Common accidents in weighing 1: Spillage
Weighing of powder or liquid materials for filling, formulating, etc., always carries a risk of spillage, which could damage the balance.
IP65 dust and waterproof A&D Apollo High Capacity balances, which are IP65 rated, permit no ingress of dust, and can withstand water projected from any direction, as defined by the IEC/EN standard 60529.

Common accidents in weighing 2: Impact shocks
The weight sensor of a high-precision balance will be damaged if continually affected by loads with acceleration (impact shocks). This typically occurs in factories where objects are placed roughly by machines or operators onto balances. In addition, impact shocks can easily shift values and cause errors.
Impact shock detection (ISD)
Impact-Alert
A&D Apollo High Capacity balances visualize the magnitude of impact shocks received by the weight sensor at four levels. Also, one beep is emitted if a Level 3 shock is received, and two beeps are emitted if a Level 4 shock is received (both of which should be avoided). Shock-Log
While the power is on, up to 50 impacts of Level 3 and Level 4 will be stored in the balance with a timestamp (and log-in user information when the password lock function is used).
*1 This function is especially beneficial for quality managers, as it enables them to check and show how their balances were treated during use.
Cushioning mechanism
The two leaf springs that support the weighing pan mitigate impact shocks significantly

Common accidents in weighing 3: Power failure
Power supply may be interrupted suddenly in the middle of measurement, spoiling your work.
Tare memory
When this function is activated, the tare value is saved in non-volatile memory, and the net value displayed before the power failure occurred is restored once the balance is turned on again. This also allows for the balance to be turned off during weigh-in or loss-in-weight measurement when necessary. Auto power ON/OFF
The weighing mode display is automatically activated when AC power is supplied, so there is no need to press the ON/OFF key as the power comes back on, which is useful when the balance is part of an automated weighing system. Meanwhile, the balance can be set to switch off the display automatically after 10 minutes of inactivity to save power.

Common accidents in weighing 4: Misuse
People may change the balance configuration or sensitivity without permission.
User access control (UAC) and key lock A&D Apollo High Capacity balances can be password-protected in two ways: The first way is to limit use to authorized individuals (up to 11 including one administrator—the administrator can perform all operations while other users are limited to measurements and calibration*2 only) by setting a password for each user. The second way is to set a password for just the administrator, allowing anyone else to use the balance without entering a password, but for measurements and calibration*2 only.
Moreover, upon receiving a command to disable its keys, the balance becomes operable only by sending commands from an external device, such as a PC.
*2 The administrator can inhibit calibration also so that others can perform measurements

Accuracy and precision management
Automatic self calibration (ASC)*3
To ensure accuracy at all times, models with an internal weight (i.e. GX-M series) can be set to calibrate themselves automatically either (1) in response to change in ambient temperature to prevent error due to sensitivity drift, (2) at a set interval time, or (3) at predetermined (up to three) times of the day. Internal calibration can also be performed any time with one key press.
*3 Available for the GX-M series

Automatic precision assessment (APA)
In APA, the balance first makes quick diagnoses on whether there is a critical failure (Dia-Check), and then shows a repeatability test result (Standard Deviation) as well as the minimum weight (QuickMin-S) calculated using an electronically controlled load (ECL).*4 It only takes 1.5 minutes and can be readily included in a daily check SOP.
*4 ECL is A&D's patented technology of generating a minute load (0.3 to 3% of the balance capacity) by purposely altering the equilibrium state of the electromagnetic force restoration sensor.
