Measuring procedure
Step 1 Confirm thatthe balance is in the mode to measure
the weight of the sample in air. (" g" displayed and
processing indicator flashing)
Step 2 Confirm that the balance indicates zero. If it does
Step 3
not indicate zero, press the RE-ZERO key to reset
the displayed value to zero.
Place the sample on the upper pan (in air). When
the value displayed on the balance becomes stable,
Note
Step 4
press the [RANGE key to confirm the value (the
weight of sample in air). The balance enters the
mode to measure the weight of sample in liquid (
" g " displayed and processing indicator illuminat
ing).
If a negative value or E (error) is displayed, the
RANGE key is disabled.
Place the sample on the lower pan (in liquid). When
the value displayed on the balance becomes stable.
press the [RANGE key to confirm the value (the
weight of sample in liquid). The balance enters the
mode to display the density (" g " not illuminated).
Note
Step 5
If E (error) is displayed, the [
range
! key is
disabled.
To output or save the density, press the [PRINT
key. The unit for outputting the density is " DS ".
To measure the density of another sample, press
the [RANGE key to return to the mode to measure
the weight in air and repeat the procedure de
scribed above.
Note : If the liquid temperature or the type of liquid is
changed during measurement, reset the value
of the liquid density as necessary. For details,
see " Setting the density of a liquid ".
