Time
The Mudtest stopwatch helps to perform the Marsh funnel test and
to measure time intervals during tests of fresh concrete and grout.

Description
The Mudtest timer is a classic stopwatch that can also be used to record
split times. This makes the Mudtest stopwatch ideal for measuring viscos-
ity with the Marsh funnel in accordance with API 13B-1 and to measure
the time for the drilling uid to ll to 946ml (1quart) mark of the cup.
Because the timer or clock has a resolution higher than 0,5 s, it also meets
the tighter tolerance specications of the EN 12350 series of standards
and can be used for examining fresh concrete.
The Mudtest stopwatch even satises the requirements of EN 445 and the
test methods of grout for prestressing tendons, since the uidity test with
the cone requires a stopwatch showing time to 0,1 s.
The stopwatch shows the time in 12/24h time format, has an alarm func-
tion and a calendar. The stopwatch is splash-proof. The battery lock on
the back can be opened without a screwdriver.
The Mudtest stopwatch is suitable for tests according to the following
standards, among others:
• NF P 18-507
• DIN 4127
• DVGW W 116
• EN 12350
• EN 445
• API 13B-1 / ISO 10414-1
• API 13B-2 / ISO 10414-2

Pressing the SPLIT/RESET button displays the time for the alarm clock.
If you hold down the SPLIT/RESET button and press the START/STOP but-
ton at the same time, you can switch the alarm function on or off. A small
bell will appear on the display depending on the activity status. If there is
an H next to the alarm time, it means that the clock is running in 24-hour
mode. An A stands for AM and a P stands for PM when the watch is set to
12 hour mode.
If you hold down the SPLIT/RESET button and press the MODE button at
the same time and several times, you can specify whether the alarm clock
should ring daily at the set time or just once. The alarm clock rings daily
when all days of the week are displayed. If there are no days of the week
in the top row of the display, then the alarm will only ring once.
SU = Sunday
MO = Monday
TU = Tuesday
WE = Wednesday
TH = Thursday
FR = Friday
SA = Saturday
Stopwatch
You can access stopwatch mode by pressing the MODE button once.
Start the time measurement by pressing the START/STOP button. If you
now press the START/STOP button again, you interrupt the time measure-
ment. If you press the START/STOP button again, the time will continue.
The stopwatch can be reset by pressing the SPLIT/RESET button.
To determine intermediate times, rst press the START/STOP button.
When an intermediate time is reached, press the SPLIT/RESET button. The
split time is now displayed to you, while the stopwatch continues to run in
the background. If you now press the SPLIT/RESET button again, the dis-
play jumps to the elapsed time. Caution: The stopwatch has no memory.
So you must write down the split times before you press the SPLIT/RESET
button again. Stop the measurement by pressing the START/STOP button.
Alternatively, you can determine other intermediate times.
For series of measurements that only require an intermediate time, pro-
ceed as follows: Press the START/STOP button to start the measurement.
When the rst event for which you need a time measurement has oc-
curred, press the SPLIT/RESET button. Once the second event for which
you need a time measurement has occurred, press the START/STOP but-
ton. The display continues to show the split time. The total time is only
displayed if you press the SPLIT/RESET button again. This method is suit-

able, for example, for determining hopper discharge times, in which a dis-
tinction is made between discharge time and remaining discharge time.
After pressing the START/STOP button, you can tidy up in peace and re-
cord the values later in the site ofce. But be careful here too: As soon as
you press the SPLIT/RESET button, the intermediate time is gone.
Pressing the MODE button takes you back to the time, date, alarm clock
view.
Adjusting the alarm clock
You can access the mode for adjusting the alarm clock by pressing the
MODE button twice.
Note that the alarm clock turns on and off in the Time, Date, Alarm clock
view. In this mode, only the time for the alarm clock is adjusted.
You can toggle between the hours and minutes by pressing the SPLIT/
RESET button.
You can change the time for the alarm clock by repeatedly pressing the
START/STOP button.
By pressing the MODE button, the alarm clock settings are saved and you
return to the time, date, alarm clock view.
Adjusting the time and date
You can access the mode for adjusting the time and date by pressing the
MODE button three times.
You can toggle between seconds, minutes, hours, days and months by
pressing the SPLIT/RESET button.
You can set seconds, minutes, hours, days and months by repeatedly
pressing the START/STOP button. You can achieve fast counting up by
holding down the START/STOP button.
By pressing the MODE button, the settings are saved and you return to
the time, date, alarm clock view.

Maintenance and Care
The Mudtest stopwatch requires little maintenance. Please pay attention
to cleanliness and proper storage. Store the stopwatch in a dry place and
avoid contact with corrosive media. Avoid direct sunlight and bright light
over a long period of time, as the quality of the display will suffer.
Battery change
If the characters on the display become faint or illegible, please change
the battery. To do this, you can open the round cover on the back of the
stopwatch, e.g. with a 20 cent coin, change the battery and screw the co-
ver tight again.

Disposal of the electrical device
Remove non-permanent batteries and rechargeable bat-
teries from the device and dispose of them separately.
This device is labeled in accordance with the EU Waste
Electrical and Electronic Equipment (WEEE) Directive.
This product must not be disposed of with household
waste. The user is obliged to hand in the old device for
environmentally friendly disposal at a designated accep-
tance point for the disposal of electrical and electronic
devices. Observe the currently applicable regulations!
Disposal of the batteries
Batteries and accumulators must never be disposed of
with household waste. They contain pollutants such as
heavy metals, which can be harmful to the environment
and health if not disposed of properly, and valuable raw
materials such as iron, zinc, manganese or nickel, which
can be recovered.
As a consumer, you are legally obliged to hand in used
batteries and accumulators for environmentally friendly
disposal to retailers or to appropriate collection points in
accordance with national or local regulations. The return
is free of charge. Addresses of suitable collection points
can be obtained from your city or local government.
The designations for the heavy metals contained are:
Cd=cadmium, Hg=mercury, Pb=lead.
Reduce battery waste by using longer life batteries or
suitable rechargeable batteries. Avoid littering the envi-
ronment and do not leave batteries or electrical and elec-
tronic equipment containing batteries lying around. The
separate collection and recycling of batteries and accumu-
lators makes an important contribution to protecting the
environment and avoiding health hazards.
