Current input: Measure current by connecting an appropriate shunt resistance (e.g., optional B-551 250Ω for 4-20mA on a 1-5V range) across the + and – terminals.

Logic / pulse input: Connect signals to terminals 1-4 (+) and the G (Ground) terminal. Use the designated push-release connectors.

Note: The GS-4VT module is not dustproof or waterproof. Use it in a proper environment.

To avoid damage, do not exceed these limits:

Voltage/Thermocouple Inputs:

Between Input terminal (+) and Input terminal (-): DC60Vp-p

Between Input terminal (-) and Input terminal (-): 60Vp-p (Note: PDF states this redundancy, likely meant between different channels’ negative terminals)

Between Input terminal (-) and GND terminal (G): DC60Vp-p

Withstand voltage (Input terminal (-) to GND): 350Vp-p/1min.

Logic/Pulse Input:

Between Input terminal (+) (1-4) and GND terminal (G): DC24V

If input exceeds 110% of the selected measurement range’s full scale, “+++++” (positive over-range) or “—–” (negative over-range) will be displayed.

Yes, please note the following:

Do not block the air vents of the GL100 main unit. Keep at least 20 cm clear space around it.

Allow the unit to warm up for 30 minutes or more after power-on for stable temperature measurements.

Rapid temperature changes at the input terminals can cause measurement errors.

In noisy environments, connect the GND terminal (G) to ground to improve stability.

The GS-4TSR terminal supports:

Thermistor input: Connect optional GS thermistor sensors (GS-103AT-4P or GS-103JT-4P) to the +/- terminals.

Logic / pulse input: Connect signals to terminals 1-4 (+) and the G (Ground) terminal using the push-release connectors.

WARNING: This terminal is for thermistor input only. Do not input voltage or electric current, as this can cause damage.

Note: The GS-4TSR module is not waterproof or dustproof. Use it in a proper environment. G is the GND terminal for this module.

1. Connect the GS-DPA-AC adapter module to the GL100 main unit.

2. Connect the optional AC Current Sensor (GS-AC**A, sold separately) to the input terminal on the GS-DPA-AC adapter by pushing the sensor’s connector in until it locks.

3. To disconnect the sensor, press down on the lock on the bottom of the connector and pull it out.

4. WARNING: This connector is exclusively for the specified AC Current Sensor. Do not connect voltages or other currents; it will damage the module.

5. CAUTION: Do not pull the AC Current Sensor’s cable or hold the sensor by its cable, as this can damage the wires.

6. To measure, unlatch the AC Current Sensor clamp, place it around the measurement cable (ensure correct orientation: K side towards power source, L side towards load), and push the clamp closed until it clicks.

7. Configure the measurement mode (AC1Φ2W, AC1Φ3W, AC3Φ3W), sensor type (50A, 100A, 200A), measurement voltage (effective voltage, 90-264V), and power factor (0.30-1.00) in the GL100’s AMP settings screen.

The GL100 measures the current using the AC sensor and calculates the power value based on the user-set voltage and power factor settings in the AMP menu. The formulas used internally are:

AC1Φ2W (Single-phase 2-wire): Power = Measured current x Voltage x Power factor (2ch measurement possible)

AC1Φ3W (Single-phase 3-wire): Power = (Measured current (ch1) + Measured current (ch2)) x Voltage x Power factor

AC3Φ3W (Three-phase 3-wire): Power = ((Measured current (ch1) + Measured current (ch2)) ÷ 2) x Voltage x √3 x Power factor

During free-running, only instantaneous power (kW) is displayed. During recording, you can toggle between instantaneous power (kW) and accumulated power (kWh) using the ◀ and ▶ keys. To clear the accumulated value, stop recording and start a new recording; the accumulated value resets at the start of recording (including during trigger waiting state).

When measuring ultraviolet rays that can harm eyes or skin, wear protective glasses, apply light shielding, etc.

If the sensor unit becomes dirty, wipe it with a soft cloth, as dirt can affect measurements.

Handle the sensor unit carefully to avoid cracking. A cracked sensor may affect measurements and should be replaced if damaged.

Power must be supplied via the USB cable; battery operation is not supported when using the GS-CO2 sensor.

Do not use the module close to your face, as your breath (CO2) can affect measurements.

Ensure the module’s aperture (vent holes) is not blocked, as this can affect airflow and measurements.

The sensor has an internal lamp that flashes every two seconds for detection.

Attaching just the sensor module to a wall can damage the connector cable; always connect it to the GL100 main unit (or extension cable).

The sensor measures humidity based on changes in capacitance due to moisture absorption. Dust, fumes, and organic compounds can affect measurements. Use in environments with large quantities of these substances may cause large deviations.

The sensor can be mounted using the hook portion.

The GS-DPA module itself has no water protection, even though the GL100 main unit has basic protection. Be careful during installation and handling.

Always connect all desired sensors (GS-LXUV, GS-CO2, GS-TH only) to the branch adapter’s left and right sensor connectors *before* connecting the branch adapter to the GL100.

When using the CO2 sensor (GS-CO2) in combination with another sensor via the GS-DPA, you *must* use a USB cable connection for power; battery power is insufficient.

Only connect GS-LXUV, GS-CO2, or GS-TH sensors to the GS-DPA’s sensor connectors. Connecting other devices may damage the GL100 or the adapter.

You cannot connect two sensors of the same type (e.g., two GS-TH sensors) to the GS-DPA at the same time.

The following combinations are possible using the GS-DPA (sensors sold separately):

1. Illumination / Ultraviolet sensor (GS-LXUV) + Temperature and humidity sensor (GS-TH)

2. CO2 sensor (GS-CO2) + Temperature and humidity sensor (GS-TH) (*Requires USB power*)

3. CO2 sensor (GS-CO2) + Illumination / ultraviolet sensor (GS-LXUV) (*Requires USB power*)

You cannot connect two identical sensors simultaneously.

During recording with combined sensors, the instantaneous values for both sensors are displayed. You can use the ◀ and ▶ keys to cycle through the available accumulated value screens for the connected sensors.

Example (LXUV + TH): Pressing once shows accumulated Temperature (°Ch) and Dew Point (°C). Pressing again shows accumulated Illumination (klxh) and accumulated UV-A (mWh/cm²).

Example (CO2 + TH): Pressing once shows accumulated Temperature (°Ch) and Dew Point (°C). (CO2 does not have an accumulated display).

Example (CO2 + LXUV): Pressing once shows accumulated Illumination (klxh) and accumulated UV-A (mWh/cm²). (CO2 does not have an accumulated display).

All accumulated values are cleared automatically when you start a new recording (including during trigger waiting state).
