3. Software Installation and Connection
Step 1. Find the installation software and open it.
Step 2. You can choose the installation location. Please do not install the C drive. Some systems do not have an installation location and choose the D drive by default.
Step 3. After the installation is complete, open the first run to select the network (when the network firewall is normally turned on). Please be sure to check the public network.
Step 4. Click Connect. Select the device to be connected in the window that appears. After it turns blue, click Connect Device. The IP window that has been set will appear. Just click OK by default.
Notes:
- If it is installed in the C drive, it will cause an error when entering the username and password or adding a work step solution. The solution is to run it as an administrator. If it doesn’t work, please reinstall other disks.
- If the public network is not checked during the first run, it may cause the device to be connected to the status of being connected.
The solution is:
①Turn off the public network firewall.
② Modify the network connection mode of the software. If it cannot be modified, you can reset the firewall default value. Restart the software and check the network connection again.
4. Battery Connection
- Supported batteries: The device supports battery voltages within 5Vandcapacities of any size. Physical specifications support: 18650, 26650 lithium iron phosphate, No. 5 nickel-metal hydride batteries, soft-pack batteries, block batteries, large monomers and other battery connections.
- The minimum height of the probe can be adjusted to 32mm, and the maximum height can be adjusted to 130mm.
- No. 5 AA NiMH battery, 18650 lithium battery, 26650 lithium iron phosphate battery: If you need to adjust the height of the fixture, refer to the scales on both sides to adjust it (cylindrical brackets can be customized separately)
Note:
- After installing the battery, check whether the battery pole piece is in good contact with the probe housing. There will be no current when only the middle needle is in contact with the test.
- 3.7V 240mAH soft pack battery and the 3.2V/10Ah lithium iron phosphate soft pack battery: Install the output line that comes with the battery and connect the battery with the alligator clip or flat clip according to the positive and negative poles.
- To ensure the sampling accuracy, the output line is made with the sampling four-wire connection method. After the alligator clip or flat clip is connected to the battery pole piece, check whether the alligator clip or flat clip on the signal sampling side is in reliable contact.
5. Software Instructions

The cabinet number, device number, and device path number are the basic information of the device.
Software version: the firmware version of the device.
www.heltec-energy.com
Connection mode, IP, port, etc.: indicate the port and IP address of the device andcomputer.
Temperature 1/2: indicates the measurement value of the two temperaturesensors inside the device. When the temperature exceeds 30℃, the fan will automatically run to dissipate heat;
Status: the connection relationship between the device and the computer. Cabinet number: set the cabinet number where the device is located, whichis convenient for the on-site wiring of cabinet-type equipment, and the cabinet sequencenumber can be randomly arranged.
Sampling rate: indicates the frequency of data collection and upload of thedevice.
After selecting list display, the device status is displayed in list format. All operating functions are not affected.

5.3 Step Setting
5.3.1 Data Saving Conditions
1. When you need to save the test data to the computer, please check this item, otherwise the data will not be stored in the computer. There are 3 conditions to choosefrom for storage rules.
2. Time interval: Set the minimum time interval for data saving. After the systemexceeds this time, the software system automatically stores the data in the recordfileof each channel every time. This value should not be set too small, so as to avoid frequent data actions causing the computer to run slowly.
3. Voltage interval: Set the voltage difference condition for data saving. If it is set to 100, it means that when the voltage changes from 3700mv to 3800mv, the systemautomatically stores the data in the channel record file once. If the voltage changes from 3700mv to 3600mv, the storage action can also be triggered. This value shouldnot be set too small, so as to avoid frequent data actions causing the computer torunslowly.
4. Current interval: Set the current difference condition for data saving. If it is set to 100, it means that when the current changes from 500mA to 400mA, the systemautomatically stores the data in the channel record file once. If the current changes from 500mA to 600mA, the storage action can also be triggered. This value shouldnot be set too small to avoid frequent data actions causing the computer to run slowly.
5.3.2 Step Details
Steps can set multiple test step schemes and save vivid names for easy memory, such as “Panasonic 18650 standard test”; click New Step Scheme to add a new scheme; right-click to delete or modify the scheme name. The name will appear in the menu of the operation interface. See the device setting step for details; each step scheme supports the storage and setting of up to 64 steps. Step editing can mix and edit the step execution order. After the step editing is completed, please add a stop step at the end to prepare for the device to stop working to avoid abnormalities.
Add a step: Click Add to add a step; after adding a step, you must set the step supporting execution parameters, otherwise the wrong parameters will cause the risk of damaging the battery.
Modify step: Click the Edit button to reset the parameters in the selected step, or you can directly double-click the step to open it. Delete step: Click the Delete buttonto delete a selected step.
Move step: Click the Up or Down button to move the selected step. Save step: After editing the step, you must click the Save button to save thecurrent step to the software system.

The matching scheme can set a set of qualified standards with multipleconditions. If all conditions are met, they will be checked. For details, see 2.5 QuickMatching Diagram. The configuration conditions support capacity, time, and voltageresults as judgment conditions. Each condition can only fill in one range. It cansupport specifying the result of a certain step as the judgment condition.
For example: The qualified standard of 18650 battery with a nominal value of 2650mA is (see 3.1 Step Setting Diagram for detailed steps): Condition 1: The test capacity of the third step (discharge) of the third cycle reaches 2600~2700mAH; Condition 2: The voltage of the second step of the third cycle (full and static) is between 4180~4200mV, and the two conditions are in an AND relationship.
