The comparison function of BVIR works like this: compare the value BVIR gets(the actual value of voltage or resistance, let’s call it VB) and the values set up before(let’s call them VA and VC), if the actual value(VB) is between VA and VC, then green check(√) light will be on, if VB is outside of VA and VC then the red (X) light will be on and beeps.
Step 1: Set up the values for comparison
Press and hold the COMP button up to 3 seconds activate comparison function. When there’s COMP.SET shows up on the right top corner of the screen, it means you can set up the comparison values now, please refer to the following picture.
❶Up-limit of the resistance/voltage; ❷Bottom-limit of the resistance/voltage; ❸Resistance or voltage; ❹Group No., could be up to 10 groups.
Step 2: Set up the up-limit and bottom-limit of resistance/voltage
Use the right arrow button move the cursor to the 1st (thousand) number on the screen, please refer to the following picture, the resistance value could be up to 2000mΩ, you can use up and down arrow to change the values.
And if you want to set up voltage comparison function, the interface should look like following picture, it’s a little different from the resistance setting interface. And the voltage should be between 0 and 25V.
Step 3: Ready to use comparison function
When you set up all the resistance/voltage up-limit and bottom-limit values, press the COMP button again(no need to hold this time, this step is to save the COMP settings). And now you can use the comparison function. If you are in the comparison setting interface and forget to press the COMP button to save the settings, BVIR will go back to the previous interface without saving all your set up after 1 minute. So it’s important to press the COMP button when you finish the settings.
Now you can use the BVIR probes to test the voltage or resistance of batteries, if the voltage/resistance is between in the values you set up, the green check(√) light will be on, if the voltage/resistance is out the value range you set up, the red fault(X) light will be on and the beeper will buzz.
If you set up more than one group values, you can switch to other groups and continue the comparison.
