Draminski GRAIN MOISTURE METER, Instruction Manual

. Working according to manual will enable to ob-
tain expected accuracy and recurrence in mois-
ture measurement.
It is recommended to make three measurements. The
avearge of three measurements is the final result.
. Temperatures of sample and instrument should be
similar (sensor reacts with some delay).
3. Cleanness of sample for measurement has an in-
fluence on obtaining accurate result. Sample
should not contain husks, tailings and dirti-
nesses.
. You should check if there are no seeds in measure-
ment chamber before work. You should remove
any remainings from earlier measurement from the
chamber.
Before turning on an instrument meas-
urement chamber should be clean and empty.
. The way of filling the measurement chamber is
important and may influence precision of meas-
urement results.
. Producer suggests using alcaline batteries. The
electrolite which comes out of ordinary battery
after exhausting may damage the device. Alcaline
battery works longer and there is no risk of outflow
of electrolite.
. When the limit ranges of measurement are ex-
ceeded the display shows:
“<%” (below range), when moisture of measured
sample is lower than %.
“>3,0%” (above range), when moisture of measured
sample is higher than 3%.
. If important variations of readings appear in com-
parison with laboratory results of the samples, you
should use modification mode (
see the chapter 4:
“DATA MODIFICATION” ).
