERIODIC MAINTENANCE

Inspect the electrode and the cable. The cable used for connection to
the meter must be intact and there must be no points of broken
insulation on the cable or cracks on the electrode stem or bulb.
Connectors must be perfectly clean and dry.

If any scratches or cracks are present, replace the electrode.
Rinse off any salt deposits with water.

For refillable electrodes:

Refill the reference chamber with fresh electrolyte (HI7071 or HI8071
for single junction or HI7082 or HI8082 for double junction elec­trodes). Allow the electrode to stand upright for 1 hour.
Follow the Storage Procedure above.

52

CLEANING PROCEDURE

General Soak in Hanna HI7061 or HI8061 General Cleaning
Solution for approximately 1 hour.

Removal of films, dirt or deposits on the membrane/junction:

- Protein Soak in Hanna HI7073 or HI8073 Protein Cleaning So-
lution for 15 minutes.

- Inorganic Soak in Hanna HI7074 or HI8074 Inorganic
Cleaning Solution for 15 minutes.

- Oil/grease Rinse with Hanna HI7077 or HI8077 Oil and

Fat Cleaning Solution.
IMPORTANT: After performing any of the cleaning procedures rinse

the electrode thoroughly with distilled water, drain and refill the
reference chamber with fresh electrolyte, (not necessary for GEL filled
electrodes) and soak the electrode in HI70300 or HI80300 Storage

Solution for at least 1 hour before taking measurements.

TROUBLESHOOTING

Evaluate your electrode performance based on the following.

• Noise (Readings fluctuate up and down) could be due to:

- Clogged/Dirty Junction: Refer to the Cleaning Procedure above.

- Loss of shielding due to low electrolyte level (in refillable elec-

trodes only): refill with fresh HI7071 or HI8071 for single junction
or HI7082 or HI8082 for double junction electrodes.

• Dry Membrane/Junction: Soak in Storage Solution HI70300

or HI80300 for at least 1 hour.

• Drifting: Soak the electrode tip in warm Hanna Solution HI7082

or HI8082 for one hour and rinse tip with distilled water. Refill
with fresh HI7071 or HI8071 for single junction electrodes and
HI7082 or HI8082 for double junction electrodes.

• Low Slope: Refer to the cleaning procedure above.

• No Slope: Check the electrode for cracks in glass stem or bulb

and replace the electrode.

• Slow Response/Excessive Drift: Soak the tip in Hanna Solution

HI7061 or HI8061 for 30 minutes, rinse thoroughly in distilled

water and then follow the Cleaning Procedure above.

The resistance of glass electrodes partially depends on the temperature.
The lower the temperature, the higher the resistance. It takes longer time
for the reading to stabilize if the resistance is higher. In addition, the
response time will suffer to a greater degree at temperatures below 10°C.

Since the resistance of the pH electrode is in the range of 200 Mohm,
the current across the membrane is in the pico Ampere range. Large
currents can disturb the calibration of the electrode for many hours.
For these reasons high humidity environments, short circuits and
static discharges are detrimental for a stable pH reading.

The pH electrode's life also depends on the temperature. If constantly
used at high temperatures, the electrode life is drastically reduced.

Typical Electrode Life
Ambient Temperature 1- 3 years
90 °C Less than 4 months
120°C Less than 1 month

High concentrations of sodium ions interfere with readings in alkaline
solutions; the pH at which the interference starts to be significant
depends upon the composition of the glass. This interference is the
alkaline error and causes the pH to be underestimated. Hanna's glass
formulations have the indicated characteristics.

Recommendations for Users

Before using these products, make sure that they are entirely suitable for the environ­ment in which they are used.

Operation of these instruments in residential area could cause unacceptable interfer­ences to radio and TV equipments, requiring the operator to take all necessary steps to
correct interferences.

The glass bulb at the end of the electrode is sensitive to electrostatic discharges. Avoid
touching this glass bulb at all times.

During operation, ESD wrist straps should be worn to avoid possible damage to the
electrode by electrostatic discharges.

Any variation introduced by the user to the supplied equipment may degrade the
instrument's EMC performance.

To avoid electrical shock, do not use these instruments when voltages at the measure­ment surface exceed 24VAC or 60VDC.

To avoid damages or burns, do not perform any measurement in microwave ovens.
In particular cases HI9017 could turn off. In such cases, turn it on by pressing the ON

key.
