Page 11: Set Liquid Type
SET LIQUID TYPE - After entering the Gen Set Menu - Select “SET LIQUID TYPE” - Press “Enter” Select the option “WATER or AS PER SET SG” by pressing keys “A” or “B”, press “Enter” to confirm. Importance of AS PER SET SG: In cases where liquid in use is not Water you can enter the SG of this liquid in the “Configuration Menu”... -
Page 12: Lead Zero Blank
LEAD ZERO BLANK Importance: This option is mainly for users who want the reading up to 3 digits before the decimal point. E.g. Reading for the sample is 3gms a) If Lead Zero Blank is “Disabled” then the reading would be displayed as 003.00g b) If Lead Zero Blank is “Enabled”... -
Page 13: Key Beep Set
KEY BEEP SET Importance: For a buzzer sound of every click the user makes, this ensures the confirmation of that click. However the user can also switch it this sound off in case not required. - After entering the Gen Set Menu - Select “KEY BEEP SET”... -
Page 14: Auto Power Off
AUTO POWER OFF Importance: This is a power saving option. On enabling Auto Power Off the equipment switches off automatically if it remains un-operated for 30mins. - After entering the Gen Set Menu - Select “AUTO POWER OFF” - Press “Enter” - Select “DISABLE or ENABLE”... -
Page 15: Print Baud Rate
PRINT BAUD RATE Importance: For operating the Printer the user needs to configure the Densimeter with a Baud rate required for Printer operation. - After entering the Gen Set Menu - Select “PRINTING MODE” - Press “Enter” - Select out of the following options: (9600 / 19200) The options can be viewed by pressing the key “A”... -
Page 16: Set Time & Date
SET TIME & DATE Importance: This option can be used to set the Date and time of operation which in the Idle mode can also be used as a Digital Table Clock. - After entering the Gen Set Menu - Select “SET TIME & DATE” - Press “Enter”... -
Page 17: Calibration
Calibration Step 1 Step 2 Step 3 Calibration is the most important procedure required for finding the % accuracy of the results, especially if the equipment is moved or shifted. Hence to ensure accuracy this step should be performed. The steps for the calibration are as follows: From the Idle Mode press A + Enter (for 3 seconds) key till you enter into the Calibration mode. -
Page 18: Comparator Set
2. Comparator Set: Importance: This function enables to the user to set limits for the readings of that particular batch of samples. Once he enters the upper and the lower limits, a range has been defined for the reading, if this crosses the upper side then there will be and indication of “HI”... -
Page 19: Liquid Sg Set Mode
4. Liquid SG Set Mode: Importance: If the liquid used during testing is other than Water then you can set the specific gravity of the liquid in use with this option. The Density for sample under test is calculated accordingly. In this you can set the SG of the liquid in use. -
Page 20: To Measure Density
To Measure Density: 1. Solid Mode: Assumed that all the mechanical arrangements are with respect to solid mode you can start the measurement by following the below steps: Step 1 Step 2 (a) Step 2(b) Step 3 Step 4 Step 5 Step 6 (a) Step 6 (b) Step 9... -
Page 21: Liquid Mode
2. Liquid Mode Measurement: The Dak Densimeter also has the provision for Liquid density measurement. To measure the liquid density, an optional Liquid Density Kit would be required. This machine calculates density of a liquid sample by comparing the weight of a Standard Glass Sample in water with its weight in liquid test sample. - Page 22 Measuring the density of liquid. Assumed that all mechanical arrangements are with respect to the liquid mode: 1. Select LIQUID MODE by keeping the A Key pressed while pressing B along with “A” till you reach the required mode 2. Place the GLASS REFERENCE in the sample liquid and press OK. 3.

Page 23: How To Compensate Liquid Sample Temperature
HOW TO COMPENSATE LIQUID SAMPLE TEMPERATURE PREPARATION 4 - If the temperature compensation is necessary, follow the procedure below to change the compensated liquid temperature and the compensating temperature rate of liquid sample. What is "the compensating temperature rate"- The changing number of the density when the liquid is raised by1 degree centigrade. -
Page 24: Steps Of Measurement
STEP OF MEASUREMENT 1 Make sure the display is 0.00g. 2. Pour about 50cc. of liquid sample in a Beaker. 3. Put the Standard Glass Sample used for memorizing data into the Beaker at the preparation 4. Set the Beaker prepared at Step 2. Correctly on the Beaker Line of Beaker Stage 5. -
Page 25: Special Measurement Cases
CAUTION FOR LIQUID DENSITY MEASUREMENT: 1) Do not use the liquid sample as to erode the machine body or spare parts. 2) Do not spill liquid sample on the machine body or spare parts. 3) Open the Airtight Wind Shield when measuring highly volatile liquid. Fullness of the gas may cause the machine defect. - Page 26 Step 1 Step 3(a) Step 3 (b) Step 4 1. From display 0.00g, sink one Petri dish on the Measuring Tray in water, and put the other Petri dish onto the lid of Sensor like in the aerial mode of measurement. - The weight will be displayed.
