Refer to Resistance Measurement Mode for details. Note: The instrument automatically enters the resistance measurement mode at start up regardless of the last saved setting. If the instrument does not pass calibration, the LCD display will indicate "ER" as shown below. Note: This error could be caused by the clamp jaw not being properly closed or from any dirt build up on the metal surface of the jaw clamp. continued...

Pull the trigger to open the clamp and clamp onto the calibration loop being measured. The LCD will display the resistance value. If the instrument beeps and the LCD display flashes, the resistance measurement is exceeding the critical set alarm. Refer to Setting the Critical Alarms for details. Current Measurement Mode After the instrument has powered up and passed calibration, press the A button to enter the current measurement mode. The LCD display will now indicate AC 0.00mA as shown below. continued... REED Instruments 1-877-849-2127 | info@reedinstruments.com | www.reedinstruments.com...
While taking a measurement, press the HOLD button to save the current reading. While in this mode "HOLD" will appear along with the current stored value and sequence number. Press the button again to resume normal operation. Note: When the Data Hold feature is active the instrument will not turn OFF. continued...
