Introduction

Benchtop level analysis in the eld! Reads either pH (in 0.01 resolution) or mV in large digits, with time, date, and tem­perature (in °C or °F) shown simultaneously on the lower display. Also indicates stable reading, low battery and displays
calibration data. Scroll 99 data points with time stamps and min/max readings directly on the backlit LCD.

Features:

• Multi-display LCD screen

• 5 points pH calibration

• N.I.S.T. buffer recognition

• Maximum and minimum

• Hold function

• Backlight for dark environment operation

• Easy to view probe calibration data

• “Ready” icon on LCD display indicates stability for reading

• USB connection for online logging and uploading 99 mem-

ories to PC for analysis

• Automatic or manual temperature compensation

• External power adapter (optional) for long use testing

• Auto power off to save battery

LCD Display

• HLD Holds the current reading on the dis-

play.

• ATC means the meter is in automatic tem­perature compensation mode.

• MAX, MIN indicate maximum or minimum
memory value.

• READY indicates the reading is stable.

• CAL indicates the meter is in calibration

mode.

• REC indicates the meter is in recall mode.

Press to turn meter on/off. Press and hold

for more than 1 second to enter SET mode.

Switch between NORMAL and CALIBRA-

TION mode Press to enter manual tem-

perature setting. In calibration, setting or

Setup Mode

The advanced Setup Mode allows you to customize the following meter preferences and defaults:

2

P 1.0 Memory Transmission
P 2.0 Clear Memory
P 3.0 Electrode (pH probe)
P 4.0 Buffer Solution (pH)

P 5.0 Ready Function
P 6.0 Temperature Units
P 7.0 Real Time Clock
P 8.0 Reset

P 1.0 Memory Transmission – transfers stored data from the meter to the computer

NOTES: R To enter Setup Mode, press SET for about 2-3 seconds while the meter is in Normal Mode.
R To exit Setup Mode without saving, press ESC until the Normal Mode appears.
R If the meter is in Setup Mode, press ESC twice to exit.

1. Connect USB cable to the right side of the meter and connect the other end of the cable
with the D-sub connector to the computer’s serial port. Run the software associated with
this feature.

2. Press SET for 2 seconds to enter setup.

3. The “TR” icon appears on the middle of the LCD display and P1.0 displays under the “TR” icon.

4. Press MN/MX/AV. The “OUT” icon ashes on the upper display and P1.1 displays under
the “OUT” icon. This indicates that the memories are transferring. After transmission, the
LCD will return to P1.0.

NOTE: The meter can store up to 99 records for each parameter. To transmit data for a differ­ent parameter, press ▲ to select desired parameter before entering setup.

P 2.0 Clear Memory

The memory clear program is designed to clear 99 memories at one
time. Proceed cautiously, as this operation cannot be reversed.

Press MODE to select the parameter you want cleared before entering Setup Mode.

1. Press SET for 2 seconds to enter setup.

2. Press ▲ to select memory clear function.

3. The “CLR” icon appears on the middle display and P2.0 illuminates in the lower display.

4. Press MN/MX/AV to enter P2.1.

5. The default “NO” icon ashes on the middle display and P2.1 appears in the lower dis-

play.

6. Press ▲ to change the status from “NO” to “YES” and then press MN/MX/AV again to

conrm clearing of all memory. The LCD display will return to P2.0 when memories are

deleted.

Setup Mode, continued

P3.0 View Slope & Offset

Press MODE to select the parameter you want cleared before entering Setup Mode.

1. Press MODE to select probe type as pH.

2. Press SET for 2 seconds to enter setup.

3. Press ▲ until the icon “ELE” appears in the middle display and
P3.0 appears in the lower display.

4. Press MN/MX/AV to enter P3.1, the LCD displays one of four
available slope values; P3.1, P3.2, P3.3, P3.4. If the value is less

than 75% or more than 115%, change the probe immediately.

5. Press MN/MX/AV to enter P3.2, P3.3, and P3.4.

NOTE: The solution range denition differs between NIST and Cus-
tom buffers.

Solution Range

Buffer P3.1 P3.2 P3.3 P3.4

NIST 0.00 ~ 4.01 4.01~ 6.86 6.86~9.18 9.18~14.00

3

Custom 0.00 ~ 4.50 4.50~7.00 7.00~9.50 9.50~14.00

6. Press MN/MX/AV to enter P3.5 and view the offset value. The offset value is the mV value of pH 7 and the default
offset value is 0.0. The offset value will be different after calibration. If the value is outside the range of ± 60 mV,
replace the probe.

P4.0 pH Calibration Buffer

This meter allows the selection of two different types of pH buffers: NIST or CUSTOM. Selection of the proper buffer type

more accurately calibrates the probe to specic requirements.

NIST buffer has ve settings:

R

pH 1.68, 4.01, 6.86, 9.18, 12.45

CUSTOM buffer has ve ranges:

R

pH 1.00-3.00, 3.50-5.50, 6.00-8.00, 8.50-10.50, 11.50-13.50

Select Buffer

1. Press SET for 2 seconds to enter setup.

2. Press ▲ to select pH buffer. “BUF” will appear on the middle of the LCD and P4.0 will

appear on the lower portion.

3. Press MN/MX/AV to enter P4.1. The default “NIS” (NIST) will ash on the LCD and P4.1

will appear on the lower portion of the display. If you use N.I.S.T. buffers, press MN/MX/

AV to conrm and the meter returns to P4.0.

4. If your requirement is not for NIST buffers, press ▲ to change the status to CUSTOM

buffer.

5. Press MN/MX/AV to conrm and the meter will return to P4.0.

digits only; for example, 1999 would be 99).

Symbol: Y-M-D H:M:S

Denition: Yr.-Mo.-Day Hr.-Min.-Sec.
Range: 99-12-31 23-59-59

4. Press MN/MX/AV to step through the following “P’s.” All are two digits.
