Tip of the sensor mounting
Connect the AC Current Sensor (GS DPA-AC, sold separately)
1. Connect the AC Current Sensor (GS-AC**A, sold separately) (1) Recording to the module.
Connecting
: Push the connector in until it locks in.
Disconnecting
: Pull the connector out while pressing down on the lock on the bottom with your finger.
Connector cable
The connector is exclusively used to connect the AC current sensor. Do not connect it directly to

other electrical currents, etc. It will damage the module.
Pulling the AC Current Sensor's cable and holding the sensor by the cable will damage the cable's wires.
Do not pull the AC current sensor cable from the adapter. Press the lock mechanism to unlock the clamps.
2. How to measure with AC Current Sensor
Remove the AC current sensor's lock, insert the measurement cable and push it in until it locks down

Example of measurement Measurement with single-phase 100V, 2 loads When the following connection is established, each current measurement for I, Ia, and Ib is possible. (The clamp in the following figure indicates the measurement point of AC current sensor.) the displayed data does not necessarily follow l = la + lb However, when measured by the GL100, it is not necessarily I = Ia + Ib (Since it is calculated in vector quantity.).

Blondel's theorem: “When the number of electrical conductors is n, the multi-phase power can be measured by the watt-meter (n-1)”. The Δ-connection and Y-connection are described below. The current effective value of R and T power line are measured at the clamp 1 and 2. Using the Blondel's theorem, the GL100 calculates the power with the following formula. Power = ((Measured current (CH1) + Measured current (CH2))÷2) x Set voltage x √3 x Set power factor Measurement method: Measured at the clamp 1 (CH1) and clamp 2 (CH2) in three-phase 3-wire (AC3 3W) mode. The effective current value of R (U) phase is measured at clamp 1 (CH1), and effective current value of T (W) The current effective value of R (U) phase is measured at the clamp 1 (CH1), and the current effective value of T (W) phase is measured at the clamp 2 (CH2). phase is measured at clamp 2 (CH2).
