Velleman's LCD digital panel meter is designed as a digital DC voltage display meter for hobbyists and for industrial applications where accuracy is important. Over range indication informs a user of over-voltage conditions. Two to three readings are taken each second to ensure display reading integrity. For portability, this panel meter operates off of a 9V battery.

    Word of caution, DO NOT hook power up backwards, instant D.O.A. The power supply marking shows a shematic symbol of a battery, the longer dash is the positive. Also the power supply and voltage to be read must be isolated....

    This meter is good for the money. As stated previously, the measured power and source must be isolated or it will be DOA. Be sure to solder the connections. Does anyone know how to set this meter to 0 - 20 volt range? I believe you just need to solder in a resistor across RB and one across RA. Please respond with a comment if so, I'm sure feature buyers would appreciate it too.

    Inexpensive and works well. As received it makes a good voltmeter with an independent 9V battery. It can be used with a common supply if you know what you are doing. It apears to be based on the Maxim ICL7106 or similar. Look up the data sheet and pay special attention to the section on Analog Common which is tied to IN-. It is driven to the +PS minus 2.8V. It can be pulled lower easily but pushing it higher requires >30ma. The inputs have good CMRR but must be kept within the +PS minus 1V to Gnd Plus 1.5V. With a LM324 op-amp and a few resistors you can do almost anything.

  • "resistors needed" by jimreagans on 3/19/2009

    To measure <20 volts, remove resisters RA & RB (it's a jumper). Then use a 10meg resistor for RB and a 100K for RA. Remove the solder bridge at P1 and add a solder bridge at P2. Don't forget the second terminal down is the +9 to 12 volts in... Works great!
