Page 2: Package Contents
INTRODUCTION The Mooshim Mooshimeter BLE-DMM-2X-01A (hereafter “The Meter”) is a battery powered multimeter capable of handheld and remote usage via Bluetooth Low Energy. This manual details how to safely use your Mooshimeter. The Meter meets CAT III IEC 61010-1 3 edition and 61010-2-030 standards.
Page 3: Safety Information
SAFETY INFORMATION WARNING Denotes a potentially hazardous situation that may result in injury or death CAUTION Denotes a potentially hazardous situation that may result in damage to the meter NOTE Denotes a situation that may result in degraded or incorrect measurement ...

Page 5: Measuring Voltage
BASIC MEASUREMENT INSTRUCTIONS MEASURING VOLTAGE WARNING Risk of Electrocution. For determining whether a circuit is “live” exercise caution if the meter does not report a voltage. This may indicate a poor connection to the circuit being tested. Make sure the probe tips are fully in contact with the circuit before assuming the circuit is safe.
Page 6 MEASURING CURRENT WITH INTERNAL CURRENT SHUNT WARNING Exercise care when connecting in series with a circuit, especially those containing motor(s). Sudden disconnects may create higher than expected voltages due to inductive kick. WARNING Perform a Fuse Check before measuring currents with the internal current shunt.
Page 7 MEASURING CURRENT WITH AN EXTERNAL CURRENT SHUNT WARNING This measurement mode is capable of measuring currents many orders of magnitude larger than is typically possible with a handheld meter. Exercise caution while interfacing to high ampacity circuits. NOTE The accuracy of this measurement mode depends on the accuracy of the external current shunt used.
Page 8: Measuring Resistance
MEASURING RESISTANCE NOTE Do not measure resistance on a live circuit. Doing so will result in incorrect readings and may engage the internal protection circuitry. Should this occur, wait 5 minutes before taking further measurements. Resistance is measured between the Ω and C terminals. Polarization is not important.
Page 9: Diode Testing
DIODE TESTING NOTE Do not use the diode test functionality while connected to a live circuit. Doing so will result in incorrect readings and may engage the internal protection circuitry. Should this occur, wait 5 minutes before taking further measurements. To test diodes or other silicon junction devices, a test current is pushed through the device under test and the resulting voltage is measured.
Page 10 USING A BNC ADAPTER The 4 terminals are arranged with 0.75” spacing to allow for use of a standard BNC adapter. Measurements using the A or Ω terminals can be used with the C terminal as usual. To use a BNC adapter with the “V” input, use the “A” terminal as the common input.
Page 11: Two Channel Measurements
TWO CHANNEL MEASUREMENTS Your Mooshimeter is capable of reading any two of its three channels simultaneously. NOTE Measurements using the internal current shunt will experience a degree of cross-talk due to the impedence of the Common lead. Other measurement types will also experience this cross-talk, but it should be negligible. MEASURING SMALL RESISTANCES / CALIBRATING A CURRENT SHUNT The Mooshimeter can be used to measure small resistances in a live circuit.
Page 12: Power Factor
POWER FACTOR Power factor compares apparently power and actual power, and is a measure of how effectively a load uses available power. This measurement requires voltage and current measurements. Current measurement can be done with either internal or external current shunt mode. Power Factor is a “unitless” measure, so the gain accuracy of the measurements does not affect the measurement accuracy.
Page 13 MAINTANENCE OPENING THE MOOSHIMETER WARNING To avoid electric shock, disconnect test leads from the meter before opening the meter. 1. Disconnect all test leads. 2. Unscrew both retaining screws from the bottom of the case with a Phillips head screwdriver. 3.
Page 14 5. Your Mooshimeter is now fully disassembled. The batteries, fuse and reset button are now accessible.
Page 15 CLOSING THE MOOSHIMETER WARNING Risk of electrical shock. Do not operate the meter while partially disassembled. 1. Place the PCB in the bottom enclosure half. Use the “J” shaped fin for alignment with the corresponding cut-out in the PCB. 2. Close the two halves together. 3.
Page 16: Battery Replacement
BATTERY REPLACEMENT 1. Open the Mooshimeter per directions above. 2. Remove old batteries. 3. Observe the battery polarity indication on the circuit board. Insert 2 new AA 1.5V batteries as shown on the circuit board. 4. If you have inserted the batteries with the correct polarity, the Mooshimeter's LED will blink slowly several times before turning off.
Page 17 4. Recommended model: 2. If the resistance measured is greater than 0.5Ω, replace the fuse* Reomax 632.300.12, available from Mooshim Engineering * The resistance mode on the Mooshimeter is not accurate below Size 3AG 12A hold 600V 10kA minimum interrupt 1Ω.

GENERAL SPECIFICATIONS Accuracy is specified for 1 year after calibration within 18 to 28C. Accuracies listed are for single-channel measurements only. Multi- channel measurements may degrade accuracy. For extended specifications visit moosh.im/eter/specs All AC ranges are RMS assuming a pure sinusoid (crest factor √ ). Derate ranges linearly with increasing crest factor. Maximum Voltage between any 600V terminal and earth ground...
