Introduction The instrument of this series is a small hand-held 3 1/2 digital multimeter featuring stable, highly reliable and anti-drop performance. It is provided with a LCD display of 15 mm height for clear reading. The circuit design takes LSI double integral A/D converter as its core under the protection of an overload protection circuit, making it a superior and handy instrument.

Safety Information MAS830B, MAS830L, MAS830B and MAS838 Digital Multimeters are designed based on ICE61010 600V(CATII) and pollution degree 2. To ensure the safe and accurate use, please read the instruction manual carefully. Safety Signs Important safety information. Read the manual.
Before measuring any transistor, make sure the probe is not connected to any circuit being measured. Before taking the measurement of voltage with the probe, make sure there is no element connected to the test socket of the transistor. Maintenance ...

Diode and circuit on-off measurement Range Description When the on-resistance is smaller than (70 30)), the built-in buzzer will beep. Display the approximate diode position voltage. Overload Protection: 250V DC or RMS.AC. Temperature measurement Range Test Range Measurement Accuracy 10% Range, 2 digits -20℃...
Notice If you do not know the measured voltage range in advance, set the function/range switch to the maximum range, and then gradually turn to smaller ranges until satisfactory resolution. If the display shows “1”, this indicates an overrange measurement, and the switch should be set to a higher range.
Alternative voltage measurement Place the red probe into the “V.. mA” jack and the black probe into the “COM” jack. Turn the switch to V~ and connect the probe to the power supply or load to be measured. Note: Refer to point 1, 2, 3 and 4 for direct current voltage measurement.
Transistor test Set the rotary switch at “hFE” position. Determine whether the transistor under testing is NPN or PNP and locate the emitter, base and collector leads. Insert the leads into proper holes of the hFE socket on the front panel. Read the approximate hFE value at the test condition of base current 10A and Vce 3V.

The replacement should be of the same specification. The battery for this multimeter is 9V NEDA 1604 or 6F22. The replacement should be of the same specification. Don’t put the instrument into use until the rear cover is screwed after replacing battery or fuse. WARNING To avoid electric shock, make sure the probe are disconnected from the measured circuit before removing the rear cover.
