6.1. Display and Symbols Display and Symbols Description Stability mark When the current weight value is stable, this mark is displayed. It means a proper condition that this value is readable. Zero point mark When the key is pressed with nothing on the pan, ZERO this mark is displayed.
Page 22
Display and Symbols Description Counting mode (Example) This mode uses the stored unit mass and counts the number of articles on the pan. The unit is Storing the unit mass for the counting mode (Example) The unit mass is stored, using 20 pieces of samples. The zero value means that no articles are on the pan.
isplay and Symbols Description Calibration error The calibration mass is too heavy. Check the base unit and the weighing pan. Does not display zero when the scale is turned on. Remove anything that is on the weighing pan. Perform zero point calibration. The weight value is unstable due to drift or vibration when the scale is turned on.
Page 24
Function table: used to select a parameter. Display and Symbols Description SET key, key Normal weighing mode: used to turn the comparator on or off. (Refer to f6 ) Counting mode: used to enter the mode to store the unit mass.
7. Basic Operation 7.1. Turning the Scale on/off and Weighing 7.1.1. Type V or Type L with AC Adapter Step 1 Ground the scale. Step 2 Confirm that nothing is placed on the pan. Step 3 Confirm that local voltage and receptacle type are correct. Step 4 The scale turns on/off using the key alternately.
7.1.2. Type L with Batteries Step 1 Install six new batteries. Refer to "5.2. Installing the Batteries for Type L". Step 2 Confirm that nothing is placed on the pan. Step 3 The scale turns on/off using the key alternately. ON/OFF Step 4 Check the accuracy of weighing.
7.2. Tare (And Net Display) The "tare" is used to cancel the mass of a container, which is placed on the pan to contain the article to be weighed. Caution The tare reduces the weighing range. The current tare value is reset by pressing the key or turning the scale ZERO off.
7.3. Weighing Range for the HV-G Series This is the function to select a weighing range for the HV-G series. The mass value is displayed within a selected range. Select automatic range (f2 0) or manual range (f2 1) in the function table. Operation and Performance Function table Description...
7.4. Mode Key (Changing Unit and Mode) Pressing the key changes the display as follows. Refer to function table f3 for MODE units. Usable units are according to the factory settings. If the law in your area Pound permits, you may use all of the units.
Page 30
Description The status of "Inactive comparator ( )" is that comparator function ( f6 0 f6 2 f6 4 ) is selected and this comparator is not used. The comparator can be selected to f6 6 be ON or OFF using the SET key alternately. The following parameters are stored in the same memory.
8. Counting Mode The counting mode is the function to convert the total mass value (total weight) of articles to a count, when each article has the same mass value. To use this function, store a unit mass in advance. Even if the AC adapter or the batteries is removed, the unit mass is maintained in non-volatile memory.
8.2. Counting the Number of Articles Step 1 Press the key to display the unit MODE Step 2 Store the unit mass of the article. Refer to "8.1. Storing a Unit Mass" Step 3 Place the container on the pan. Press the key.
9. Percentage Mode The percentage mode is the function to display a mass value in the unit of "%". To use this function , store a 100% mass value in advance. The 100% mass value is stored in the scale even if the power is removed. 9.1.
9.2. Reading the Percentage Step 1 Press the key to display the unit %. MODE % Percentage mode Step 2 Store the 100% mass of the article. Storing a 100% mass Refer to "9.1. Storing a 100% Mass " A container(bowl) Step 3 Place the container on the pan.
10. Accumulation Function This function counts the number of times articles are weighed, calculates the total mass value and can display the number (accumulation count) and accumulated mass value. The accumulation function is displayed with up to 6 digits. The balance can not display 7 or more digits, therefore the leading digits are not displayed.
Function table Description When the display is a positive stable value and not nearly-zero, the scale accumulates the data automatically. The next accumulation f8 3 can be performed after the display becomes nearly-zero or a negative value. When the display is a stable value and not nearly-zero, the scale accumulates the data automatically.
10.2. Operation and Performance (Examples) Example 1 In this example, the scale accumulates the value each time an article is weighed. The function parameter is set to f8 3 . Step 1 Press the key to display MODE Step 2 Press the key to reset the accumulation data.
11. Upper/Lower Comparator Function This function compares a weight value with the upper limit (HI) and the lower limit (LO) and displays the results. To use this function, set the "Comparator function ( )" parameters in the f6 0 f6 7 function table, upper limit value (HI) and lower limit value (LO).
Function table Description When the weight value becomes stable and not nearly-zero, the f6 7 scale compares the value. It does not compare on an unstable condition. Caution The upper limit value (HI) must be greater than the lower limit value (LO). The parameters of the upper limit value (HI) and the final value (HI) use the same memory.
Page 40
Step 5 If either of has been f6 0 f6 2 f6 4 f6 6 selected, press the key to use the comparator. Step 6 Press the key to display the blinking HI. MODE Step 7 Set the upper limit value using the following keys. Selecting the figure to be changed.
11.2. Operation and Performance (Examples) Example 1 This example is set as follows: Function table (The scale always compares the weight value f6 1 even when the value is nearly-zero.) Upper limit value (HI) 7.000 kg Lower limit value (LO) 6.500 kg Case The comparison starts when the scale is turned on.
12. Full/Dribble Batch Function This function changes the scale to a filling machine which sub-divides a bulk product ( like grain) into loads of predetermined and virtually constant mass. To use this function, set the parameter of the "Comparator function ( )", f6 9 "...
Page 43
Caution The comparison of the full/dribble batch function can not be restored. (One way sequence). If the weight value becomes less than the final value after the value reached a predetermined target value, neither HI nor LO is on. The parameters of the upper limit value (HI) and the final value (HI) use the same memory.
12.1. Preparation (Setting Parameters) Step 1 Turn off the display. Press and hold the key and press the key. ZERO ON/OFF The function table is displayed. Step 2 Press the key to display an item of the ENTER comparator function ( Step 3 Select a parameter of the full/dribble batch function ) with the key.
Page 45
Step 8 Press the key to display the blinking HI (of the MODE final value). Step 9 Set the final value using the following keys. Selecting the figure to be changed. < Changing the number of the figure. ∧ Step 10 Press the key to store the new parameter and ENTER display the blinking OK (of preliminary value).
13. Simple Batch Function This function compares a weight value with the final value, preliminary value and zero band for the full/dribble batch function. The result is indicated by zero band (LO indicator), full flow (HI indicator) and dribble flow (OK indicator). Even if the weight value is increasing or decreasing, this function can compare it.
Caution The parameters of the upper limit value (HI) and a final value (HI) use the same memory. The parameters of the lower limit value (LO) and the preliminary value (OK) use the same memory. The upper/lower comparator function, the simple batch function and the full/dribble batch function can not be used at the same time because these parameters use the common memory.
Step 6 Press the key to display the blinking HI (of the MODE final value). Step 7 Set the final value using the following keys. Selecting the figure to be changed. < Changing the number of the figure. ∧ Step 8 Press the key to store the new parameter and ENTER display the blinking OK (of preliminary value).
14. Calibration (Adjusting the Scale) The scale is an instrument which weighs the "weight" and displays its "mass". Calibration is the adjustment function so that the scale can weigh correctly. Three steps of calibration are available Gravity Acceleration Correction ... The function to correct the scale’s local gravity acceleration, so that the scale functions correctly when the calibrated scale has been moved to a distant place.
