The VDIV2:1 uses precision resistor networks to bring sensors with high output voltages into your datalogger’s common mode range, allowing your datalogger to measure the sensor. The VDIV2:1 divides the sensor’s signal voltage by a factor of two.Read More
The VDIV2:1 contains two 10 kΩ resistors that have a ratio tolerance of ±0.02%. Increased input settling time may be necessary to accommodate the relatively high resistance of the voltage divider.
|Resistors||10 kΩ and 10 kΩ|
|Ratio Tolerance||±0.02% (@ 25°C)|
|Power Rating per Element||0.1 W (@ 70°C)|
|Maximum Ratio Temperature Coefficient||2 ppm/°C (0° to 70°C)|
|Dimensions||1.5 x 1.5 x 2.7 cm (0.6 x 0.6 x 1.0 in.) for body with prongs|
|Weight||6 g (0.2 oz)|
The VDIV2:1 uses two adjacent single-ended analog inputs (one differential channel); an adjacent analog ground channel accepts the "ground prong" of the VDIV2:1. Not all datalogger terminal strips have this sequence on all channels, so please check your datalogger's wiring panel to confirm channel assignments, especially if you plan to use multiple terminal input modules.
Please note that if a CR10X will be used to measure thermocouples in the same application, newer CR10X Wiring Panels and the CR10XTCR Reference Thermistor (with its accompanying thermocouple cover) are deep enough to cover the datalogger input channels with a VDIV2:1 attached; older CR10TCRs are not deep enough.
The VDIV2:1 is measured with either the VoltSE or VoltDiff Instruction in CRBasic, and with Instruction 1 (SE Volts) or 2 (DiffVolts) in Edlog. Each VDIV2:1 can be wired to make one differential measurement or two single-ended measurements.

‡Compatible CR9000(X) modules are the CR9050 and the CR9052; the CR9051 is partially compatible.
#As shipped, the prongs on the VDIV2:1 are too short to fit the CR7. If you're determined to use the VDIV2:1 with a CR7, you can solder wire to the prongs, thereby extending their length.

These two voltage dividers can handle different maximum input voltages.
The CR1000 can measure analog voltages in the ±5 Vdc range. A voltage divider such as the VDIV2:1 is required to reduce 10 Vdc to an acceptable range. For examples of wiring and programs, see the VDIV10:1/VDIV2:1 manual.
