instruction

[1]

Plug the Test Rod cable into the input socket of the unit.

[2]

Select the appropriate level range as required, such as:

Low frequency, 15KHz~60KHz, could set at 0~50mV range;

Mid frequency, 60KHz~250KHz, could set at 0~100mV range;

Hi frequency, 250KHz~3MHz, could set at 0~500mV range.

[3]

Turn on the power.

Put the end of test rod into the water around 3cm. The depth could adjust as needed. The minimum depth is 2cm.

The depth should be recorded for reference. The data should tested and recorded at the same depth to reduce the error for analysis and comparison.

[4]

Check the selected level range is correct. If OK, can start the data reading and recording.

[5]

The scale 0~10 of the alarm set knob are indicated the value 0~100% of the selected Level range.

For example, level range is 0~50mV, alarm set at 25mV, then, the alarm set knob should set at 5.0 position.

Or level range is 0~500mV, alarm set at 300mV, then, the alarm set knob should set at 6.0 position.  And so on.

[6]

If the detected signal level of test rod is lower than the alarm setting, then the alarm be triggered, the green indicator blinks fast and the resistance of the alarm output socket become from open circuit to <3 ohm.

If the alarm set knob set at zero position, this setting is same as switch off the alarm.

[7]

If want to observe the signal waveform or frequency, be connected the signal input socket of oscilloscope with cable to the analog signal output socket that located at the rear panel of the unit. 

If want to record the DC signal, be connected the signal input socket of the DC recorder with cable to the DC signal output socket that located at the rear panel of the unit.

[8]

When switch on the unit without AC power supply, the battery would power on, the green power indicator is on.

When the battery power become low, the green power indicator blinks slowly, reminding recharge.

When switch on the unit with AC power supply, the battery charge, the green power indicator and yellow charging indicator are both on.

Slow charging method is applied in MUE18T to prolong the batteries life. The recharge time is close to using time. So if recharge 8 hours could use 8 hours. The capacity of the installed batteries is 1900mAh, if fully charged could use 18 hours.

After charge or use, please turn off the power.
