Frequently Asked Questions - 2115-1 Daytronic
How do I connect a load cell to the 2115-1?
Connect the sensor wires to the input terminals on the rear panel. Ensure the excitation leads are connected to E+ and E-, and the signal leads to S+ and S-. Use shielded cable for best noise immunity. Check the wiring diagram in the manual.
What is the recommended warm-up time before taking measurements?
Allow the instrument to warm up for 30 minutes after powering on to achieve specified accuracy. For critical measurements, a 1-hour warm-up is recommended.
How do I perform a calibration?
Apply a known reference signal or shunt calibration resistor. Use the front panel zero and span buttons to adjust the display to the correct value. The device supports digital scaling for direct engineering unit readouts.
Can the 2115-1 measure both bridge and DC voltage signals?
Yes, the input can be configured for strain gauge bridge or ±5 VDC analog signals via internal jumpers. Consult the manual for configuration details.
What is the maximum input voltage?
The analog input is protected for ±30 VDC without damage. The normal operating range is ±5 VDC.
How do I set the digital filter?
Press the filter key and use the arrow buttons to adjust the time constant from 0.1 to 10 seconds. Higher values provide more stable readings.
Is the 2115-1 panel mountable? What is the cutout size?
Yes, it is designed for 1/4 DIN panel mounting. The recommended cutout is 92 x 92 mm. Secure the instrument with the provided mounting clamps.
Does the device support RS-232 communication?
An optional RS-232/RS-485 interface card can be installed. It allows data logging and remote configuration. The default baud rate is 9600 bps.
What power supply options are available?
The standard model operates on 100-240 VAC, 50/60 Hz. An optional 12-24 VDC power supply version is available for industrial installations.
How should I clean and maintain the 2115-1?
Clean the front panel with a soft, damp cloth and mild detergent. Do not use abrasive solvents. Periodically check calibration and connections. Replace the fuse with the same rating as indicated on the rear panel.
