1.1
Automatic Zero Tracking - Enable / Disable
(command ZT)
-
Setting range
: 0 … 255 d
Disabled @ 00000, no ZERO Tracking
Enabled @ 00001 or higher (max 00255)
-
Setting 00001 sets a zero tracking range of ±0.5d
-
Setting 00002 up to 00255 sets a zero track range of
±1d up to ±127.5d, independent of decimal point setting
1.2
Calibrate system ZERO - gravimetric by weight / load
(command CZ)
-
Display shows the actual input signal in mV/V.
Press ENTER button to store ZERO.
Remark:
Scale should/must be unloaded.
1.3
Calibrate system ZERO - electronic by mV/V value
(command AZ)
-
Use the UP/DOWN & MOVE RIGHT keys to setup the mV/V value
at which the device should read ZERO
1.4
System ZERO & TARE function
1.4.1
Store TARE value non volatile: ON / OFF
(command TN)
-
ON: store non-volatile @ power OFF
-
OFF: delete @ power OFF
1.4.2
Store ZERO value non volatile: ON / OFF
(command ZN)
-
ON: store non-volatile @ power OFF
-
OFF: delete @ power OFF
1.4.3
Initial ZERO @ power ON: ON / OFF
(command ZI)
-
ON: proceed initial Zero @ power ON
-
Range is ±10% of Max
1.4.4
ZERO range (increments)
(command ZR)
-
-
-
Set the zero setting range in divisions.
The setting is independent of decimal point setting.
Disabled @ 00000, no ZEROing possible
Enabled @ 00001 or higher (max 999999)
In a legal for trade application, the standard value is ±2 % of Max.
The setup for a scale with 3 000e is i.e.:
-
Max (CM) = 1 500 kg
-
Step Size (SZ) = 0.5 kg
-
Zero Range (ZR) of ±2 % = ± 30 kg, which is ± 60 d.
