INTRODUCTION
The Sper Scientic PH SD Card Datalogger (Model 850060)
is an intelligent meter that reads pH and mV.
This meter has a wide variety of applications in industries
such as water conditioning, aquariums, sh hatcheries, food
processing, photography, laboratory, paper, plating, quality
control, and science education.
This meter features a real time SD memory card datalogger.
Standard, portable SD memory cards provide unlimited data
storage and upload pre-formatted data directly to Excel,
eliminating the need for cables or software. Alternatively,
manually record 99 readings for on-screen review or stream
data directly to a computer using the optional software and
cables. Each data set includes pH or mV measurement, time
and date.

SD Memory Card Format
Enabling this function will format the SD memory card to work
specically with your meter. Formatting the SD card will erase
any previous memory on the card. New SD cards should be
formatted to work with your meter.
1. Enter the SD memory card format function from Setup
Mode (see page 8). “Sd F” appears on the LCD.
2. Press ▲ or ▼ to select yes (format the SD memory card)
or no (do not format the SD memory card). Press ENTER
to conrm your selection. If selecting yes, “yES Enter” will
appear on the LCD, press ENTER again and the meter will
format the SD card.
Real Time Clock
1. Enter the clock function from Setup Mode (see page 8).
“dAtE” appears on the LCD.
2. Press ENTER. The year will ash on the LCD.
3. Press ▲ or ▼ to adjust the value. Press ENTER to save
the value.
4. Repeat Step 3 to adjust the month, date, hour, minute
and second.
5. Press SET to complete the clock setup function.
Note…
This procedure adjusts the meter’s internal clock. The internal
clock will function when the meter is turned o󰀨 but only when
the batteries have adequate power (not with low battery power.)

10
Sampling Time
The sampling time (hour/minute/second) is the time allotted
between successive measurements. To adjust the sampling time:
1. Enter the sampling time function from Setup Mode (see
page 8). “SP-t” appears on the LCD.
2. Press ▲ or ▼ to adjust the value (starting with the hour
value). Press ENTER to save the value. The meter will
advance to the next value adjustment (minute, second).
3. Repeat Step 2 until the setting is complete.
4. Press SET to save the value.
Auto Power O󰀨
The meter automatically turns o󰀨 after 10 minutes of inactivity,
however this function can be disabled.

page 8). “PoFF” appears on the LCD.
2. Press ▲ or ▼ to select yes (auto power o󰀨 enabled) or no
(auto power o󰀨 disabled). Press ENTER to save the selection.
Touch-Tone
1. Enter the touch-tone function from Setup Mode (see page
8). “bEEP” appears on the LCD.
2. Press ▲ or ▼ to select yes (touch-tone enabled) or no
(touch-tone disabled). Press ENTER to save the selection.

11
Decimal Type
Although the decimal is commonly expressed as the “.”
symbol (i.e., 20.6 or 1000.53), some (European) countries use
a “,” symbol to represent the decimal (i.e., 20,6 or 1000,53).
The meter defaults to the period symbol. To adjust:
1. Enter the decimal type function from Setup Mode (see page
8). “dEC” appears on the LCD.
2. Press ▲ or ▼ to select Basic (.) or Euro (,). Press ENTER
to save the selection.
Temperature Units
1. Enter the temperature units function from Setup Mode (see
page 8). “t-CF” appears on the LCD.
2. Press ▲ or ▼ to select C (degrees Celcius) or F (degrees
Fahrenheit). Press ENTER to save the selection.
Manual Temperature Compensation Value (pH only)
1. Enter the manual temperature compensation function from
Setup Mode (see page 8). “t-SEt” appears on the LCD.
2. Press ▲ or ▼ to adjust the value to the desired selection
(in °C or °F). Press ENTER to save the selection.
Note…
After completing this function, press SET to advance to the
next function. “ESC” appears on the LCD. Press ESC to
complete the setup procedures and return to Normal Mode.

12
CALIBRATION
This meter has been calibrated using a pH probe with an ideal
reading: generates 0 mV at pH 7.00 (177.4 mV at pH 4) in an
ambient temperature of 25°C. Because your probe may not be
ideal, calibration is necessary before rst time use. For best
results, calibrate your meter weekly. For the highest accuracy,
we recommend a two point calibration. Begin with pH 7 (then
calibrate pH 4 or 10).
To calibrate:
1. Prepare the probe for calibration (see page 12).
2. Using a standard pH and/or ATC probe, plug the probe plug
into the pH probe socket.
3. Press POWER to turn the meter on.
4. For the standard pH probe only (not ATC): Adjust the
manual temperature compensation value to the same value
as the solution temperature. (See page 11).
5. Select the pH bu󰀨er and pour solution (a su󰀩cient amount
to totally immerse the probe tip) into a clean container.
6. Dip the probe into the container, immersing the probe tip.
Gently shake the probe.
Note…
If calibrating the ATC probe with the pH probe, dip the probes
in the solution simultaneously.
7. The pH value appears on the LCD.

8. Press REC and HOLD simultaneously until “PH” appears
on the display.
9. Press ▲ or ▼ in sequence to select the following screens:

to the same value as the solution
temperature. (See page 18.)
5. Select the pH buffer and pour
solution (a sufficient amount to
totally immerse the probe tip) into
a clean contai ner.
6. Dip the probe into the container,
immersing the probe tip. Gently
shake the probe.
Note…
If calibrating the ATC probe with the
pH probe, dip the probes in the
solution simultaneously.
7. The pH value appears on the
LCD.
8. Press REC and HOLD
simultaneously until “PH” appears
on the display.

Selecting the Function
Press and hold FUNC to cycle through the options listed
below. Release FUNC when you reach the desired function.
• pH
“pH” appears on the LCD.
• mV
“mV” appears on the LCD
Defaults
The meter will default to the following settings:
• pH
• °C
• Manual ATC (without connecting the ATC probe)
• Auto power o󰀨
• Datalogger sampling time: 2 seconds

16
Preparing the pH/ORP Probe
1. Remove the pH or ORP probe soaker bottle by rotating the
bottle and cap and slide the bottle and cap o󰀨 the probe.
2. Rinse the probe tip with de-ionized or distilled water before use.
Note…
If the probe tip is dehydrated, soak it for 30 minutes in a KCl
solution. DO NOT wipe the pH probe dry. Wiping the probe
may cause static and cause measurement instability.
