How to use the OTC700 series digital multimeter to test the frequency and temperature?

When using Hertz and temperature test modes, properly select the method of blocking and connecting the test line.

When using the OTC700 series digital multimeter to test the frequency and temperature, select the specific operation methods for blocking and connecting detection lines as follows.

1.Methods of frequency measurement.

When using the OTC700 series automobile digital multimeter to test the frequency, the method of selecting the stop and connecting the detection line is basically the same as the operation method when measuring the voltage, not much.

2.Method of measuring temperature.

When using the OTC700 series automobile digital multimeter to test the temperature, the temperature adapter module should be used to cooperate with the multimeter instead of directly using the test connector, as follows.

(1)  When the multimeter has selected the temperature mode measurement mode, the temperature adapter module two output pins should be inserted into the "COM" and "V" ports of the OTC700 series digital multimeter.

(2)  Select the C (C) or F (F) reading mode on the temperature adapter module. Then the thermometer is plugged into the temperature adapter module, and then the temperature sensor probe is placed in the position where the temperature needs to be measured, and the temperature can be detected.

Several modes that can be measured using the ohmic (Ω) block and problems to be noted.

When the OTC700 series digital multimeter rotary switch is placed in the ohmic (Ω) gear for measurement, the working power supply of the detection circuit.
