note! Accuracy specifications consist of two elements:
(% reading) – this is the accuracy of the measurement circuit.
(+ digits) – this is the accuracy of the analog to digital converter.
note! Accuracy is stated at 65°f to 83°f (18°c to 28°c) and less than 75% relative Humidity.
diode test:.............................test current of 1mA maximum, open circuit voltage 2.8V dc typical.
Continuity Check:................... A udible signal will sound if the resistance is less than approximately 30Ω.
Battery test current:..............9V (6mA); 1.5V (100mA).
Input Impedance:................... >1MΩ.
AcV Bandwidth:..................... 45Hz to 450Hz.
dcA Voltage drop:................. 200mV.
display:.................................. 3 ½ digit, 2000 count lcd, 0.5" digits.
overrange indication:............."i" is displayed.
Polarity:..................................Automatic (no indication for positive polarity); minus (-) sign for negative polarity.
measurement rate: ................2 times per second, nominal.
low Battery indication:..........."BAt" is displayed if battery voltage drops below operating voltage.
Battery:.................................. 9 volt (PP9 type).
fuses:.................................... mA, µA ranges; 0.2A/250V fast blow. A range:
operating temperature:.........32°f to 122°f (0°c to 50°c).
storage temperature:.............-4°f to 140°f (-20°c to 60°c).
relative Humidity:..................<70% operating, <80% storage.
operating Altitude:................. 7000ft. (2000m) maximum.
Weight:.................................. 260g.
size:.......................................121.5mm x 60.6mm x 40mm.
safety: for indoor use and in accordance with overvoltage category ii, Pollution degree 2. category ii includes local level,
appliance, portable equipment, etc., with transient overvoltages less than overvoltage category iii.
4. operation
Warning! risk of electrocution. High-voltage circuits, both Ac and dc, are very dangerous and should be measured with great care.
‰
AlWAYs turn the function switch to the "off" position when the meter is not in use.
if "ol" appears in the display during a measurement, the value exceeds the range you have selected. change to a higher range.
note! on some low Ac and dc voltage ranges, with the test leads not connected to a device, the display may show a random reaing.
this is normal and is caused by the high-input sensitivity. the reading will stabilise and give a proper measurement when connected to a
circuit.
4.1.
dc VoltAGe meAsurements
cAution: do not measure dc voltages if a motor on the circuit is being switched on or off. large voltage surges may occur that can
damage the meter.
4.1.1.
set the function switch to the highest V dc position.
4.1.2.
insert the black test lead banana plug into the negative (com) jack. insert the red test lead banana plug into the positive (V) jack.
4.1.3.
touch the black test probe tip to the negative side of the circuit. touch the red test probe tip to the positive side of the circuit.
4.1.4.
read the voltage in the display. reset the function switch to successively lower V dc positions to obtain a higher resolution reading.
the display will indicate the proper decimal point and value. if the polarity is reversed, the display will show (-) minus before the value.
