The amprobe 15xp b, which the manufacturer writes as 15XP-B, is a compact digital multimeter with autoranging, a non-contact voltage indicator and a tilt stand. It measures AC and DC voltage and current, resistance, continuity and diodes, and it has a TTL logic test. This guide explains what the 15XP-B is listed to measure, and it sets out the places where the manufacturer page and a retailer listing give different figures.

Quick answer

  • The 15XP-B measures AC and DC voltage, AC and DC current, resistance, continuity, diodes and TTL logic, and it has a non-contact voltage indicator for 70 V to 600 V AC.
  • The two sources disagree on the top DC voltage range, the AC voltage range and the safety rating, so the figures below are not merged into one.
  • The manufacturer page does not give a formal safety category, while the retailer lists CAT II 1000 V and CAT III 600 V. Check the label on your unit.

How we chose

The keyword names one model, so we opened the manufacturer’s product page and a test-equipment retailer’s listing. We did not use search snippets, prices or ratings. The manufacturer page is the more authoritative source for the product, but it is short on figures. The retailer listing has the numbers, but it is a reseller’s summary. Where they disagree, we say so below.

Measurement functions

The manufacturer page describes a compact meter with autoranging, VolTect non-contact voltage detection, and an integrated tilt stand. It is powered by a single 9 V battery. The functions it lists are DC and AC voltage, AC and DC current, resistance, a continuity beeper, a diode test, a TTL logic test for digital circuits at 20 MHz, and data hold. The page says it does not measure capacitance, frequency, temperature or battery condition.

The retailer listing gives the same functions and adds a continuity beeper threshold of below 25 Ω and an overload protection feature. Both sources include the diode test and the TTL logic test, so those two functions are consistent across them.

Ranges: where the sources differ

The two sources give different ranges, and the differences matter if you plan to measure high voltage. The manufacturer page lists DC and AC voltage ranges of 200 mV, 2 V, 20 V, 200 V and 600 V. The retailer listing lists DC voltage up to 1000 V, and AC voltage up to 750 V, with the same lower ranges. We have not chosen between them.

The current ranges also differ in one place. The manufacturer page gives 200 µA, 2 mA, 20 mA, 200 mA and 2 A. The retailer listing gives 200 µA, 2000 µA, 20 mA, 200 mA and 2 A. The two lists agree on the top current range and differ on the second step.

For resistance, both sources list 200 Ω, 2 kΩ, 20 kΩ, 200 kΩ and 2 MΩ, and both list a top range of 2000 MΩ. The manufacturer page also lists a 20 MΩ range, which the retailer listing does not.

Safety ratings: the conflict

The manufacturer page does not give a formal safety category. It describes the 600 V AC and DC voltage rating as the highest in this size of meter, and it tells the reader to check the product manual for the official rating. The retailer listing gives CAT II 1000 V and CAT III 600 V, along with CE marking and a listing number.

This is a significant difference. A 600 V CAT III rating and a 1000 V CAT II rating describe different installation points, and you should not pick the more favourable of the two. Read the label on the meter and the manual before you use it on a panel or a supply circuit.

Non-contact voltage and display

The non-contact indicator works on AC voltage from 70 V to 600 V at 50 to 60 Hz, according to the manufacturer page. A non-contact indicator is a first check. It can respond to nearby voltage or fail to respond in some cables, so confirm any live reading with the leads.

The display is a 3½-digit LCD with a maximum reading of 1999, and the meter switches off automatically after about 10 minutes. The sources describe the meter as suited to electronics engineers and field service technicians, and the manufacturer page highlights its TTL and diode tests for component-level troubleshooting.

Step-by-step: a basic voltage check

  1. Check that the 9 V battery is installed and that the leads and probe tips are in good condition.
  2. Insert the black lead in COM and the red lead in the voltage jack.
  3. Select the voltage function. The meter is autoranging, so let it select the range.
  4. Touch the probes to the points you are checking and read the display.
  5. Use data hold to freeze the reading when you cannot see the display at the probe point.

The sources do not give a wiring diagram or a full menu description, so check the jack labels and the function order on the unit in hand.

Where the two listings agree

Several items appear in both the manufacturer page and the retailer listing, which makes them the most reliable parts of this description. Both list autoranging, a diode test, a TTL logic test, a continuity beeper, data hold, and a non-contact voltage indicator for AC voltage from 70 V to 600 V. Both give a 3½-digit LCD. Both describe the meter as having the highest voltage rating in its class, although they give different numbers for that rating. Items that appear in only one source, such as the 9 V battery and tilt stand on the manufacturer page, or the CE marking on the retailer page, should be checked on the unit itself.

What we could not verify

  • The top DC voltage is 600 V on the manufacturer page and 1000 V on the retailer listing. We could not confirm which figure applies to the unit you buy.
  • The AC voltage top range is 600 V on one source and 750 V on the other.
  • The safety category is not stated on the manufacturer page, and the retailer lists CAT II 1000 V and CAT III 600 V. We do not claim either rating.
  • The second current range differs between the two sources.
  • We did not read the Amprobe manual, so the battery replacement and the fuse rating are not covered here.

FAQ

Does the 15XP-B measure capacitance or frequency?

The manufacturer page says it does not measure capacitance, frequency, temperature or battery condition. The retailer listing does not name those functions either.

What is the highest DC voltage it measures?

The sources disagree. The manufacturer page gives 600 V, and the retailer listing gives 1000 V. Check the manual and the label.

Can it find a live wire?

It has a non-contact voltage indicator for 70 V to 600 V AC. Confirm the reading with the leads before you work on the conductor.

What battery does it use?

The manufacturer page says one 9 V battery.

Bottom line

The Amprobe 15XP-B is a compact multimeter with a useful set of diode and logic tests and a non-contact indicator. Because the two sources disagree on voltage ranges and safety category, confirm the rating on the label and in the manual before you use it on any circuit where the rating matters.
