Do not use the meter if it operates abnormally. Protection may be impaired. When in doubt, have the meter serviced. Do not operate the meter around explosive gas, vapor, or dust. Do not apply more than the rated voltage, as marked on the meter between terminals or between any terminal and earth ground.

OPERATING INSTRUCTIONS WARNING To avoid electrical shock hazard and/or damage of the Instrument, do not measure voltages that might exceed 600V above earth ground. Before the use of instrument, inspect test leads, connectors and probes for cracks, breaks, cracks in the insulation.
DC CURRENT MEASUREMENT 1. Red lead lo "VΩmA". Black lead to "COM”(for measurements between 200mA and 10A connect red lead to "10A” jack with fully depressed.) 2. RANGE switch to desired DCA position. 3. Open the circuit to be measured and connected test leads INSERIES with the load in with current is to measure.
4. The forward voltage drop in mV will be displayed. If the diode is reversed, figure "1" will be shown. TEMPERATURE MEASUREMENT (MT-1233C only) 1. Connect the K type thermoelectric couple to "VΩmA" and "COM" jacks. 2. RANGE switch to TEMP position.
MAINTENANCE Beyond replacing batteries and fuses, do not attempt to repair or service your Meter unless you are qualified to do so and have the relevant calibration, performance test and service instruments. The recommended calibration cycle is 12 months. To clean the terminals a) Push the Meter OFF and remove test leads.
5) Replace the case bottom and reinstall the three screws, never operate the meter unless the case bottom is fully dosed. ACCESSORIES User’s manual Set of test leads(CAT I 600V work) K type thermoelectric couple (MT-1233C only)
SERVICE AND PARTS If the Meter fails, check the batteries and fuses first, and then review this manual to make sure that you are operating the Meter correctly...
