MAC series ensures fast and precise determination process of water content in a tested sample, and application of a LCD display considerably simplifies functioning, operation and carrying out measurement processes.
Remember that some of tested samples may become dangerous if heated (appearance of poisoning vapours, danger of ignition or explosion). A moisture analyzer MAC series is not intended for dynamic weighing. Even if small amounts of a sample are added to taken off the weighing pan, the mass...
use a moisture analyzer only to determine humidity content in samples and determine mass of a tested sample. Any other use of the moisture analyzer may be dangerous either to the device or the user, before switching on the moisture analyzer, make sure that the nominal power of the device specified on its data plate, is compatible with the supply in the mains to which the moisture analyzer will be plugged in, change of heating element can only be carried out by authorized...
2.7. Staff competence Moisture analyzer MAC series should only be operated and maintained by personnel who is trained and experienced in using this type of instruments. TRANSPORT I STORAGE 3.1. Delivery check Please check the packaging immediately upon delivery and the device during unpacking for any visible signs of external damage.
• Ambient relative humidity should not exceed 80% in the temperature up to 31 ° C, and decrease linearly to 50 % of relative humidity in temperature 40 ° C, • A moisture analyzer should be located on a stable wall console desk or a stable working table which is not affected by vibrations and distant from heat sources, •...
Before plugging to mains, level the moisture analyzer using adjustable feet. Turn the feet in a way that the air bubble of the level is located centrally. 4.4. Standard delivery components • A moisture analyzer MAC series • Insert of drying chamber basis. • Drying chamber shield. •...
Remember to remove the drying pan from the drying chamber before its cleaning. If the drying pan assembly is installed while cleaning it may damage instrument’s measuring system, thus remove it from the bracket. 4.6. Plugging to mains A moisture analyzer can be plugged to mains only by means of original power cord, which comes standard with the moisture analyzer.

WEIGHING Before start of measuring process or in case of essential change of ambient conditions at a workstation (e.g. ambient temperature change at a workstation) the moisture analyzer requires adjusting. The procedure of moisture analyzer adjustment is described further in this user manual. •...
User of a moisture analyzer can adjust its operation to current ambient conditions at a workstation (by changing the value of digital filters), or according to user needs (autozero operation or display backlight) by using parameters grouped in this function. 9.1.
CAUTION: The stronger filtering setting the longer weighing time. 9.2. Autozero function In order to ensure moisture analyzer’s precise mass indication, autozero (Auto) software parameter has been introduced. The application of this function is automatic control and correction of zero indication. When function is enabled, it compares moisture analyzer indications at declared time interval e.g.
9.3. Access to library of drying programs In order to use the library of drying programs set parameter <Libr> to value <YES>: - libraries of drying programs disabled, - libraries of drying programs enabled.
9.4. Backlight of measurement result (display backlight) The function enables switching on and off backlight of measurement result on the display. - backlight disabled - backlight enabled - backlight disabled automatically if measured indication does not change within 10 seconds. CAUTION Moisture analyzer software has implemented option of automatic backlight switch off bl = Aut.

10. MOISTURE ANALYZER ADJUSTMENT As the gravitational acceleration force has different value at various latitudes and altitudes, a moisture analyzer should be adjusted to present working conditions. This process should take place at the first installation of the instrument on site and at its every re-location –...
10.1. External adjustment External adjustment in moisture analyzer MAC series should be carried out with an external mass standard / weight class F2 or higher. Start of external adjustment process, On selecting CAL mode, the moisture analyzer displays a command unLoAd –...
10.2. Adjustment test Adjustment test is a comparison of mass of an adjustment weight with the value of last adjustment saved in moisture analyzer’s memory. This process is automatic and its result is previewed on the display (if a moisture analyzer is connected to a computer or a printer through RS 232 interface, data on adjustment test is printout –...
10.3. Drying chamber adjustment Drying chamber adjustment is a process aimed at adjusting the temperature sensor of a moisture analyzer. To carry out temperature adjustment of a moisture analyzer place a control thermometer in an opening of the drying chamber, as shown on below picture.
Page 29
Go to menu P1-03 tE_CAL, adjustment process is initiated automatically. The moisture analyzer displays current temperature in the drying chamber. After 8 minutes the display indicates (pulsating) temperature value. Use navigating keys (up and down arrow) on moisture analyzer’s overlay to set temperature value to be equal to the current temperature displayed on the control thermometer.
to the current temperature displayed on the control thermometer – as in previous step. On entering the temperature value and accepting it by pressing Print/Enter key, the software starts the last part of temperature adjustment process. The moisture analyzer heats the drying chamber to another temperature value, which is maintained for 8 minutes.
Remember, that if the parameter is set to YES, then a report is generated and sent (printed) automatically. Content of report from adjustment process depends on the settings of GLP parameters. Any option in the GLP submenu which attribute is YES is included in a report from adjustment process.
