This document describes the Elmeasure SL VDC | SL ADC | μA VDC | μA ADC series of meters, designed for measuring and displaying various electrical parameters.

Function Description

The Elmeasure SL VDC | SL ADC | μA VDC | μA ADC meters are versatile instruments used for monitoring direct current (DC) voltage and current, as well as micro-ampere (μA) voltage and current. These meters are designed to provide accurate readings for critical electrical parameters in various applications. They feature a 1-row, 4-digit display for clear indication of measured values. The meters support universal auxiliary supply, making them adaptable to a wide range of power environments. A key feature is the auto-scaling of the kilo decimal point, which simplifies reading and interpretation of large values. The devices also include a user-configurable (editable) password for security and to prevent unauthorized changes to settings.

Usage Features

Display and Key Indication:

The display shows the measured value, with "MINUS" indicating negative values and "Kilo" indicating auto-scaled kilo decimal points.
Navigation keys allow users to view parameters upwards or downwards and to access communication settings.

Programming Mode:

Entering Setup Mode: Press Up + Down keys simultaneously.
Password Entry: Enter the password (default 1000). A blinking digit indicates that editing is possible.
Editing Values:
- Press Down to decrement a value (from 9 to 1).
- Press Up to move to the next digit (up to the 4th digit).
Viewing and Editing Parameters:
- Press Down to view parameters.
- Press Up to edit a selected parameter.
- Press Down to decrement values or select from available options.
- Press Up to save the value/parameter.
Saving Changes: After editing all parameters, the screen will prompt "S8UE" (Save). The display will show "Y" (YES). Press Down to change to "n" (NO) if you don't want to save. Press Up to save the changes.

Safety Precautions (Caution):

Hazardous voltages are present at the rear terminals during normal operation.
Installation, disconnection, or removal must be performed by qualified, trained personnel after de-energizing the connected circuit.
The warranty will be void if the seal is broken, or due to improper installation or grounding.

Maintenance Features

Troubleshooting Guide:

Meter display does not turn ON:
- Check if power supply is applied to AUX terminals.
- Verify fuse connection (use specified ratings).
Data displayed / reading incorrect:
- Confirm that CT/PT ratios are set correctly.
- Check if the proper configuration mode (Star/Delta/1Phase) is correctly set.
RS485 communication does not work:
- Ensure baud rate and parity settings match between the meter and connected computers.
- Verify memory mapping in the software.
- Check if the device ID of the meter is unique and properly maintained.
- Confirm that the converter is working correctly.
