4.2 Calibration Menu [.CAL.]

InCal or Span calibration should be performed daily and when the room temperature changes.

InCal [InCal] calibrates the balance using an internal mass.

Span Calibration [SpaN] uses two weight values: zero and a weight between 50% and 100% of the capacity of the

balance.

Linearity calibration [LIN] uses three weight values zero, 50% of capacity and full capacity. Generally this

calibration is not required unless testing shows that the linearity error exceeds the Linearity tolerance in the

Specification table. (Not available in InCal models)

Calibration Adjust [CAL Adj] allows adjustment to the result of the internal calibration by +/- 99 divisions.

(InCal models only)

4.3 Setup Menu [.setup.]

Automatic Zero-Setting [azsmM] – Environmental changes can cause the display to drift. The Automatic Zero-

Setting Mechanism (AZSM) is designed to keep the balance set at zero, despite these slight changes. (OFF,

SET.5d, SET 1d, SET 2d, SET 5d)

Filter [filter] – Use the low setting (SET LO) when environmental disturbances are not present. Use the

medium setting (SET MED) for normal environments. Use the high setting (SET HI) when vibrations or air currents

are present.

Auto Tare [A-tare] – The initial item placed on the balance is assumed to be a container so it is zeroed out. The

next item is then weighed. When the pan is cleared the balance resets, waiting for a container. (SET OFF, SET

ME (Mesghal).

Custom Unit – Custom Unit (C) is used to create a unit of measure not provided with the balance. The Custom Unit

is defined by a factor, a multiplier (E) and a least significant digit (LSD). The balance will use this to convert grams

to a custom unit of measure. (Example: 1 gram = 0.257206 Avoirdupois Dram, using a 4100g x 0.01g balance)

To create a custom unit, press Yes when unit [c] is displayed.

Factor – The Factor (F) is a value from 0.1000000 to 1.999999. When the Factor is displayed, the first digit is

flashing. Press Yes to accept its value and activate the next digit, or No to edit. When editing, press No until the

desired value appears, then press Yes to accept. Repeat until all digits have been accepted. When the Factor

flashes on the display, press Yes to accept or No to re-edit. (Example: F = 0.257206)

Multiplier (E) – The settings are, [E 0] (Fx1), [E 1] (Fx10), [E 2] (Fx100), [E 3] (Fx1000), [E-3] (F/1000),

[E-2] (F/100), and [E-1] (F/10). Press No to display the next setting, Yes to accept. (Example: E = 0).

Note: The multiplier selections are limited when the capacity in grams is exceeded.

LSD – The Least Significant Digit (LSD) is the number of displayed divisions (d) by which the weight is

incremented. The values are 1d, 2d, 5d, 10d, 100d or 0.5d. Press No to go to the next setting, press Yes to accept.

(Example LSD = 1d) Note: LSD options are limited if the readability in grams is exceeded.

The example custom unit will display [0.26 C] when 1g is placed on the pan.
