5.1 Monitoring Data Modes

Press the M (Mode) button repeatedly to cycle through the various measurement displays:

Figure 4: Six measurement modes displayed on the meter.

• Mode 1: Total Time, Cumulative kWh, Total Cost
• Mode 2: Total Time, Current Voltage (V), Current Amperage (A)
• Mode 3: Total Time, Active Power (W), Apparent Power (VA)
• Mode 4: Total Time, Frequency (Hz), Power Factor (PF)
• Mode 5: Total Time, Maximum Power (Max W)
• Mode 6: Total Time, Minimum Power (Min W)

5.2 Setting Alarms (Overload, kWh, Cost)

The meter features multiple protection alarms to alert you when certain thresholds are exceeded.

Figure 5: Visual indication of an active alarm.

1. Press and hold the S button for 3 seconds to enter alarm setting mode.
2. Press M to cycle through Overload (W), KWh Alarm, and Cost Alarm settings.
3. Use + and - buttons to adjust the desired alarm value.
4. Press OK to confirm the digit and move to the next.
5. Once all alarm values are set, press S again to save and exit.

When an alarm threshold is reached, the display will flash "OVERLOAD", "KWh Alarm", or "Cost Alarm", and an LED indicator will blink to warn the user.

5.3 Memory Function

The KTEM02BL IT is equipped with a memory function. All set parameters (like electricity price and alarm thresholds) and cumulative measurement data (kWh, cost, total time) are automatically stored. This means your data will be retained even if the device is unplugged or experiences a power outage.

Figure 6: The meter retains data even when disconnected from power.

5.4 Reset Function

To clear all cumulative measurement data (kWh, cost, total time) while retaining your set parameters (electricity price, alarm thresholds):

• Press and hold the S button for approximately 5 seconds until the display resets.

Alternatively, a small reset button might be present on the device (refer to Figure 1 for exact location if applicable). Use a thin object (like a paperclip) to press it.

6. Maintenance
