|
To measure current, the VM-1 basic meter is ordered with the current input back board as # M700. Not included is the appropriate current shunt. Refer to the price list for shunts. The back board has screw terminals and a power supply that isolates the VM-1 from the power supply. Back board has isolated 12VDC meter supply in order to read shunt currents that are significantly above ground potential. |
|
To measure AC Volts, the VM-1 basic meter is ordered with the AC rms converter back board as #M710. The back board has screw terminals and a power supply that isolates the VM-1 from the power supply. The back board has screw terminals and a power supply that isolates the VM-1 from the power supply. Back board has isolated 12VDC meter supply in order to AC voltages that are significantly above ground potential. |
|
To measure AC Amps, the VM-1 basic meter is ordered with the AC rms converter back board as # M720. The back board has screw terminals but does not need the isolator power supply since the current transformer used for sensing isolates the VM-1 unless the current shunt is used.* Built-in current shunt 10 ohm load for 1000:1 current xfmrs. |
|
To measure AC hertz or frequency, order the VM-1 basic meter with the AC hertz converter back board. The back board has screw terminals and a power supply that isolates the VM-1 from the power supply. Back board has isolated 12VDC meter supply in order to AC voltages that are significantly above ground potential. Reads up to 500hz. Ideal for measuring woofer frequencies or AC power generation. Must specify AC voltage range. |
