600uA Automatic Digital Multimeter

600V AC (RMS) or 600V DC Temperature And Humidity Meter

 
 Buzzer

When the key is pressed or the function switch is on, the buzzer will sound "Beep" (about 0.25 seconds). If the measured voltage or current is greater than the set alarm value, for example, the AC voltage is greater than 600V, The voltage is greater than 600V, AC and DC current greater than 10A, the buzzer will continue to pronounce, as over-range warning; automatically shut down about 1 minute before the buzzer will be issued five consecutive warning, before the shutdown buzzer will send a long warning ; When the automatic shutdown function is canceled, every 15 minutes will be issued 5 consecutive warning.

Automatic shutdown

1) If there is no operation for any 15 minutes after power on, the instrument will go to sleep automatically to save power. 1 minute before the shutdown, the buzzer has 5 prompts, shut down before a long sound into the dormant state. (Note: automatic shutdown is still 3 ~ 5uA of the working current, a long time do not use the best to go to OFF or unplug the battery)

2) automatically shut down, press the FUNC key, the instrument to resume working status. Or turn the knob switch to OFF, and then rotate to the desired range.

3) If the "FUNC" key is pressed while the unit is turned on, the auto power off function is canceled. 13

 
 
Technical indicators
 
Ambient temperature: 23 ± 5 ℃ Relative humidity: <75%
3.2.1 True rms zero input
3.2.1.1 The measurement of sine wave signal, the use of true RMS measurement method than the traditional average response method error is small.
3.2.1.2 True RMS The instrument can accurately measure the sine wave signal, but if it is on the AC function, the instrument may display 1 to 50 if the measured signal is not input (shorted at the AC voltage range and the input terminal) Word between a reading. These deviations are normal. Within the specified measuring range, they do not affect the accuracy of the multimeter to measure alternating current.
3.2.1.3 True RMS requires that the input signal reach a certain level for measurement. Therefore, the AC voltage and current range is specified between 2% and 100% of full scale.
 
 
 
3.2.2 DC voltage

- Input impedance: 10MΩ
- Maximum input voltage: 600V DC or 600V AC (rms)
Note:
In the small voltage range, the pen is not connected to the circuit under test, the instrument may have beating the reading,
This is normal, this is because the instrument caused by high sensitivity, does not affect the actual measurement results.
 
 
3.2.3 AC voltage
 

- Input impedance: 10MΩ

- Maximum input voltage: 600V AC (RMS) or 600V DC

- Frequency range: 40 ~ 1000Hz True RMS

Note:
In the small voltage range, the pen is not connected to the circuit under test, the instrument may have beating the reading,
This is normal, this is because the instrument caused by high sensitivity, does not affect the actual measurement results.
 
 
 
3.2.4 Alternating current
 

- Overload protection: mA range fuse (self-recovery fuse 200mA / 250V)
10A range without insurance
