display the stored calibration for the load cell to which the external memory is connected. The
external memory does not return
ECAL
and
ESCL
values to the HH4-WT therefore the
ECAL
and
ESCL
values in the HH4-WT will be those of the last cell calibrated, not necessarily those of
the cell connected. Do not view the
ECAL
and
ESCL
settings when external memory is connected
unless you wish to recalibrate the load cell since the calibration slope information for these settings
will be overwrite the calibration slope in the external memory chip.

for details of electrical wiring for the memory device. Calibration and setup with external
memory The calibration and setup procedures are identical those described in the “Explanation of
functions” chapter. If connected to a load cell with an external memory device then you simply
need to ensure that the channel you wish to calibrate (
CH.A1
) is selected prior to any calibration
or setup. The
CH.A1
channel should automatically be selected when the HH4-WT detects that a
memory device is connected. Taking readings with external memory Once the load cell with external
memory is connected to the HH4-WT the instrument will automatically display the calibrated
scaling figures for that load cell. Simply ensure that the required channel (
CH.A1
) is selected prior
to taking a reading. The
CH.A1
channel should automatically be selected when the HH4-WT
detects that a memory device is connected.
