Following the instruction, use the device as intended. 3.1. Scale placing • • • The scale should be unpacked outside the hazardous area. Before moving the scale to the place of operation prepare a cable for earthing the device against electrostatic charges.
NOTICE! Mounting the indicator, placing the weighing platform and earthing/zeroing should be performed when the explosive atmosphere cannot appear. Indicators with cable can be mounted on the rack, on the wall or on the table using a special mounting kit. Weighing platform should be placed on even and stable ground far from sources of hit and draughts. It should be also levelled out using the feet. 3.2. Connecting power supplier 1. Place the power supplier outside the hazardous area. 2.

Return to weighing Upon noticing the message press: key – for changes confirmation or key – for resigning. After completion of this procedure the scale returns to weighing. 12. WEIGHING Place a load on a weighing pan. After noticing stability pictogram, , read the weighing result. 12.1.
function pay attention to maximum weighing range, it cannot be exceeded. After removing the load and the package, display shows indication of sum of tarred weights with minus sign. NOTICE: Tarring may not be performed when minus value or zero is displayed. In such a case the display shows message, short sound signal is heard. 12.2. Tarring by inscribing tare value It is possible to inscribe a tare value.
NOTICE: Tarring by inscribing tare value cannot be performed when the tare value has already been implemented into the scale memory. In such a case the display shows message, short sound signal is heard. 12.3. Zeroing In order to zero the indication press zeroing key and . on a display next to symbols: . Zero value is shown The new zero point is treated by the scale as the precise zero. Zeroing is possible while stable status is shown on the display.
12.5. Setting a basic weighing unit The user may set a weighing unit to be active after turning on the scales. Procedure: • Following point 11 of this manual enter submenu, next: • Press key several times to view available units: Selection: A. When the basic unit is set to [kg], users can toggle between: [kg, lb, N]. For verified scales [lb] is not accessible. B. When the basic unit is set to [g], users can toggle between: [g, ct]. For verified scales [lb] is not accessible.
Save changes and return to weighing: See point - 11.2. – return to weighing. NOTICE: Upon activation the scale operates with a set basic unit. 12.6. Temporary weighing unit This function allows users to choose unit for indication. The unit is valid until the scale is switched off or until another unit is chosen. In order to perform the following procedure, operation mode must be accessible, see point 14.1.1 – Enabling operating modes.
13. MAIN PARAMETERS User can adjust the scale to external ambient conditions (setting filters) or individual requirements (autozero, tare value). Respective parameters can be found in parameters group. 13.1. Adjustment of filtering level Procedure: • Following point 11 of this manual enter submenu, next: 1 - 4 - filtering levels to be selected (depending on the ambient conditions) Return to weighing: See point - 11.2. – return to weighing.
13.2. Autozero „AUTOZERO” function has been introduced in order to ensure precise indication. The intended use of this function is automatic control and correction of zero indication. When function is active comparison of results takes place at specified time intervals. If results differ by value smaller than declared AUTOZERO range, e.g. one division, scale is zeroed automatically, stable state is marked – and zero indication – is displayed.
13.3. Tare function operation This function enables the user to set appropriate parameters (depending on needs) for tare function. Procedure: • Following point 11 of this manual enter submenu, next: tArA AtAr - automatic tare function on - stored in scale memory after unplugging it from mains (see point 15.5 for description); tArA no - automatic tare function off (scale tarring by means of T key tArA tArF - ) tare memory function – stores last value of tare in scale memory.
13.4. Median filter The role of the median filter is to eliminate short lasting interference (e.g. mechanical shocks). Procedure: • Following point 11 of this manual enter submenu, next: Fnnd Fnnd no - median filter disabled YES - median filter enabled Return to weighing: See point - 11.2. – return to weighing.
13.5. Determining the minimal load S_Lo parameter works for automatic tare. The rule is that no automatic tare is performed until the indication drops below S_Lo value (gross).
