Notes:
[1] Models listed in this column also refer to the “C” version of the model. For example, those rows containing model 115 are applicable to the 115C
as well.
[2] All ac ranges except Auto-V LoZ are specified from 1 % to 100% of range. Auto-V LoZ is specified from 0.0 V. Because inputs below 1 % of range
are not specified, it is normal for this and other true-rms meters to display non-zero readings when the test leads are disconnected from a circuit
or are shorted together. For volts, crest factor of ≤3 at 4000 counts, decreasing linearly to 1.5 at full scale. For amps, crest factor of ≤3. AC volts is
ac-coupled. Auto-V LoZ, AC mV, AC μamps, and AC amps are dc-coupled.
[3] AC Volts Hz is ac-coupled and specified from 5 Hz to 50 kHz. AC Amps Hz is dc-coupled and specified from 45 Hz to 5 kHz.
[4] >10 A unspecified.
[5] Temperature uncertainty (accuracy) does not include the error of the thermocouple probe.

Basic Maintenance
Testing the Fuse (115 & 117 only)
To test the fuse:
1. Set the rotary switch to Ω.
2. Plug a test lead into the v jack and touch the probe to the 10A jack, as shown in Figure 1.
If the display shows a resistance value in the range of that shown in Figure 1, the fuse is good.
If the display reads 0L, replace the fuse and test again.
If the display shows any other value, have the Meter serviced. See “Service Information” earlier in this document.

18 ℃ – 28 ℃.

[3] Specifications are for 4–wire resistance function, or 2–wire resistance using Math Null. Without Math Null,
add 0.2 Ω additional errors in 2–wire resistance function.
[4] For each additional volt over ± 500 VDC add 0.02 mV of error.
[5] For current terminal, > 7A DC or ACRMS for 30 seconds ON and 30 seconds OFF.
[6] Accuracy specifications are for the voltage measured at the input terminals only. 1 mA test current is
typical.
Variation in the current source will create some variation in the voltage drop across a diode junction.

Settling Considerations
Reading settling times are affected by source impedance, cable dielectric characteristics, and input signal
changes. Typically, settling time <1.5s when source impedance less than 1kΩ.

[1] Specifications are for 60 minute warm–up and select 5 3/4 reading resolution.
[2] 20% over range on all ranges, except DCV 1000V, ACV 750V, DCI and ACI 10A range.
[3] Specifications are for sine wave input >5% of range. For inputs from 1% to 5% of range and <50 kHz,
add 0.1% of range additional error. For 50 kHz to 100 kHz, add 0.13% of range.
750 Vac range limited to 100 kHz or 8x107 Volt-Hz.
[4] Specifications are for sine wave input >5% of range. Add 0.1% of the range for the sine wave input is
1%~5% of the range.
[5] For current terminal, > 7A DC or ACRMS for 30 seconds ON and 30 seconds OFF.
[6] Typically 30% of reading error at 100kHz.

Low Frequency Performance

Three filter settings are available:

Slow: 3Hz~100kHz
Mid: 20Hz~100kHz
Fast: 200Hz~100kHz

Frequencies greater than these filter settings are specified with no additional errors.

Settling Considerations
Applying >300VRMS (or >1ARMS) will cause self-heating in signal-conditioning components. These errors are
included in the instrument specifications. Internal temperature changes due to self-heating may cause additional
error on lower ac voltage ranges. The additional error will be less than 0.02% of reading and will generally
dissipate within a few minutes.

Measurement Considerations
All frequency counters are susceptible to error when measuring low–voltage, low–frequency signals. Shielding
inputs from external noise pickup is critical for minimizing measurement errors.

Settling Considerations
Errors will occur when attempting to measure the frequency or period of an input following a DC offset voltage
change. The input blocking RC time constant must be allowed to fully settle (up to 1 sec) before the most
accurate measurements are possible.
