It is recommended for use with local level power distribution, appliances, portable equipment, etc, where only smaller transient overvoltages may occur, and not for primary supply lines, overhead lines and cable systems.

CAT II: Is for measurements performed on circuits directly connected to the low-voltage installation.

CAT III: Is for measurements performed in the building installation.

• Do not exceed the maximum overload limits per function (see specifications) nor the limits marked on the instrument itself. Never apply more than 1000V dc/750 V ac rms between the test lead and earth ground.
• Inspect the DMM, test leads and accessories before every use. Do not use any damaged part.
• Never ground yourself when taking measurements. Do not touch exposed circuit elements or test probe tips.
• Do not operate the instrument in an explosive atmosphere.
• Exercise extreme caution when: measuring voltage >20V // current >10mA // AC power line with inductive loads // AC power line during electrical storms // current, when the fuse blows in a circuit with open circuit voltage >1000V // servicing CRT equipment.
• Always measure current in series with the load - NEVER ACROSS a voltage source. Check fuse first. Never replace a fuse with one of a different rating.
• Do not change the position of the Function/Range Switch while the MIN MAX, feature is enabled. Erroneous readings will result.
• Remove test leads before opening the Battery Cover or case.

Making Measurements

Verify Instrument Operation

Before attempting to make a measurement, verify that the instrument is operational and the battery is good. If the instrument is not operational, have it repaired before attempting to make a measurement.

Range Selection

In addition to autoranging the 37XR-A allows you to manually select and lock a range by pressing the RANGE button. RANGE appears on the display to indicate that manual ranging is active. Each subsequent press of the range button steps the meter to the next higher range. When the highest range is reached the next press returns the meter to the lowest range. To return to autoranging press and hold the RANGE button for 2 seconds. RANGE no longer shows on the display.

Use autorange for all initial measurements. Then, when appropriate, use the RANGE button to select and lock a range.

Warning To avoid electrical shock while manual ranging use the display annunciators to identify the actual range selected.

Correcting an Overload (Oor) - medication

An indication may appear on the display to indicate that an overload condition exists. For voltage and current measurements, an overload should be immediately corrected by selecting a higher range. If the highest range setting does not eliminate the overload, interrupt the measurement until the problem is identified and eliminated. The indication is normal for some functions; for example, resistance, continuity, and diode test.

Additional Features

Input Test Lead Warning

The meter emits a continuous tone when a test lead is placed in the mA or 10A input jack and the Function/Range Switch is not set to a correct current position. (If the meter is connected to a voltage source with leads connected for current, very high current could result). All current ranges are protected by fast acting fuses.

True-rms Measurements

For ac measurements most DMMs average the ac input signal and display the result as an estimated rms value. This average-responding method is accurate for sinusoidal waveforms, but can be very inaccurate for distorted waveforms. To ensure the most accurate measurements, always use a true-rms DMM when measuring ac voltage or ac current on circuits for the following kinds of applications:

• Power Supplies - diodes
• Controllers
  Power Limiting - SCR or Triac
  Starting - motors
• Florescent Lighting - ballasts
• Speed Control - motors
  Pulsed Signals
• Any non-sinusoidal ac waveform

MIN MAX AVG Measurements

The MIN MAX AVG function reads and updates the display to show the maximum or minimum value measured after you press the MIN MAX AVG button. Pressing the MIN MAX AVG button for less than 1 second will put the meter into a mode of displaying the maximum, minimum, average, or actual readings. Each time the button is pressed, the meter will cycle to the next display mode as shown in the table below. Press the MIN MAX AVG button for more than 2 seconds to disable this feature.

Button Display Value Displayed
< 1 second	REC MAX	Maximum value after feature activated
	REC MIN	Minimum value after feature activated
< 1 second	REC AVG	Average value after feature is activated
< 1 second	REC	Actual reading, min max being recorded.
>2 seconds Exit MIN MAX AVG		Normal measurement, actual reading

Peak Hold Measurements

Note: The PEAK function calibrates itself to meet the specifications.

Peak Hold records and stores the positive and negative peak values that occur while measuring ac current or ac voltage. To enable the Peak Hold feature press the PEAK button for more than 2 seconds. The display will show CAL to indicate the calibration cycle is in process. After the CAL indication clears, press the PEAK button again to display the maximum (P+) value for the ac voltage or ac current being measured. The display will toggle between the P+ and P- readings each time the PEAK button is pressed. Press the PEAK button for more than 1 second to exit the PEAK function.

Beeper Off

The beeper is an aural indicator to identify when the DMM is performing a function, making a range change, detecting a limit, and so on. To disable the beeper use the following procedure:

1. Set the Function Switch to OFF.
2. Press and hold the HOLD button while turning the Function Switch to the desired function. The no-beep symbol shows on the display.
3. Release the HOLD button. The Auto Power Off feature will remain disabled until the meter is turned off and then on.

Note: To disable both the beeper and Auto Power Off press and hold the REL button while turning on the DMM.

Auto Power Off

Auto Power Off is a battery saving feature that puts the meter into a sleep mode if the Function/Range Switch has not changed position in the last 30 minutes. To wake the meter turn it off and then on.

The Auto Power Off feature can be disabled to keep the meter from going to sleep. This feature is useful when using the MIN MAX mode for extended periods. To disable the Auto Power Off feature use the following procedure:

1. Set the Function Switch to OFF.
2. Press and hold the MIN MAX AVG button while turning the Function Switch from OFF to the desired function. The SLEEP OFF message shows on the display.
3. Release the MIN MAX AVG button. The Auto Power Off feature will remain disabled until the meter is turned off and then on.

Note: To disable both Auto Power Off and the beeper press and hold the REL button while turning on the DMM.

REL (Relative) Measurements

The Relative mode displays the difference between the actual reading and a reference value. It may be used with any function or range. To make a relative measurement first establish a reference value by measuring a value and then pressing the REL button after the reading has stabilized. This stores the measured value as the reference and sets the display to zero. The meter subtracts the reference value from subsequent measurements and displays this difference as the relative value. Measurement values greater than the reference value will be positive and values less than the reference value will be negative.

To exit the Relative Mode, Press and hold the REL button for 2 seconds.

HOLD Measurements

The HOLD button causes the meter to capture and continuously display a measurement reading. To use the HOLD feature make a measurement, and then, after the reading has stabilized, momentarily press the HOLD button. You can remove the test leads and the reading will remain on the display. Pressing the HOLD button again releases the display.

Backlight

Pressing the button illuminates the display with a blue backlight. The backlight will automatically turn off in about 60 seconds. Frequent use of the backlight will decrease battery life.

Product Maintenance

Cleaning

To clean the meter, use a soft cloth moistened with water. To avoid damage to the plastic components do not use benzene, alcohol, acetone, ether, paint thinner, lacquer thinner, ketone or other solvents to clean the meter.

Troubleshooting

If the meter appears to operate improperly, check the following items first.

1. Review the operating instructions to ensure the meter is being used properly.
2. Inspect and test the continuity of the test leads.
