The Model H-810BL is supplied with a 2 inch wide, 6 foot long belt for carrying
purposes or for hanging the instrument during sampling. The instrument is not designed
to be suspended by the power cord.
METHOD OF OPERATION
Operation of the H-810BL is simplified through the use of English-language prompts on
a digital display. After turning the unit ON, the display will prompt for the calibrated
range desired. After selecting either 1, 2, or 3 the selected calibration range will be
displayed (note: 1, 2, or 3 will only appear if a multi-calibration unit was purchased).
Pressing CLEAR at this point will return to the select calibration 1, 2, or 3 display.
Pressing any other key on the keypad will cause the unit to indicate the current preset
volume or time. At this point a sample may be initiated by pressing the START key, or
the preset may be changed by pressing the SET key. i.e.:
CALIBRATED RANGE to
1, 2 or 3?
Calibrated Range to Target Volume: or Target Run Time:
4.0 to 6.0 CFM 1000 ft3 10:00
After pressing the SET key, the display will prompt for a new target time or volume,
depending on the current mode of operation selected during the last calibration. i.e.:
Enter Target or Enter Target or Enter Target
Time: 00:00 Volume 0 ft3 Volume 0 lit
Enter a new value using the digit keys followed by ENTER, or press ENTER to cancel
changing the target.
The H-810BL is equipped with KEYPAD SECURITY. With this feature enabled, the
SET function on the keypad is disabled, preventing the operator from altering the preset
sample time or volume. This feature also inhibits the display of the current calibrated
range upon power-up.
